HELP! New and odd motor noise! *UPDATE*
logged about 1,200 miles on our memorial day trip this year. About 800 miles in on a rather hot day (95+) my bike started to make a somewhat loud, high pitch squeal/whistle. (really sounds more like a whistle but i might be wrong) This is the 1st I have heard this noise in 4,000 miles and it does it all the time now. It is very noticeable at idle and deceleration but much better when i am in the throttle.
Stopped at a dealer out of state and they advised me that it was ok to ride but it needed a closer look when i got home.
The bike is going to my dealer later today but I was hoping to get a head start on what this may be.
Thanks!

Sounds like the primary chain is overtightened. Happens with auto-adjustable primary chain tighteners.
OR:
It could be a drive belt unless you have a chain final drive. Alignment issues or excessive wear can cause this issue.

You didn't say where the high-pitched whistle/squeal was coming from, but you might want to check your fuel pump. Mine makes a high-pitched noise, sometimes more noticeable than other times, but I wouldn't call it "loud". From what I've read on the forum it's not hurting anything to run it like that and I probably have some time before it actually causes a problem.

+2 Don't take chances in case it IS a bearing.

To me it definitely doesn't sound like a bearing, it honestly sounds like a vacuum leak on a car. Im not really sure why I said squeal, I guess it's just hard to put my finger on the exact sound it makes.
It sounds like it's coming from the front of the motor, doesn't appear to be coming from the primary or transmission. It also makes this noise right at startup while sitting in N and idling. Someone on another forum suggested a blown head gasket. Hopefully the out of state dealer didn't give me bad advice saying it was ok ride home (about another 300 miles after they looked at it)
It goes to the dealer in a few hours after I get out of work, hopefully it is something stupid...

UPDATE:
Well, the dealer took a closer look and found that the "Induction module cap plug" was missing. It's just a cheap rubber elbow plug that happened to come off the bike. This is buried behind the Throttle body.
They were able to find it in about a half hour, replaced it under warranty and had me back on the road in about 45 minutes..
