    Proof that a friction drive bike can look cool. The exhaust rocks.

    Thanks guys!!...The pipe is made from a Yamaha YZ 80 aftermarket expansion chamber..I got from a motorcycle salvage shop for $20....

    The motor is a Cag stage 3 (54 cc) I ported the intake manifold & has triple stage black widow reeds.....Also the exhaust has been port matched...This thing should fly!!.The power output will be close to 5 hp @ 12000rpm..My goal is to cruise easy at 25-30, and get it on at the track...Aka.. vacant parking lots.. 50 plus mph !!!...

    Default Friction Drive

    Hey Thumper, Thats the first friction drive I've seen that I think looks cool. I've always been the "gotta look like a motorcycle" guy. I know it's not street legal but I would put on a 49cc sticker, try to keep it under 30, 35mph and rip up the streets with that bike. Please don't take that as GOOD advise though, Thats just what I would do. Good job, VERY COOL.

    Hey HS...Thanks!!!...As for the rack mount...It is STRONG ...It has two cross braces that tie the rack together, and the rack is fully welded !!!...The rack is built with 3/4" by 1/8" steel...

    Ok...I got the bike running on Easter...The V drive roller works awesome!! I cruised it nice and easy...still breaking it in. I need to tune the carb and work on the clutch. The clutch engagement is too high..As for the performance so far..The bike does 31mph at half throttle...At little less than 3/4 throttle it hit 38mph, thats as hard as I pushed it....When I get it broke in and tuned...I will put the hammer down, and see what she will do!! Oh yeah...It sounds mean !!!
