Like the title says, I have two 09 WR450's. One is my supermoto the other is a dual sport. The supermoto has very little bottom end but has a decent mid-range to upper end pull. Compared to my '06 it has no bottom end. I just finished building my dual sport and it feels more like what I would expect from a 450. In fact it feels like it would flat out run away from my supermoto on one wheel. I want my supermoto to match my dual sport's power. They're similarly modded, but different year parts. Here's the rundown: 2009 WR450 Supermoto: Hotcams YZ450 exhaust cam '08 YZ450 exhaust header FMF slip on GYTR jetting kit #50 pilot/#170 main 2009 WR450 Dual Sport: 2007 YZ450 exhaust cam '06 YZ450 exhaust system (header and exhaust) JD jetting kit #50 pilot/#170 main/blue needle Does anybody have any ideas on what I should change? I know that the headers are different, but does the '08 throw off the performance that much? Should I get a '06 exhaust cam? Does the blue needle make that big of a difference?
