For Sale: Heavy duty Doppler pipe for motobecane
$185
New exhaust PUSH spring system designed and tested by Melvin on his Motobecane Av10 polini 50cc ripper.
With that system no more broken PULL springs due to strong vibrations from your kitted engine.
It even comes with an extra set of longer screws if you install the header extension spacer for lower rpms or bigger volume 70cc kits.
The pipes are brand new and come with the ball joint and all the hardware still in the plastic bag.
No more “secret feature”, Melvin’s special springs system is now available for your fast moby.

For Sale: Tomahawk clutch pulley Xtreme kit
$70
Free shipping
Finally a heavy duty kit to replace the Doppler clutch pulley weak stock 6mm shoe posts that bend or break under big power. Soon available at Treats http://www.treatland.tv
Here’s the final version with water jet cut steel triangle brace (installed on the pulley) + machined steel 8mm posts heat treated + 8mm castle nuts + cotter pins.
The thicker base of each post allows the shoes to fit deeper inside the clutch bell for more grabbing surfaces but with enough clearance so the posts don’t rub against the bell. There’s also a special flat section to hold the post with a wrench when tightening the castle nut.
To upgrade your Doppler clutch pulley remove the stock 6mm pins, drill 5/16 holes, tighten the heavy duty 8mm shoe posts with the castle nuts and cotter pins needed for safety. Install the clutch shoes and the triangle brace plate with the stock Doppler circlips.
Et voila, you’re ready to rip!

- BONUS PICS:
Sneak peek at the “Transformer moby” project by Overkill (chassis) and Tomahawk (race engine).
Engine set-up:
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:
Cylinder porting:
Setting the transfers and exhaust port duration at Gr1 moped racing specs + Bidalot variator.
VIDEO:
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.
PS:
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.
My motorcycle frame is a Hodoka Ace 100:
