I was planning on doing a race kit for my 400ex so I can keep up with my buddies banchees. Don't get me wrong the 400ex is fast but when those banchees hit the sand they kill my 400ex. What i wanted to do is a highlift cam, bigger valves, pipe with head pipe. The only thing is that I do not want to bore it out at all, I want to keep it a 400. Do u guys have any suggestions of places to have these things done for a good price. Oh, one other thing is that i do not want to have to buy race gas but i do not mind using an additive.
Thanks, Matt
