Primary Noise

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.

Paul

It is probably compensator/inner primary bearing related.

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

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.

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.
