Don...



97k miles sounds like it gets driven on a frequent basis but the question HAS to be asked:

Has the bike been in storage in the immediate past? and do you winterize the bike during the PMS season?



Fuel starts to turn bad after 2 months and can cause build up inside the carb jets. Since the idle jet (or called the slow speed jet) is the smallest jet in inside diameter it's also the very first to be effected by yearly buildup. Sometimes fuel additives will work.... sometimes they won't. When they don't work then it's time to remove the carbs, open them up and clean them out. Obviously it's also the time to check the float settings; adjust if needed and to check the vacuum hoses that are under the carbs and almost impossible to get to if the carbs are in place.



The next suggestion is those previously mentioned vacuum hoses. They are real hard to diagnose and one in particular is notorious to fail.... it's a u-shaped hose that connectsthe intake manifolds and they are directly under the carbs and the rubber mat shield.



Good Luck.

Could be cracks in the carb to intake rubbers.
You need to spray some starter fluid onto them while the engine is running and see if the idle increases.

Sounds vacuum related to me. Hoses, intake manifolds, slide diaphragms.

I think you are going to have to pull the carbs.

Why ain't we ridin'?
