[QUOTE="mcgovern61, post: 45597, member: 59"] Yep, the idle jets are clogged. The knocking is from your engine being out of balance at idle (left to right) and the knocking sound is most likely the primary chain slapping around (won't really hurt it). If you do not want to go through taking the carbs off yet, try this: Fill your gas tank and leave room to add 8 oz of ATF. (Automatic transmission Fluid...any kind, doesn't matter...Oh...add the ATF at this point) Get the bike warmed up real good and ride for at least a good 50 miles at highway speed. On your way back to the house, run out 2nd gear real fast up to at laest 6500 RPM and let go of the throttle real fast and have the engine drag your speed down. Do this several times. What you are doing is taking a warmed engine that has a good cleaning agent in the gas and creating real high vacuum by running up the RPM and letting go of the throttle which sometimes will suck the jets clean if they are not clogged real bad. Once it is able to settle, you have to sync the carbs again (preferably at idle). If that doesn't work....pull the rack and clean by hand. [/QUOTE]
