Looks like your ready for some new tires,lol. SP4L has a set off Guetto Wheels w/ slick tires for $55, and $20 S/H. The ones on my avatar L7 bike. You need to buy bearings for $10 or use the ones in your old rims. and your can use your axle & center bearing spacer on the yellow bike.
They come with front & rear rims, tubes & tires on rims ready to Fly. Alot cheaper than buying piece by piece.

those are actually still good tires the wear holes are virginal.

Must be all the cement dust on the tires.

probly dust from the bobchop build. i worked most of saturday getting frame straight and figuring stuff out.
have you mounted a dirt bike gearbox on a cag? ifso whats needed for final drive regarding gear size/tooth size on output side. also whats the offset from the case to the drive sprocket?

Pocket dirtbikes have bigger 10" rims/tires and the gearbox operates at 7:1..Gearing should add another 4-5:1 for a total offroad gearing of 11-12:1......With cag rims/tires you can run a 17tooth on the countershaft easily.....Most cags/gprsr's with stock gearing operate at 10.8:1 or 9.5:1 depending if its 6/68 or 7/68 gearing

All gearboxes have different offset specs and can be mounted a few different ways........
