ok so i have come to where i am having a hard time figureing a few things out and i do have some questions. first i was wondering about some heavy duty wheels for a 20" inch was thinking some BMX wheels 36 spoke double wall rims but have to have 3/8" axles, was wondering if anyone knew of a good set or if anyone made custom wheels due to i would like to i would like the rim and hubs to be black with white spokes and chrome nipples, and my next issue i have come to is brakes. I would like to use disc brakes on this project but was not sure of clearance or if there was a set that would be compatible with a 20" inch bike? i dont want to go and buy the disc brake set just to find out i cant use it, so was wondering if anyone else has attempted this. My last and final issue is an exhaust. being that its a 20" inch bike im having an issue finding anything useable on my build due to everything i have tried hangs down to low and hits the ground. i would like a decent expansion chamber with high flow muffler to increase the power, any info to help with these isues would be appreciated.
my last few questions are if i do use the kx65 expansion chamber and pro circuit exhaust i was told i would need to tighten the clutch springs and have the cylinder ported, i was planning on buying a ported cylinder soon and the diamond high compression head and ngk plug and jaguar performance cdi coil so thats all taken care of, but i could not find any info on how to tighten the clutch springs and was told to ruff up the clutch pads slightly with some sand paper is this true?
and last was told to lock tite all the bolts on the motor and upgrade to stronger engine bolts, are the bolts that come in the motor not strong enough already?

A 70s Stingray is a tight fit for a China Girl engine, but they look great. For strong wheels, I would just buy a used kids 20" multi-gear mountain bike from a yard sale. It won't cost much, and you could use a lot of parts from it.

Ok I have a big question about this build, I was able to spread the rear of the frame apart to allow for a 5 speed rear hub and installed a detailed and shifter and shifter cable, now my big question is does anyone know if I would be able to install a jackshaft kit on my 1973 schwinn sting ray and if so has it been done and does anyone have any pics. I been looking into this and have seen alot of other people using them but could not find any on a 20" inch bike. So please any info on this would be a great help. I was looking at the sick bikes kit bur again clearance issues have become my concern and honestly I do not have the $145 to waste on something I am not going to be able to use. So please help.
