need more POWER

[motown]

HEEEEEEEELP!!!!! cant keep up need more POWER I rode my buddies 450r and dam is my bike slow I have a prettymuch stock 400ex fmf slipon uni filter I have been looking at bigborekits and cams I was wondering what would give me the most power without loseing my reliable bike any input would be great thanks:confused:

My suggestion is the 416 kit, with the 11:1 piston and Hotcams Stage 2 cam. I think that will help you out. I think the 416 gives the best overall when reliability is an issue. 11:1 pistons will allow you to use pump gas which is nice. Gearing will also help you keep up with your buddy. I am unsure which aspect of keeping up with your friend your having.

If your budget allows--stroke it.
