honda c90 tuning
hi, i have a honda c90 engine wich i have converted from semi auto into a manual. i have a f*ucked 125 lifian engine and im wondering if the gears will fit the c90 engine ?
if not what gears will fit the c90 engine? (im using the engine for road use so ill need something with good pick up in the lower gears and a good top end in the higher gears)
the original gears are knocking and grinding so the will have to be replaced pretty soon.
im also thinking of fitting the 125 head on the honda engine would this make much difference ?
plus i am planning on fitting the piston off a honda c70 onto the c90 as the 70cc piston is domed.
how much difference would the domed piston would make to the performance?
