Squeak/squeal from right-side of engine

I have a 1998 750 and at idle I hear an intermittent squeak/squeal which sounds like it could be coming from the right side of the engine. It's a high pitched sound kind of like a dry bearing being spun too fast. Kind of hard to describe in words but the kind of sound that when you hear it you say "oh yeah"! lol It doesn't make the sound all the time only occasionally and it's only noticable at idle.

Anyway, it doesn't sound like it's currently a major problem but have just recently bought the bike I'd like to make sure I'm starting out on good footing. What I've done so far:

Spline Lube with Moly-60
Final Drive Oil Change
Oil and Filter change (I won't go into the type of oil and filter, lol)
K&N Filters in the stock ears
SeaFoam
Replaced the speedo gear box and cable (It was frozen)
Replaced the battery (Need to exchange the wet cell I bought at AutoZone for a MF)
Coolant Drain & Refill

Still To Do:
Front Tire replacement (plenty of tread but a bit dried out)
Brake Fluid Drain & Refill
.020 Gap adjustment for the pickup coils.

Any idea on the squeak or comments on my plan of attack with the new ride?

TIA for the advice,
Mark

Have you checked the heat shield to make sure they're all tight?

Yes, everything external is tight that I can locate. It definately sounds like something rotating like a bushing or something thats dry. I can't seem to get it to do it long enough to get a good sense of where it's coming from or to try something like pull in the clutch handle or put it in gear.

Thanks for the input though

I just picked up my bike a week ago and I seem to have the exact same problem. Only noticeable at about 1100-1200 rpm at idle. If its a high idle the noise is not present. I am not really sure what side it is coming from though, the weather has been bad and I haven't had time to really dig into it yet.

when is the last time you changes the oil?.. did you use a synthtic?.. is the oil at the right level?.. I am betting its a clutch issue.

That's my thought, clutch. I'm not familiar enough with the internals but if it were a car I'd suspect the thrust bearing, does our bike even have a thrust bearing? lol
