Howling Noise?
Can anyone identify this noise? Bike runs fine but after riding the bike hard it sort of howls when revved? Doesnt happen all the time usually just after a rough trail riding session or a long WOT run.

yup...gremlins for sure
I'd be concerned if it were bearing whine under load...with it happening intermittently and without load...well, it could be anything...without a doubt it's rotating mass as the whine changes with RPM...that can make it tougher to pinpoint as you don't want to run the machine without the cover as there would be little to no lubrication...
what's the machine?

If you say it happens mostly while in neutral and revved, I think you could probably rule out wheel bearings, drive chain, etc. since it's not moving. Maybe a clogged oil filter/screen is keeping lubrication getting in the right spots?
You could try to take a paper towel tube or a wrapping paper tube and put your ear on it and move it to different parts of the engine to see where it's the loudest. Might help you narrow it down.
