good power gains?!?!?!

[zoom400ex]

I was thinking about getting a xr400 cam and a je high comp. piston. Do you thinki would get descent power gains seeing how my 400 is pretty much stock? Do you thinki could keep up witha stock craptor? thankx for the feedback

back when i had my 416 & xr cam and t-4 slip on i was faster than a stock raptor. it made a big difference

with my hig comp. piston, TC cam, and TC exhaust, i can pull about 2 bike lingths on a raptor in a 100yard drag.

i had a high comp piston in my 300 along withthe wb e series and it was a ton faster than before i had the piston. so i thought it might be the same for a 400

i got the all around cam kinda like xr in a way. and wish ida got a race or stage 2 cam. my friend has one and it is totally different than mine. (better)
