Anyone have this problem- Last weekend at PIR going into the back stretch if I didnt whack the throttle, just rolled it on, the bike would shutter and miss like it was time to switch to reserve. Sometimes if I didnt really whack it or if I short shifted between 4th and 5th, it wouldnt rev past 11.5K. I checked the plugs, all the fuel lines, flushed the tank (It was clean) pulled apart the shut off valve and float bowls. Everything looks good. Any Ideas? Thankx. Don.
