Ridiculously tight is what it is----with a liberal dose of red Loctite. We just replaced mine and used a three foot 3/4" drive with a pipe on it to get the one off my 2010 FLHX.
Local dealer told me the part was obsolete and wanted me to get the SE upgrade kit for $299, and in addition, buy a new Rotor for the stator bcs the old one wouldn't fit with the SE sprocket. Grand total of $406.00 to replace a $50 sprocket. It was irritating that they would charge so much to upgrade something that should have been a recall.
I called Kansas City HD and bought two sets (compensator sprocket and the cam itself) for a total of about $180...I figure if I can get 25,000 miles out of each set, I'll trade the bike in by then. The tech at HD said that was a bad design, and many of the Screamin Eagle upgrades have failed too.
I hope the starter motor holds up. You really can tell which of the 96 cubic inch HD's are effected when you hear it crunch when it starts. Lots of threads on the HD Forums about it.
