My nephew has a 2009 Dyna Glide fat bob with a hydraulic clutch he bought last year. Rode it all season last year, no problem. This year,after about 50 miles or so, the bike starts creeping at stops in 1st gear. Can't shift to neutral so has to shut off bike and then he can shift to neutral. After starting, he can't get into first, so he has to start in 1st and it's pulling. Dealer has flushed fluid and bled, then 2 weeks later he brought it back in and they bled again. Mech said fluid had absorbed air and moisture and had bubbles. After bleed, same problem so they went over entire clutch system and said everything is good. They said the clutches need bleeding after winter storage because the hydraulic system is vented. Never heard of a vented hydraulic system in anything. Also they must be incompetent at bleeding if they have to do it multiple times in a season. Harley had recalls on hydraulic clutches on years after his bike and his isn't recalled. Problem was some soft parts were reacting with dot 4, and generating bubbles. Now they're telling him it's his aftermarket exhaust heating something on the right side of the motor causing the clutch fluid to boil, and now clutch has to be rebuilt, and a heat shield added. Hard to tell since i can't actually see bike, but it looks like everything clutch related is on left side. He hasn't changed anything, so all mods are as he bought it last spring, no problems last year, and he rode a lot. Any ideas?
