The problem isn't with the gearing, it's the motor.

You need to put a Honda engine on it, and you'll get 200mph easy.

Have you heard of Black Pipe Exhaust??? Adding that and a rejet alone will get you up to AT LEAST 150mph easy. With a green powerband for your bike I bet it would reach over 200mph. I hear square bearing grease for the wheel bearings make a huge difference on reducing friction for high speed racers like yourself.

I'd recommend welding the stearing stem bearing for stability at those speeds tho.

But if you get one of those, remember to lube your tail pipe regular.
