Screamin Eagle big twin compensator

I have been trying to solve a starting problem on my 09 Super Glide. Starts fine when cold. Starter raises hell when engine is warm. It has a hard time turning the engine over and takes 2-3 tries to get it started. Had the starter checked out. (good as new) Replaced battery, cleaned all cable ends, cleaned fuse connections, new premium gas, new plugs, same problem. Talked to service manager at the stealership, and he told me I need the Screaming Eagle big twin compensator. He also said the later models have the compensator already just because of this problem. It will cost around $500 installed. Seems like maybe it should be a recall item. I'm not exactly sure what it does. Is it a further gear reduction between the starter and the ring gear to allow more starter torque? Has anyone had this problem and added a compensator?

The comp sprocket absorbs shock load transmitted from the crank shaft thru the drive chain to the clutch assy. .
In 2006 H-D changed the design of the comp sprocket from a muti-piece unit to a welded one piece unit incorporating the alternator rotor .
The welds were breaking in the early comp sprockets so H-D authorized the dealers to replace the units with the heavy duty Screaming Eagle comp sprockets .
Now all models are fitted with SE style comp sprockets .
H-D authorized the upgrade on a fix as fail basis , not a recall .

Fixed

The starting problem has been fixed. My stator was burned up as well. The new S.E. big twin compensator was supposed to be the fix, but it may have been a combination of both.

Good deal.

Running lights

The lights are original Harley Davidson and I bought them at the dealership. About $ 400 with the brackets. They have a thumb switch so you can leave them off. I never leave them off, but they turn off when you switch to high beams. Easy to install!
