No gear box, just a centrifugal clutch....probably.
I presume you are using a motor like a 79 cc Harbor freight.
By gearbox I mean a reduction system and jack shaft like a
EZ Motorbike Q matic or the jack shaft mount from AGK.
Putting a centrifugal clutch on the motor and running the chain
to the rear wheel doesn't work because you don't have enough
gearing reduction and the chain doesn't line up because of the
width of the motor.
Your rear sprocket from the 2 stroke kit will probably be the wrong
size for a 4 stroke build.
All this info is right here.......
