I am starting to suspect a leak in the carb boots. The vacuum line is new and I have plugged it with no change in idle speed. I heard someone mention spraying starting fluid, WD-40, Seafoam (I had to include this) on the boots while the bike is running to see if the idle speed changes. Any ideas on this method?
