I have an early 2009 RK with 23000 miles on the clock. Just got back from a 3000 mile trip and I seem to have developed a noise in the primary.

Symptoms same hot or cold.

Clutch pulled in and it's quiet, but release the clutch and it sounds like spinning a rough bearing, a sort of light scraping grinding noise. Pull the clutch in again and after 2 seconds it stops.

I think I know what the problem might be but before I decide to crack it open I'm seeking opinions.

Any information is gratefully received.

It is probably compensator/inner primary bearing related.

 

sure sounds like the inner primary bearing. about the same number of miles when my first one went out. 2nd one at 35,000 miles.

 

What happens if you're in gear at standstill ? The IPB doesn't turn anymore but the clutch bearing does ...

 

Inner primary bearing.

Don't know if the above link will show my IPB inner bearing race but its shot. Badly scored.

Sorry for silly question but how is it removed from the shaft.

 

Ok looks like the photo worked.

I have checked rotational runout on the shaft and its about 1 1/2 thou of an inch, I think service limit is 3 thou.

 

Go down this page to the mainshaft bearing race tool. That is what you need for removal and installation. Georges tools are expensive but super high quality.

sounds like inner primary bearing--might as well do the compensator while you are at it.

 

Funny enough the stock item looks fine but I've ordered the SE comp while I'm in there. Hopefully it will all arrive next week and I can button her up Saturday.

No idea why the bearing has picked up like that, never seen it before.

It sounded like s#|t when I turned it by hand, hopefully I caught it before it toasted anything else.

Guess I was lucky with that scoring it wasn't going to last long.
