I don't have this problem, but it also sounds like you need to synchronize the carburetors and open up your pms some. Out of synch carbs and a lean condition can cause a sticky ideal. Take a look at your plugs, that will tell you if you have a lean condition. The plugs need to be a tan/gray color.I have a 99' 1100 custom. I runs great through town and short trips. After cruising at highway speeds for twenty miles or so, the idle speed is unusually high. It almost sounds like a lean condition. Any one else have this problem?
