change the sprockets

[MOTORIDER68]

Yeh sprockets would do it but why are you wanting to change the gearing if you ride in rocks? Or are you just wanting a little more. If your wanting a little more top end, you should just mess with your rear sprocket. Good luck!

Go on ebay and buy a 400ex or 450r rear 36 tooth sprocket for 20.00 dollars. You gain 6mph on GPS. You can use your stock bolts or buy dirt bike rear ones and drill out the old threads.
