Need a diagnosis....
A 2007 Street Glide with less than 5K on odometer. Has sat-up for about 6 weeks. During a short ride while stopped at a traffic light with the bike in neutral, a loud metallic bang x1 is heard coming from the motor/drive train;there is not skip or hesitation in the motor and no backfire; the bike easily goes into gear and drives normally. Alittle while later during the ride, the scenario repeats itself (stopped at light, drive train in neutral) - loud metallic bang x1.Any ideas? Stiking valve? You know the dealer won't even look until it is fatally broken. Fellas, I would appreciate any help with this.

Reading another thread, it sounds like it could be a rod ("a gorilla hitting your engine with a five pound hammer"). Appreciate your thoughts.

RE: Need a diagnosis....
I have an odd one that I hear at different times. Usually, I am moving but have heard it when sittig still.. Not an exhaust bang. But a sound as if something metal were dropped on a fender, but more tinny sounding. I think it is is the driveline though, as I am thinking it happens when releasing the throttle and pulling in the clutch.

RE: Need a diagnosis....
lots of possibilities, you will have to supply more info, but....
Check the compensator. A loose compensator could have the same side effect. Banging as it drops back into mesh.
Otherwise how long does it last?
Either way bike is apparently under warranty for another year.
Ride it hard close to home and see if something fails. Then let the stealer have it.
