This part has occurred before and all dealers tell me it is normal for the '09 and later to do it when the bike has been running for awhile.

So with the oil pressure varying up and down.. could it be a clogged oil filter?

If it were my bike, I'd run a manual gauge to the oil pressure fitting and see if the pressure fluctuation went away. If it didn't I'd pull the cam cover right away.

Another option: A Harley Dealer can check all of this with about 2 hours labor btw....piece of mind is a wonderful thing.

Good Luck!

All the far out responses, when the best thing to do is have the oil pressure checked. An oil pressure gauge screwed into the sender hole will tell you whether you have an oil pump problem, or a bad sender, which is most likely the case here.

Grinding on starting is probably caused by the crap original compensator winding up then springing back, causing the starter to kick back out then back in and grind. The fix for that is 3 or 4 hundred dollars and a new Screamin Eagle compensator.
