05 700 RMK wont hold RPM's when climbing it starts out good but 1/2 way into a climb it will drop from 8100-8200 to 7600-7800 RPM when I hit the noss it picks back up for a little bit then drops again. It has the SLP performance package, SLP performance porting, SLP performance single pipe, cheater head, v force 3'S, SLP air horn, gutted air box and everything else that goes with the performance package. 7 tooth Avid exvert drivers, 2 inner 8'' rear wheels, 155x15x2.4 track, 19-42 gearing, 10-60 weights, SLP blue yellow primary spring, team secondary clutch, red black spring 50-45 helix set at 60-40-36. light weight mesh hood, light weight rear suspension, boss seat, and a few other light weight parts. Ive tried 68g mtx weight and different rivets 10-64, 10-62, 60-38-36 helix, jetting, new belt, new springs, the clutches are clean, rollers are good, the track turns freely. Egts run around 1200-1250 when in the 8s then down to 1000-1100 when in the upper 7s rpm. I ride in Island Park 6000 to 9000 and Cooke 9000 to 12000. Any help wold be greatly appreciated. Thanks.
