It’s taken all summer but I finally got my bike to where I want it! It really kicks butt now. So much trial and error and a lot of help from members of this forum so a big THANK YOU.
This is what I’ve done; let’s start with the motor- it’s a 66cc silver jet, I have replaced all the hardware with grade 8 studs and socket cap bolts throughout. The cylinder head was cleaned up at the ports; the intake and exhaust are about a 2mm wider due to the removal of the casting ridges. Gaskets all have been port matched. A NGK b5hs plug (it’s cold here in Washington) I have a manic mechanic billet high comp. head and tapped billet intake. Dual boost bottles (I know the duals are mostly for bling) I had also re-tapped the manifold port so the fitting is angled towards the head. The carb is the knock-off dellorto with #68 jet. The control comes from a billet aluminum pit bike throttle. it’s being fired by the Jaguar cdi and the exhaust is a modified pit bike pro-jet pipe. The drive train is the MM hub adapter with a 40 tooth gear and a D.I.D 415er chain. I got lucky and was able to angle the motor so I have perfect chain tension with no tensioner. I have the push button clutch and am riding on Continental Tourride 1.65 street tires and a HD rear axle. The cranks are the wide ones with bear trap pedals. The fuel is helped by the brass free flow valve with 32:1 super M ester based synthetic oil. I’m not going to say I’ve got some crazy top speed out of all this. But I’ve got to say that low end torque and acceleration is AAWWSOMME.
Anyways, Thanks again and Ride Safe…

. I think the only future mods I will do for performance will be the expansion chamber and smoother tires, maybe port polish. To make it sorta a better ride I should get them wider cranks you have, the ones in this bike are a joke an seemed to be made for a kids leg. Did you buy the crank and foot pedals online or locally? I would like to purchase some in the future, my dog chewed on mine.
