Rattling noise at idle.

Ghis,

The UK member on the UK CB board that had the noise pretty bad had his cam chain tensioner chaned out, I think. At the time, both the dealer and Honda were pretty sketchy about the whole thing.

I can search around for the thread if you want.

If it's not to much, that'd be great.

Normally, I would be telling you to check your carbs to make sure they are in sync. The rattle is caused by an out of sync carb, which in turn makes the clutch basket make all kinds of noise. But this is a CB1100 we are talking about. I would not worry about it, as I suspect it has something to do with the syncro's in the clutch basket. Does the rattling go away with the clutch lever pulled in? If so, it's in the clutch basket and I would not worry.

Also, sorry to debunk some of the oil theorists but changing over to synthetic oil or changing oil weights will not change this effect whatsoever.

Pulled the clutch in, and it's still there. Even put in gear (on center stand), and let the clutch out, and it's there with the wheel spinning.
