60 days left before the 1st SoCal moped/motrized bicycle race April 7th 2012 at Grange Track, Victorville.
I should have enough time to paint and reassemble my 50cc race moped with no fairings this year to blend in. I’m the only dedicated moped racer left in Southern California and I’m starting to lose the motivation to compete. But I’ll try to attend and support the event organized by Neil and race against the motorized bicycles.
We don’t really have any motivated racers or fast mopeds left in Los Angeles, but if you want to come and play with your moped or just watch the race, mark that date on your calendar. The track is only 1h30 min away from LA and 60 days should be plenty of time to get your bike ready.
There should be 3 or 4 events this season with scooter, moped, bicycle classes and maybe some drag racing. This year I’m not looking to win or prove anything but just have fun on Saturday afternoon with other racers on the track. It’s always a good experience to share and learn new riding or tuning skills. The fast electric bikes are fun to watch too.
For more details, check out Neil’s post on http://www.mopedarmy.com forum moped general discussion:
The world fastest mobility scooter 70 mph (normal speed 4-8 mph)
Puch moped rally in PARIS:
” Breda-Paris Rally on 50cc vintage Puch mopeds. It shows friend fuckers, hardship, the odd biker love, karma & harmony/discrepancy. Rules? What is the final rule? Money: to spend it on a thrilling party. Why Paris? Solely to ride. In Paris.”
That video says it all. No matter what country or type of vehicle, it’s always been about speed.
Tomahawk ripping the streets with G1 50cc race bike for the monthly test ride.
There’s no clutch pulley but I’m lifting the launch lever with my foot at each red light to keep the idle by making the belt slip on the variator. The bike is really flying, there’s plenty of power and acceleration to test an even smaller rear sprocket for better top speed. The pipe can still be modified to gain some extra rpms and power but I prefer to keep the engine reliable. I wish I could have some moped racers to compete against on a track.
Back from the test run, good combustion with a chocolate brown spark plug and still room to lean out the fuel mixture for better performance.
Motobecane av10 race moped with stock engine cases, stock 2 petal reed valve, 19 carb, stock cdi, old 50cc Bidalot kit, enjoy the ride…
Here are some pics of a 1991 Bidalot G1 50cc vintage racing kit (not replica version) with stock cases, stock intake manifold, Bidalot crank, Dell’orto 15 carb, Champion spark plug, 9.5 hp @ 10,000 rpms.
I’ve just ordered some new moped race fairings from http://www.treatland.tv for a future fast motobecane av10 50cc Gr2 race bike project with 30mm Paioli adjustable hydraulic fork, stock engine cases, 21 carb, malossi or polini 50cc h20 kit. Thanks Treats for shipping them so fast!
The engine feels just the way I anticipated it. I can tell by ear that we’re close to 11,500 rpm. Not bad for a beat up 50cc Bidalot kit with an old nikasil. When I looked at the small ports I never thought that kit could rip but I increased the port duration to Gr2 specs and it worked. I was afraid to lose some low end power with the new port duration but it didn’t happen, even with a standard pulley. I can’t imagine how good the bike would feel with a clutch pulley. In general, Gr1 set ups are not as powerful as Gr2 or Gr3 but have more torque.
Overall the bike feels good, not quite as powerful as my Peugeot 103 Rcx 50cc h20 but close with more torque and way lighter. The downside is that it’s an air cooled engine so it won’t stay as consistent during the entire race, especially if it gets hot in the desert.
