Default Odd Primary Drive Sound

First off hello folks!

I have an odd sound coming from behind the clutch basket (I believe the front sprocket of the belt system). I recently did a pretty good pressure wash of the scooter in that area and noticed after my initial ride after such when I was backing the scooter up in neutral and bike not running you hear the noise that is in the video. I originally thought that it was my starter gear stuck but its not.


Once this scoot cools down the sound will typically go away (usually what bearing and races do when their cold) when its hot its is louder than my old lady.

I also am having a hard time starting this bad boy when its hot, cold no not at all.

Any suggestions? My instinct is that its a bad IDS race or bearing.

Bike is a 2009 FLHX no modifications to tranny or engine other than a thundermax. Bike runs and shifts good, hear a whining noise sometimes when I'm scootin down the road in 5th gear doing about 65mph

Any direction or recommendations would be appreciated.

Its not my compensator btw, noise is definitely behind the clutch basket.


This video was taken with the wheel off the ground and me spinning the rear wheel. The noises a lot louder in the video than it is (audio enhanced in the shop)

Chain looks awfully tight, my guess is the main drive gear bearing, were you spinning the wheel in neutral?

You need to remove the inner primary and check the inner primary bearing, then remove the pulley and big oil seal and get a look at the big ball bearing that supports the main drive gear.
