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.

Yes I have, a 3 to 1 reduction box. Then you need to divide the teeth on the front into the teeth on the rear. add the two together for final over all gearing. That will till you how mant times the eng has to turn over to turn the rear wheel once. Front ones go from 11 to 20 teeth so that's a pretty big range.

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........
