First I want to thank all posters on this site for sharing their questions and answers that help so many. I have a 1994 Hi Jet S110P EF-NS and i am having trouble with the rpm's not coming down fast enough after the clutch is depressed while shifting. I think it may have something to do with the "fast idle pull off" but i cant find more info. I have checked for vacuum leaks near the carburetor with brake cleaner and propane and found none. I considered replacing all the vac lines but they are still flexible and Seriously numbered. I keep looking and will update my post if i find what vac line pulls the throttle down.
