jburner Posted July 19, 2005 Report Share Posted July 19, 2005 I know this has been dicussed but I could find the thread. I had my bike out yesterday and its was really bogging before the powerband. But once it hit the powerband it was crazy fast. What could cause the rough running (bogging) before I hit my powerband. It is not the air cleaner or bad fuel. But, I was only running 91 octane with 20cc domes. Usually in Kansas this has no effect. I'm running 40:1. Any ideas Quote Link to comment Share on other sites More sharing options...
decon Posted July 20, 2005 Report Share Posted July 20, 2005 whats your jetting? if it's right before the powerband i'd say lean the needle out. Quote Link to comment Share on other sites More sharing options...

kenkrieger2001 Posted July 21, 2005 Report Share Posted July 21, 2005 I have experianced this same problem lately,,,,I have no mods on the engine, - I was getting a problem where the engine was bogging out when you hit the throttle,but would idle all day,, - I removed the carbs, cleaned them thouroughly, took out the reeds and miked them and they are right on the spec. - I replaced the air cleaner filter - I put it all back to gether and no more bogging ,except when I left the gas on ,my carbs leak after a while with the gas on. - I adjusted the idle setscrews to 2 turns as the manual says,,,no differecne, tried running them in 1/2 turn no difference its not a terrible sputter,but its aggravating getting the R's up when i want - it was not doing this bfore i experianced the bogging problems. - it seems like I have made a change somewhere with all i have done, any suggestions. - its power is still great when the RPM's get up,,,and if you keep them up, no sputter. - This is when the sputter started.
