Ok here goes....My 02 426 is acting up. It is topping out way too soon, seems like it's full throttle at 1/3 throttle. Classic signs of an air leak and/ or lean jetting right? Well I've tried to find an air leak and can not find one anywhere. Jetting is as follows: Main 170 Pilot 42 (was using 45 for a long time but it had same issues lately plus hard starting) Needle JD Blue clip in #5 position from top down All else is stock in carb. Adjusted the AP squirt and did oring mod today. Didn't help my problem. Bike has Hotcam auto decomp exhaust cam,FMF powerbomb and FMF Q4 (newer version custom fit from a 450). Test rode the bike today, it is FAST but almost too fast and out of control. I've tried all I can think of triple checking everything like timing and such. What am I missing here?!
