i just picked up a "sdg" 124cc 3 valve motor! it looks like a nice piece. as far as china motors go anyhow.
i have to spend a bit of time on the wiring and such but its a strong lil beast.
so the 69 ct90 will get the transformation, guy down the road has a kdx80 front end for 20 buck so i my try and work that in there.
now to decide on the 90 motor...should i put it on the st90? or sell it to buy a lifan...decisions
