I have issues with the bike not idling properly. I can adjust the stop, but it tends to jump from no idle to revving about 2 grand (just a guess, no tach) with a minor tweak of the screw. I was told it was probably something to do with the pilot jet, but cannot locate any information on where to access this part to remove/clean it. Does anyone have any information on how to get at this without dismantling the entire carb? I don't feel like doing that as I have other things to spend my time on like rebuilding the family cottage after the fire.
