2008 Road King, 27,500 miles, only mod is SE Compensator due mostly to the infamous starter clunk. Now, after a short stop such as a quick fueling, and a restart, I frequently get a kick back against the starter and what sounds like a sprag clutch slipping. From the sound, I assume the starter clutch is a sprag type. Several posts have talked about a tune change to retard start timing. Both the clunk with the old compensator and now this kick back make that seem a reasonable option. I just had a one up ride and got 49.5 mpg so I don't want the "after start" timing changed, is there a down side to the tune change and what might be the typical cost from the dealer? After this happened a few times I checked the starter gear and the clutch ring gear, no damage to either one, pretty well says "starter clutch" noise.
