I have a 1998 Z50R that I put a Lifan 125cc 4 speed manual clutch motor in. It has the stock 14/37 sprockets on it. Its not very fast but a great wheelie machine. I want it to be alot faster for street riding. What gearing do I need?

Bigger in front and smaller in the rear. That gives you more top speed.

16/32 should do you good. Lots more top end. Usable first gear.
