whirring noise ?

I have an 07 KLR650 with almost 2500 miles. I bought it used with 1987 miles on it last october, last week I changed the oil and adjusted the chain. I now notice a whirring noise coming from where the chain connects to the engine. I hear it only when the bike is rolling with clutch in (probably also present when in gear but engine and wind noise cover it up) no noise when running and not rolling. So is this normal and am i just being paranoid or is it the bearings or something that is going to go boom real soon? I have the doo but haven't installed it yet. Any help appreciated, Thanks.

I'd put the bike on a stand and spin the rear tire to see if it's a guard rubbing or other item in contact with the chain.

You may have the chain a little too tight. Loosen it up a little and see if the sound goes away.

I put the bike on a bike lift and spun the wheel everything is clear and no rubbing. I also measured the chain slack it is about 2 1/4 inches. I think the whirring noise is just from the chain going around the sprocket and I am just being paranoid (first maintenance jitters, afraid I might screw something up) so wish me luck and hopefully it doesn't blow up on me. Thanks for the suggestions of what to check.

Disconnect your speedometer and see if the sound disappears. If it does then you need to lube the speedo cable.

I've also found removing the baseball cards from my spokes helped too.
