mr.5thou sand:
i ride a 00 kx 500 . the person i bought it off told me about a ball bearing mod and i was wondering if any one knows what im talking about. he said u put a ball bearing behind the rod on the exhaust valve keepin it from over turning the exhaust cam gear deals and obstructing optimum top end flow :?

You may not be able to see this yet, being a newbe. Contact Stewart and tell him you need a KIPPS bolt. Lose the ball bearing idea forever.

mr.5thou sand:

Age old trick. Works well but too many parts to keep track of. And, you will never find the right size ball anyway.

search option up top, search for "bolt-mod" and you will know what you're buddy is talking about too.
