Thinking of getting a xr 50 for fun and to race in TMGP.. with ysr 50s.. it would be in the unlimited class up to 100cc 4 stroke and 80cc 2 stroke i believe.. could this bike hang with 100cc bikes at the track.. with plenty of mods? thinking of 88cc kit 20mm carb. suspension exaust and manual clutch.would i have a chance in hell of runnin with these guys?

 

with a 124 big bore ull smoke em everytime

 

if you get 88cc you'll want a head and an inner rotor kit and oil pump too.

 

also consider a manual trans.

crankshaft to countershaft, instead of the centrificul clutch

equals 20% more power to the wheel.
