Engine work

[06 Honda 450R]

how much extra power would i get with a low end cam, new jets, no airbox, exhaust, and race fuel. all this compared to stock enginework with exhaust and jets

no gain will be found with running race gas in a motor without a high comp piston, but if you do all the others you mentioned, you will feel the difference. How much number wise? Not sure. Cam, Exhaust, and filter with open lid should take you to about 9hp gain. Its definitely noticeably tho. I have that done and love it. Not even looking for more power.
