“2007 flhtcui, 1)my primary side very loud whining may be due to chain tensioner, compensator weak spring noticed in neutral and shifting. 2) my transmission very loud whining in 1st. And 5th. Gears. Also loud and noticeable clattering in several gears mostly in fifth. 3) I read on motorcycle talk groups dip stick transmission breaking off have occurred 4) transmission failures occurring while driving . Harley davidson company is not addressing these potential life threatening problems neither upholding there warranty for excessive noises issues.”
NHTSA complaint #10184208, filed 2007-03, 1,000 miles“Excessive clattering noise coming from drive train of motorcycle. Motorcycle has been examined at dealer and was serviced to upload new computer program into engine control module. Drivetrain still clatters and feels as if engine or transmissions shafts are about to break. Dealers say this is normal. Motorcycle does not feel safe to drive. From my reading on internet this is a common issue with 2007 touring class harley davidson. I personally feel this needs to be investigated to reassure owners bikes are sound and that drivetrain is not going to lock up at highway speeds.”

They rode it and said it needed to be broke in, and put 1/2 quart of transmission fluid in. I rode the bike 500 miles and returned the bike on sept. 12, 2006 stating that the primary sounded like a can full of rocks, the 5th gear in the transmission whined so bad it sounded like an ambulance, and the valves were rattling so bad that you could not hear yourself think, and the exhaust pipes had already turned blue. …”
NHTSA complaint #10171068, filed 2006-10, 15 miles“Transmission will not shift out of 2nd gear (up to 3ed gear or down to n) . Transmission will pop out of 6yh gear back into 5th gear at highway speeds. Am afraid the transmission will lock up causing the rear wheel to lock and cause an accident.”
NHTSA complaint #10232228, filed 2008-06, 7,000 miles“Engine knocks and kicks backs, on starting and when accelerating,has been worked on several times, by harley davidson dealer. The problem I've been told is the compensator sprocket and assembly . Through many forums and talks with other harley riders that have had the same problems, the fix to the problem according to people who have researched the compensator is for it to be replaced with the screaming eagle compensator part #40274-08.if this is not recalled or repaired by harley it can be very expensive for the owner to repair approx. …”
