av10 21phgb #74 jet. 50cc pollini kit. pollini reeds w/ ninja g3 pipe. i have this problem that i can not get it above 6k rpm's unless it's on the stand than i can hit the power band. my timing is at 1.8 btc. when i sit on it won't go over 30 mph. it doesn't four stroke and it doesn't bog out ( no lean bog).
does the jetting seem lean or rich?
No one here builds le french bike, i need help.
