- Moby 50cc air cooled:
I sold my bidalot engine and rebuilt quickly a 50cc doppler engine for the Arpil race. I’m using a cheap Teknix crank $75 to put it to the test and a stock cdi “Le partie” $75 from Treatland.tv with a new high quality coil.

- Peugeot RCX 50cc h2o Bidalot:
Since the last race fall 2012, I stiffened the EBR fork, cut off some of the clutch pulley shoes for better take offs and accelerations, also went up 2 teeth from 72 to 74 rear sprocket to be quicker off the turn since the bike couldn’t hit top speed on the short straight away.
Depuis la derniere course automne 2012, j’ai durci la fourche EBR, couper la gomme des machoires de poulie pour des meilleurs departs et accelerations, aussi monte’ de 2 dents de 72 a 74 sur la couronne pour des sortie de virage plus rapide vu que la machine n’atteignait pas sa vitesse de pointe dans la ligne droite assez courte.

I haven’t been posting articles as frequently as in the past for few reasons.
I’ve been very busy… writing and keeping up a blog takes a lot of time. I didn’t want to saturate the blog with too many articles making it difficult for the new blog readers to catch up having to go back through so many previous posts. I started to post more about the Tomahawk activities on the right side of the main page but realized that a lot of people only surf the web with their iPhone and completely miss all the frequent updates because the right side is not displayed on their small phone screen.
Some people have asked me to start posting more, so here’s what’s going on a the Tomashop…
- DUAL 103 SOLD:
I just finished the Dual Variated Peugeot 103 and sold it to a friend for $2,300 a steal considering the rareness of that set up, some of the vintage Polini and Giraudo parts, the amount of work, powder coating, disc brake, etc… My consolation is that it stays within the family and will be taken care of. It’s a unique piece of art that we won’t find in the streets anytime soon.
I’m hoping to do a good photo shoot sometime in the beginning of April and maybe bring a video.
This is not a top speed bike more like a cruiser with 50 mph top speed. By design a dual variated transmission absorbs a lot of the engine’s true power and needs to constantly rev high. It makes it harder to tune the transmission for perfect overall power.
Polini air cooled 50cc W kit ported – Vintage Polini 50cc h2o head – Polini cases small reeds – Doppler crankshaft small taper – MVT internal cdi variable advance – Dell orto 19mm carb – Simonini circuit pipe (just for the photo) but changed to Giannelli Black Gun better high rpm pipe – stock clutch – Vintage Giraudo variator – Vintage dual variated swing arm – Yamaha Zuma scooter radiator – Polini water pump modified with timing belt pulleys.
1989 Peugeot 103 frame flat tank sides, imported from France – Honda CT70 rear gas shocks 330mm – Peugeot seat with custom upholstery – EBR hydraulic fork – custom disc brake adapted to stock 1978 spoke wheel – Tomahawk fork brace – Red candy apple and Flat black powder coating.
- MOTOBECANE AV10 – 90′s MBK Magnum Racing XR F1 Assistance:
This is a restoration project for a customer.
A super rare moped that we won’t see anytime soon in the US, on a blog or even less running on the streets. It took the owner at least a year to hunt and import all the parts from France. We’re going to try to restore the bike close to the 90′s stock looking version with that original hot pink paint by importing an MBK scooter model small fairing with the exact same paint match, the vintage moped pink fairing is too rare and too expensive. But the motor won’t be 50cc h20, it will be a Parmakit 70cc air cooled for now.
The original 90′s F1 Assistance (stock 50cc h20, kick start, disc brake, etc… $1,600 back then) and the Tomahawk project:
1996 Scooter MBK Rocket F1 assistance series fairings that we need for a color match:
I just got the stock hydraulic 30mm Paioli fork back from polishing satin finish and already rebuilt it with new oil and dust seals imported from France by Yamaha Genuine parts.
- TOMAHAWK Moby av10 race bike 2013:
I built a new Polini 50cc h2o stock cases 21mm carb for my motobecane race moped but the chassis upgrades are far from being done, radiator, electric water pump, battery, temperature gauge, square swing arm, aluminum launch lever, 3 star mag wheels, custom bracket for rear aluminum sprockets, 250mm scooter disc brake, grimeca caliper, custom bracket, Paioli 30mm adjustable hydraulic fork missing 2 special aluminum washers to be machined.
Mbk Booster front 250mm disc by Doppler, perfect bolt pattern match for the Mbk 51 magnum 3 star front wheel.
There’s a motorized bicycle race event in Southern California coming soon Saturday April 13 at Grange’ race track in Victorville. Few mopeds are invited and I want to bring that bike to the track as well as my Peugeot RCX 50cc h20. So I need a temporary engine.
I’ve just rebuilt a ported air cooled 50cc Doppler kit, stock cases, 19 carb and will also use that oportunity to test the cheap Teknix crank $75 and a new high quality internal ignition coil replacement for the stock cdi $75 “Le partie” sent by https://www.treatland.tv/motobecane-CDI-p/motobecane-cdi-ignition.htm
I’ll bring some reviews on the Teknix crank and cdi internal coil after the race in April.
I’ve already made the Part 1 videos. Check out those links:

Good time last Friday Feb 1st, 2013 at the Grange’ race track in Apple Valley (1h30 from Los Angeles), watching a private moped race event organized by Fink’s moped store in San Diego.
I met a very good group of people that might come back to Grange’ in April to participate in the Southern California motorized bicycle/moped event, first official race of the season 2013.
Here are few pics and a video of my trip to the track…

I fired up the Motobecane 40T 50cc malossi liquid cooled after one week of work.
This is a commissioned bike but I didn’t build the engine. I just hooked it up, installed and timed the cdi + new rubber mount dell’orto 19mm carb with the right settings. Also serviced the variator. Lots of work and small custom parts to make everything fit on that bike.
I replaced the unnecessary polini 4 petal reed block with the stock 2 petal athena reed block for better 50cc performance with the stock cases, the carb even clears the frame much better now. I installed a launch lever + tomahawk Xtreme clutch pulley kit.
I also converted the front wheel loose bearings to sealed bearings, installed a disc brake with custom caliper bracket.
I installed the lights, brake light, horn, kill switch, water temperature gauge.
Video 1sr start:
Some serious h20 50cc power with stock cases + 19mm carb + stock cdi. I still need to adjust the water pump belt, install the variator belt and drive chain.
After testing a different type of a needle close to the one I normally use, the bike felt rich during the first test run. I went back to old needle set-up, down jetted the carb, tuned the variator but toned it down for daily street use. The bike runs good but I’m waiting for a water temperature gauge to get a reading at top speed and make sure the too small polini radiator is able to cool down the engine. Normally when ported that malossi 50cc kit gets more hp but looking at the exhaust it didn’t seem like the cylinder was ported but just mounted stock. Still plenty fast for a 50cc daily rider.
I’m rebuilding a peugeot 103 engine with 50cc malossi kit + stock cases.
Here’s what happens when you use the high compression malossi head for 50cc or 70cc with decompressor option. They made a tiny hole in the combustion chamber to give you the option to either use a decompressor or a plug it from outside. The problem with that bad design is that hole creates a heat bubble at top speed and will blow up a hole in your piston or combustion chamber. It’s better to use the malossi head no decomp version. Or if you want to use a high performance head with decomp for 50cc or 70ccc the best is probably the polini one, you can always plug it as well. (not as good performance as malossi or doppler but much better than stock head)
Malossi high comp head decomp vs no decomp version
Polini and Doppler high comp heads
Be careful when port matching the peugeot stock cases. There’s not much aluminum for the secondary rear transfer port, it’ very easy to drill a hole. It’s better to find somebody who can weld your cases with aluminum or be conservative with the porting. I don’t recommend to use JB weld to fill up a hole in the cases, it might crack at high temperature.
Also, on the variator clutch side, make sure to use the right metric screws for crank seal cover plate. It can easily come off and rub against the clutch bell. When buying an after market peugeot variator, you should disassemble it and check every parts. Most of the time you have to grind the balls plate, thrust plate spring, and nylon washers before installing it. Test each single part on the crankshaft first to make sure the slide perfectly but don’t over grind them.

PEUGEOT h20 SUMMER COCKTAIL:
Almost done with Melvin’s Peugeot 103 RCX Doppler engine.
Start by machining the cylinder top deck and head to modify the port duration and compression ratio, mix some peugeot polini cases small reeds with a motobecane polini intake manifold, cut and adapt some malossi vl7 4 petal reeds to replace the polini 2 petal reeds, add a small drop of locticte, hand cut few paper gaskets, port the exhaust as a nice finishing touch and serve with a fresh dell’orto 21mm carb for a powerful 15hp liquid cooled 49cc cocktail.
Melvin might decide to use the peugeot engine on a lighter motobecane frame.

The Tomahawk shop in Filipino town is done.
My back is sore but it was worth it. It’s a nice little nest to build custom bikes, repair and restore mopeds. We’ve got the tools, the bikes, now we just need to hang a photo of a moped babe to make it a ligit shop.
It’s party time tonight Friday night at 7:30pm. Come and hang out with us. Honest Mike from Scoot TV will be there to cover the event. I saved plenty of room on the red doors for his stickers, yeah!
Next Monday I’m finally back to fixing mopeds, I can’t wait. We’re gonna build some amazing bikes there and we’ll happily serve the LA moped community.
Thanks everybody for coming, it was really fun. We’ll try to throw more moped parties in the future.

Tomos ST 50cc 2-speed automatic, auto mix oil injection.
This bike was supposed to be a commissioned top tank project but it didn’t happen. So I decided to keep it as my new daily ride. I’ll eventually convert it to a top tank later.
I’m having so much fun and will keep it stock during the break in period. But I’m sure it’s just a matter of time before I open up the engine to modify the clutch, secondary transmission, port the stock cylinder, modify the stock pipe, and upjet the carb for better top speed at barely no cost.
Compared to my custom motobecane or peugeot mopeds I noticed right away that Tomos stock mopeds don’t feel very stable. But I guess I’ll get used to it and adapt my riding style. I kinda want to race it against other stock Tomos mopeds Sat June 2nd at Grange’ race track.
First day out and I already got some compliments at the corner market. A 2012 Tomos moped doesn’t look as cool as a custom vintage moped but still gets noticed for only $1300 ST version and $1100 Sprint premix fuel/oil version (no turn signals, small headlight fairing).
Smooth ride from Tomashop Filipino Town to Downtown LA – Disney Concert Hall.

The Tomashop is almost done. We’re gonna throw a little BBQ party for the grand opening next Friday 18th starting at 7:30 pm. Very casual, stop by and say hello.
Look what I spotted on the parking lot of Home Depot, a rare Citroen 2cv “two horsepower” (taxable 2hp), rad…
Incroyable, une “deux chevaux” garee sur le parking d’un grand magasin de bricolage pres de chez moi (genre Le Roy Merlin). La 2cv a ete importee aux USA a environ 1000 exemplaires mais n’a pas connu de succes a une epoque la ou tendance etait plutot a la grande voiture avec gros moteur.
2CVAlthough the 2CV was a tremedous sales success in Europe and throughout most of the world, when it was introduced with little fanfare to the American public in the early sixties, it became quickly apparent that the 2CV was an impossible sale to the average American driver. In the sixties the American auto manufacturers were still competing as to who could produce the biggest car with the largest engine and the flashiest fins. The fuel-efficient, underachieving, oddball-looking 2CV was a laughable abnomaly to the American buying public. Little more than a thousand were sold in less than a ten year period and, in 1970, several dozen were destroyed by Citroen when left-over models from the previous model year could no longer meet the increasingly stringent DOT standards. Citroen decided that destroying these unwanted 2CVs was more economical than shipping them back to France.
Much of the USA’s current 2CV population was imported in later years by enthusiasts (some with incorrect registrations and ID plates). The 425cc models are the most readily available but not really practical for anything other than around-town driving (as are the earlier 375cc models). The 602cc-engined Deuches can keep up with most of America’s traffic flow and parts, for the 1970 and on models, are also more readily available. Be wary of buying Eastern and Northern cars as the scantily-clad 2CV’s sheet metal is a magnet for rust (especially in the floor boards and wheel arches). Fortunately, with the aid of a repair manual, the car is easy to repair and home restorations, although just as time consuming as any other car, are certainly possible.
Manufactured from 1949 to 1990
Probably between 800 to 1,000 in North America
How the latest 2cv models were fabricated in the 1990 in Portugal to please the passionate customers after the production which started in France in 1948 stopped in 1988.
James Bond escaping with a Citroen 2cv:
Melvin the moped ninja is working on James stretched Honda Hobbit:
I measured the Hobbit original length from axle to axle approximately 43 1/4 inches. After stretching the frame the length was 45 inches just like the green Puch free spirit top tank . So the modified Hobbit frame is not too long but will actually handle better than stock. Fast hobbits tend to wheelie too easily and the light front end feels too dangerous at top speed. We also modified the swing arm to clear the air filter and make it easier to service the carburetor without having to take the engine down every time.

Finally a place to put all my stickers. I knew there was reason I kept them for 3 years.
I just found some cool photos of two moped builders latest projects in France.

- Cafe’ Peugeot 103 dual variated project by Tomahawk:
I got inspired tonight and started working on a side project. I haven’t built a Peugeot 103 for a while and missed it, that bike got me excited again. Even though it’s going to be hard to let go that rare dual variated swing arm, I’m thinking about selling the bike for a reasonable price. So if anybody is interested in commissioning the project, email me before I finish it. I’ll try to keep the cost down using used spoked wheels, used ebr puch magnum fork and adapt an affordable front disc brake (safer) or used stock peugeot fork with drum brake, stock shocks or affordable upgraded ones, decent tires, used Tomahawk clipons, work on the seat, etc… I haven’t decided about the paint yet, I might keep it as is for now.
The best set-up with that dual variated swing arm is a high rpm 50cc kit. I might also include that rare vintage race track Bidalot 50cc kit (ported) with special cooling fins. I raced that engine at the 2010 polini cup and once tuned perfectly it’s very powerful, faster than most 70cc. I’ll replace the the thick 103 spx Giraudo racing crank with a standard 103 racing crank to adapt any standard small taper variators on the market. My second option is the small polini or 1977 cases with a polini or doppler 50cc kit from Treats. The bike should have fast take offs with decent top speed and fun to ride on the weekends, intriguing friends and neighbors.
Peugeot vintage race track Bidalot Radial 50cc kit:
Disassembly of my first generation Bidalot race engine, old school, imported from France in 2009. Bidalot 50cc kit air cooled, Giraudo 103 spx crank, high rpm FAG celeron riveted bearings, stock 2 port cases with creation of 3rd port, polini single flat reed, Bidalot intake manifold, 19mm carb. The port matching was done poorly and the cases wrongly assembled with gasket + silicone but the kit still blasted. Before heating the cases, I noticed a thin crack in the left half case, it might have affected the engine’s power causing air leaks during my last few races. I’m not sure what happened, it could have been caused by the front wheel hitting the engine and knocking the cylinder head off center, during my first crash when I bent the front fork doing a full spin with my bike. Or the thin ported cases may just have had a weak spot. Now I definitely need new engine cases
Head gasket after my crash. Bidalot racing gaskets have multiple aluminum layers to modify your squish.
Since everything is bigger in America, I could also use one of my 70cc kits in stock (malossi and polini W port) with air cooled or h20 head. It wouldn’t be as fast as with the 50cc kit but more like a low rpm torquy cruiser bike, still with fast take offs.
I’ve got most of the parts in stock, pedals, controls and cables, mvt cdi, bearings and seals, 19mm carb, stock clutch + rad vintage GIRAUDO racing variator. All I need to complete the bike is new shocks, maybe a disc brake assembly, headlight, tubes, engine cases + crank.

So this is it. I’ve made the decision to use a motobecane Av10 moped frame instead of my Hodaka motorcycle top tank frame. It will be lighter and faster.
I’ve got 2 months to cut, grind, weld, order all the missing parts to finish the project and register the bike as a moped by the end of March for the “Super Sunday” big Ruckus ride in Los Angeles.
I’m super excited about that project but no more talk, it’s time to build.

This is a Peugeot bottom end engine I properly reassembled today and ready to ship back to Canada for a top tank moped project.
I’m specialized in Peugeot and Motobecane variated engines my first choice of mopeds but can also work on Puch and Tomos engines stock or kitted.
Just email us at firstname.lastname@example.org for quotes since every engine project is different and send us your parts or ask us some advice on what parts to buy.
And YES…. we can build your custom moped too!
Keep in mind that a vintage custom moped built from scratch with brand new parts is not cheap and to build it right with quality like all the Tomahawk bikes it takes an average of 50+ hrs of labor, that’s if there’s no special custom frame modifications request.
Just a vintage moped frame can cost up to $200, good mag wheels $200, Ebr fork $200, disc break assembly $200, standard rear shocks $60, handle bars – controls – head light – cables – pedals – chains, seat, etc… another $200.
So a $1000 just for the rolling chassis + paint job.
Plus close to $1000 in parts for a fast brand new race engine built from scratch. A brand new stock engine is a little cheaper but still around $600 in parts.
Here’s my personal experience:
The fun thing about mopeds is that it’s supposed to be cheap and do it yourself. Fast vintage custom mopeds are a whole different world. People buy a cheap vintage moped and try to learn to fix it themselves. It’s fine as long as they keep the engine stock but once they decide the bump the power with performance parts, it’s just the beginning of a long, painful and expensive road.
Over and over I see people wanting to build their own kitted engine to learn and save money. But most of the time they end up spending more in the long run after seizing multiple kits or breaking their engine parts. After few months of frustration, they finally bring the bike to an expert which they should have hired in the first place to really save money. It takes even more labor for a mechanic to repair a damaged engine than building one with new parts.
In conclusion, their is no cheap vintage custom moped and fast. The only cheap moped is a stock vintage one which you got a good deal for and that only needs little maintenance once in a while. Or, a brand new Tomos stock-ish engine reliable with a pipe and up jet for daily commuting at 45 mph max, and maybe little extra money spent on chassis parts to make it look less boring and more custom.
That’s just my opinion but I hope that it helps those who are new to the moped world or want to build a custom bike.
Single variated transmission:
Dual variated transmission:
6 speed transmission:
Among many brands, a Bidalot 50cc and 70cc kits for 6 speed minarelli AM6 engines.
Plus, French-German company Maxiscoot/MXS racing latest prototype with their new 90cc kit (2 years development) available on the market by 2012 for minarelli horizontal scooter engines and 6 speed engines like minarelli AM6, Derbi euro 2 and Derbi euro 3.
Can you imagine that sweet 6 speed 2T euro technology available and easily adaptable for our french variated mopeds? Hmmm… let me see if I can work on that this year.
Look inside Maxiscoot/MXS custom shop, working on their 1st air cooled 70cc kit 18.5 hp one of the most powerful for vertical minarelli Zuma 50cc scooter engine.
This is what I made with a friend and my son of a 2005 Ramzey Comfort (which is a Turkish Peugeot 103 clone with kick start as you might know).
We’ve built the moped for my girlfriends son’s birthday next week. Today was the first time on the streets of Amsterdam and it attracted a lot of attention from passers by.
We bought the original bike for €50 and managed to keep the total cost at about €250, by using a lot of second hand stuff from adds on the internet.
We visited the tomahawk website often after my son discovered it last year when he got an old Peugeot 103 for his eleventh birthday from my father as a learning project.
Through this email I’d like to thank you for the inspiration.
Keep up the good work!
So far so good…
The 1st batch is here! The clip-ons will be FOR SALE very soon here on the Tomahawk blog and at Treats http://www.treatland.tv
Working late nights getting the clip-ons ready, compressed air cleaning, thread and quality control, aluminum 7/8 tube cutting, Allen screw assembly.
Perfect racing position with a fix 8 degrees angle just like on my Peugeot 50cc race moped.
- BONUS PICS:
Sneak peek at the “Transformer moby” project by Overkill (chassis) and Tomahawk (race engine).
Stock av10 cases ported, Doppler kit 50cc air ported, Malossi crank, Doppler stock reeds, Dell’orto 19 carb, Doppler pipe, Mvt cdi, Bidalot Junior variator, Doppler clutch pulley, stock engine spring, launch lever. Probably an h20 50cc set-up in the future.
Check out the size of that fat rear tire (3 inch tubeless) with the wide stock mbk av10 magnum square swing arm! I can’t wait to see the future gas tank side covers with aluminum CNC machined motobecane raised 3D logo.
Engine cases disassembly:
Case matching + billet LED tail lights:
Setting the transfers and exhaust port duration at Gr1 moped racing specs + Bidalot variator.
The engine is built so tight with precision.
All surfaces were carefully checked. The crank perfectly centered. The cases are assembled with special crank seals not available at any moped part store, new grade 8 7mm bolts + stainless steel spacers. The head is mounted with malossi long nuts M7 and stainless steel thick spacers + O ring and professional super resistant sealant. The squish is safely set for 91 octane fuel. Blue Loctice applied where needed.
Next is the ignition with timing set for high rpms + aluminum welding inside the intake manifold to match the stock reed block for a perfect gas flow.
Even though the cylinder is not lubricated yet on that video, the compression is already very strong! Just what we need for crazy 50cc power.
I’m getting ready to build my cafe scoot /drag ped project powered by a minarelli 77cc 23hp dual variated scooter engine. I’m still undecided and looking for advice. Please check out my last post on mopedarmy to help me take a decision, thanks.

So it looks like in January 2012 Tomahawk is finally leaving the underground “James Bond room” for a bigger shop at Overkill high end baja buggy parts in Anaheim, Orange County. Perfect location in an industrial zone to build and test screaming mopeds all day long.
I’ll keep an antenna in Hollywood for small projects and moped repairs but I’ll use the new shop to build all the future custom bikes. With our new fast mopeds we’re gonna show the Ruckus scooter people of OC what’s up. I’m also working on fabricating future Tomahawk moped parts:
Some aluminum clipons with steel chromed tubes for 28mm moped fork like the EBR and maybe later 30mm for Tomos fork, with future options like anodizing, powder coating, tubes stainless steel, titanium, etc… Also an aluminum launch lever with bearing that mount on the pedal shaft for pegs or pedals use + a bracket ready to bolt on motobecane or peugeot engine cases. The launch lever is a must-have part on those variated french bikes to get the most out of your engine by pressing down on it with your foot. It’s like downshifting on your variated transmission, it gives you that extra power that no other moped offers (even with a dual variated transmission), launching the engine into high rpms for quicker accelerations to reach top speed or be the fastest climbing hills.
I’m also going to design and test a new engine spring for peugeot and motobecane since none of the polini or doppler works perfectly. I’m trying to work on a new Tomahawk clutch pulley or a heavy duty kit to upgrade your doppler clutch pulley ER2. And a bunch of other parts needed for french bikes and later think about good parts for Puch and Tomos.
We’ve got a couple of projects lined up, another fast 50cc Doppler motobecane av10 project, the “Motomos” a Tomos A55 with custom extended swing arm top quality welds and streetmate front end disc brake with maybe a motobecane variated engine, my Tomos ST Harley top tank and my Minarelli 77cc h20 drag moped. There’s gonna be some long nights but let’s do this thing!
More frames waiting for a Tomahawk extreme makeover:
Black Peugeot 103 vogue short swing arm 50cc h20/air cooled, Green peugeot 103 RCX short square swing arm 70cc polini h20, White peugeot 103 mvl dual variated swing arm with high rpm vintage Bidalot racing 50cc air cooled and wide 2.5 inch mag wheels with stock threaded holes for disc brake, Yellow old new stock motobecane av10 frame zero miles not even a single drop of gasoline in the tank. How do you like that moby frame drg7? I know know you want it bad.
For a man of means, a future 25hp 86cc h20 monster peugeot or motobecane moped using the CNC machined Mykitech cases from http://www.treatland.tv to adapt all the powerful high tech minarelli scooter parts imported from Europe + the Mykitech clutch pulley.

A little window on the growing Brazilian moped scene.
I’ve been told that Motobecane is the most popular brand and I think the only one that was imported in Brazil, some models were built with tubular frames like the Mobylette XR. Their bikes are super cool and fast reaching 80mph top speed tricking their stock engines or using whatever is available. Performance parts are rare with no moped store and expensive in Brazil with crazy customs taxes when imported.
They’re just starting to get some good stuff from the US like the Doppler ER3 variators thanks to Treats http://www.treatland.tv, and trying to learn more about how to tune their variated AV10 engines french racing style reading the Tomahawk blog. I don’t know if they’ve mastered the launch lever with proper variator tuning yet but they’ve discovered the nitrous boost kit and the Redbull baffle… rad!
Thanks Augusto (blue XR) and Vincius (navy blue av10, orange XR) for providing the pics and links. If I made any mistake let me know. PS: I don’t know if you watch UFC mixed martial arts but I’m a big fan of Anderson Silva Brazilian fighter.
Videos of moped meeting, street and freeway races, plus WMX motorized bicycle AV10 engine with an awesome guitar soundtrack:
For those who are new to the Tomahawk blog and motobecane french variated mopeds. Here are some old classic videos I posted 2 years ago of a friend and master tuner in France (Remi), showing the power of a motobecane av10 50cc h20 Bidalot engine big intake 30mm Keihin carb with a Bidalot clutch pulley. It’s also a good reference for those who build fast 50cc mobys, it gives a good idea of what a powerful and perfectly tuned 50cc engine should sound like. Use it to tune your bike just like you would tune a musical instrument and compare with the sound of your engine’s videos.
In the 2nd video test run, the engine spring and variator weights + launch lever are perfectly tuned causing the belt not at ideal temperature yet to grab a little weird making the powerful engine swing back and forth but it usually stops once the belt gets warm and you can counter that effect by pressing with your foot on the launch lever. Cf 90 doesn’t mean it’s a 90cc it’s the motobecane av10 year model 1990, listening to that crazy engine I’ve had people asking me and getting confused, it’s just a 49.9cc only allowed for moped racing in France anything bigger is by law registered as a motorcycle, pedals or no pedals. I’ve actually test rode that bike during my last visit in France and never felt anything like that on a moped before, it sounded and felt like a powerful 80cc kit.
PLUS, if you don’t mind fairings on mopeds, here are some of the nastiest motobecane av10 h20 and peugeot 103 moped builds in France have seen so far:
Special thoughts for a moped friend Daniel Nguyen from the Woolly Bullies moped gang and his family. Daniel was a super cool guy full of life, he recently tragically died in LA too young at 28 years old. It’s a very sad time for the moped community. It reminded us how precious life, family and close friends are. Keep riding your mopeds and Carpe Diem!
Tribute video by Honest Mike:
Here’s my next project.
Today, after running into one of the top Ruckus builders in LA at a racing hardware store, I decided to start my cafe scooter project and get it ready for the next big Ruckus ride March 2012.
I’ve stored the parts for over a year and it’s time to build the bike. I like anything fast on 2 wheels but I prefer to build small bikes. I won’t consider this bike a moped or a scooter but more like a prototype 2 stroke motorcycle 77cc dual variated. I’m gonna try to mix the look of old cafe racers with modern euro 2 str0ke scooter technology. It should be a fun project. My engine setup is actually outdated now compared to what the drag scooter racers are using in Italy, France, Germany, UK, etc…
I’ve seen pics of old cafe racers with Lambretta engines but this bike should be pretty unique in the States, especially with a fast 2 stroke scooter engine. Everything is 4 stroke now in the scooter and motorcycle world in the US since the big Japanese manufacturers like Honda have started pushing and imposing their 4 stroke engines for financial reasons on the streets and race tracks.
I’m using a 23 hp 2 stroke minarelli horizontal scooter engine imported from France (Mbk nitro/Yamaha Zuma) with malossi 77cc h20 kit, malossi crank 85mm, stage 6 digital cdi, dell’orto 28mm carb flat slide, stage 6 R1400 exhaust, malossi over range transmission kit, stage 6 clutch pulley, stage 6 gears.
I’m using a vintage Honda 2 stroke motorcycle frame. I will probably cut the frame to rethink the lines and weld the scooter engine mounts. I was originally going to use a step-through motobecane av10 frame but I changed my mind and got a top tank frame. I hope it’s not a crime to chop that vintage bike. I’m using a scooter aprilia RS 13″ rear wheel with disc brake and a motobecane moped 17″ front grimeca mag wheel with stage 6 rotor and brembo caliper. I haven’t decided about the fork yet.
I might also change my mind and decide to stick with the original plan using a super light motobecane av10 moped frame to get the most out of the 23 hp engine and be able to ride the bike “legally” as a registered 50cc moped, I just wont be able to carry much fuel. The motorcycle Honda frame has no VIN number and feels super heavy, I might still build that cafe bike but strip down my registered TGB scooter and mount the 4 stroke 150cc GY6 engine to use it as a rad and reliable daily commuter.
Some photos of the parts + the 1st motobecane prototype that inspired me 2 years ago and one of my old sketch exploring different frame + seat options.
Here’s the sound and acceleration of a minarelli engine with the malossi 77cc big bore kit on a 50cc scooter Yamaha Aerox/Mbk Nitro. The 50cc Yamaha Zuma in the US also called Yamaha BWs or Mbk booster in France, uses the same engine type but there are many versions of kits depending on the year model, before 99′, after 99′, after 03′.
Don’t we love the power of 2 stroke engines? It’s only a 95cc. Try to match that with a same size 4 stroke engine.
Here’s a drag scooter with a 2Fast cylinder kit + Nitrous fuel built by http://www.maxiscoot.com a young french company that sells high end performance parts and is actually located outside France since the laws there don’t allow to sell kits above 50cc. They also own MXS custom that builds some of the sickest and fastest scooters and competes all year long.
32 hp at the rear wheel by MXS Custom, 2Fast 86cc kit + Cristofolini 80cc exhaust.
Here’s another drag scooter 2 stroke twin cylinder engine (probably 2x 86cc, one of the latest hot engine setup in Europe right now) by ALP design sponsored by http://www.maxiscoot.com
What’s going on lately with all those peugeot TSM on the streets. I thought they were super rare in the US. That’s the second one coming to the shop for an engine rebuild. I don’t complain though, even if I didn’t grow up with peugeot top tank mopeds, I’m starting to really like them.
Here’s what’s on the menu:
Replace the stock cylinder with a Gilardoni 50cc kit + dell’orto SHA 15 mm carb + polini flat single reed valve + simonini circuit pipe, everything else stays stock. This is my favorite engine set up for a peugeot moped with 45 mph top speed, reliability, fuel efficiency, and easy port matching with the new stock 3 ports cases. That TSM has the 2 ports cases 70′s model so I need to create a 3rd rear port to match the cylinder.
The simonini circuit pipe is a great low and mid range exhaust with a popping sound and also clears the pedals easily but I may have to lose the center stand… not sure, and maybe cut + weld or bend the baffle to fit it in a tight spot between the stand and the pedal (you can also slightly bend or shave the pedal arm). For greater top speed I would recommend a Giannelli exhaust but you definitely have to lose the center stand and slightly bend the pedal or mount the pipe low.
Here are some pics of my very first peugeot 103 project in the US with a used 50cc stock engine 3 ports imported from France + 15 carb SHA + Giannelli pipe dopller baffle. That bike had good gas mileage and 50 mph top speed with stock cylinder exhaust port slightly modified, I miss that kind of engine set up. Then I pimped it with powder coating, chrome plating and a Ponili 70cc kit + malossi cases.
Peugeot TSM engine disassembly and rebuild with Gilardoni 50cc kit, case port match, modified port duration, new crank seals:
Same stock-ish 50cc engine setup available at Treats, http://www.treatland.tv:
Pics of the bike rebuilt with the new engine and video of the 1st start. Notice how the simonini circuit baffle barely clears the swing arm and the pedal even after bending the arm a lot to give it a wider S shape. I can pedal start the bike but once the engine gets in high rpm and swings back it’d probably be safer to ride it with the right foot forward or bend the pedal arm even more but it will get way shorter than the left arm.
Video 1st start, the carb is not tuned yet:
Vintage dual variated swing arm right side transmission for peugeot TSM and 103 fast take offs.
This is the first Tomahawk Tomos project using a brand new 2011 ST model.
The step through tank will be chopped off with a tomahawk and replaced with top and lower tubular cross bars to mount the 2.5 gallon fuel tank. The bike will get a custom paint, a bullet headlight, low rise handlebars and probably a long seat.
No major modification will be done in order to keep the bike reliable and fuel efficient. The stock exhaust might be modified, the carburetor upjetted and the rear sprocket downsized for better top speed.
It should be a fun bike with a retro touch but keeping some of the Tomos ST lines, and should also offer convenient daily commuting with the auto mix oil injection and the large capacity fuel tank reducing stops at the gas station.
Parts from http://www.treatland.tv are already on the way.
Edison’s custom Puch Free Spirit top tank built by Melvin in Filipinotown, Los Angeles. The stock engine runs like a clock. Cool bike, well done guys!
Plus, my dad’s oil painting for my birthday ready to be shipped next week from France. Can’t wait…
Check out that cute blog “Les Mobyletteux” (the mopeders) that talks about two french students who have just discovered a new passion for mopeds. They plan road trips with their motobecane av88 and try to learn the basic mechanic skills.
After delivering the TSM last Tuesday the bike seized, apparently at fast top speed going up hill and returned to the shop that same night for a check up. That was a first for me in 2 straight years of building engines.
I’m not sure what caused the engine to seize but it happened on a very hot day. It might have been of combination of overheating, the 19mm 4 stroke carb slightly too lean, the 70cc kit revving too high up hill with the launch lever pressed for too long, points ignition rotor slipping, or probably an air leak from the old 50cc head gasket unevenly cut by the previous owner to fit the 70cc cylinder… I could have probably saved the cylinder but the piston was ruined.
I got new parts from Treats Friday night and rebuilt the engine with a new polini 70cc kit + head, bigger 21mm 2 stroke carb and MVT Millenium cdi ignition. I also toned down the engine with a smaller rear sprocket, heavier variator weights, doppler exhaust extra spacer, no porting and retarded the timing to keep the temperature down.
During the summer season most air cooled moped engines suffer a lot, especially peugeot kitted engines because of their small fins matching the stock engine’s look. It’s probably safer not to hold top speed for long period of time.
I’ve been riding and breaking in the new polini kit the entire weekend. The bike feels good with less rpms but still plenty of power and hopefully more reliability under any riding conditions, traffic, top speed, hills, high temperature, excessive use of the launch lever, etc…
The bike is ready for take two.
Test run on Hollywood Blvd.
