After my install, the primary is less noisy when first starting but when everything gets hot and this is a hit & miss thing, when you start it again, there's a lot of noise (whirling sound) coming from the primary area. Pull the clutch in, noise is still there, so I can't blame it on a bearing issue.
Running the first edition SE Comp & HD Formula +.....Like I said, only happens after bikes been run a long distance, shut off and then restarted (doesn't make any difference if it sits 5 minutes or 1/2 an hour) but it doesn't happen all the time...
Any thoughts????? If it was the IPB, wouldn't be noisy all the time???

Put one in my '09 this past summer, But it was too late...the IPB was alrady toast. My primary was always noisey since the bike was new. Had a new IPB installed and now with the M6 still in there, there's no whirring noise and shifts better. I wish I'd installed when new. For aorund $100 cheap insurance maybe....

Correct me if I'm wrong but according to my parts manual the outer diameter of the IPB sits in the bore of the clutch basket and its inner diameter connects to shaft of the clutch hub. So when the clutch lever is released (plates closed) the IPB's OD and ID have no differential speed. The IPB only turns when the clutch plates are freed.
If you incriminate the IPB you should be able to feel its play through the clutch adjustment port by rocking the clutch basket from front to rear with your thumbs; the clutch plates need be separated to do this.

Installed one last month. Found my primary chain as tight as it could get. Primary is much quieter now. Wasn't looking for anything more than to get rid the ratcheting tensioner. Like others have said--cheap insurance. As far as install, simple, just use the service manual and replace the screws correctly. JoeSDE

So, its this split cylindrical bearing we are talking about:
#9231 Outer race and roller cage (6) that sits in the housing
and the (14) separate inner race #34091-08 fixed to the gearbox input shaft
This unsealed cylindrical bearing is designed to resist to very high radial load but is subject to abrasion and requires thin oil.
With the SKF viscosity calculator I find similar bearings require a broad range of viscosities to operate between +5 and 100°C and at engine speeds from 1K to 6K RPM (500-3000 RPM on the input shaft). A 10W30 seems fine for the IPB but is not thick enough for the compensator and for the bearing inside the clutch. It seems we're bound to loose one or the other(s)
Coming back to the original topic IMO the Hayden tensioner will better protect the chain than the heavy duty cylindrical IPB. As many said, its a cheap insurance.
