That was my point, I don't think doing just an intake swap will make a noticeable difference @ all. Reason I say this is over the summer I had Steve Knecum build my engine
When it was all said and done I gained 25+HP. I used Yoshimura stage1 racing cams, they are not huge cams by no means but I have 2 believe that they would provide more HP than a intake cam swap. With that being said Steve gave me a break down of the HP I gained and where it came from. He said I probably gained 5HP give or take from just the Yosh cams and Steve knows these bikes inside & out!
So....if I only gained 5HP from the Yosh cams how much do you think would be gained from an intake swap?? My guess is less than 5 and who would be able 2 tell the difference from such a marginal gain. A mod like that has 2 be done in conjunction with other mods & improvements like I stated so these small gains add up and provide a substantial improvement in HP
