I can recreate it on the stand....I can recreate it with all three plastics off.....It's a plastic type buzz(sounds like that anyway)....and.....I think I have it localized to the throttle side of my handle bars...A couple of thoughts:
- have you had the bike on a rear stand and tried reving it to 4500 rpm to see if you can recreate the sound? If you can, things will be a heck of alot easier to find.
- If you can't recreate it on a rear stand, it's probably related to something on the forks: brakes, fender, etc.
- Does it only happen when the bike is under load? In other words, does it stop if you pull in the clutch. If so, it could be related to the drive chain, sprockets, etc. I once used a crappy chain lube and it made my front sproket noisy. The sound came up through the triple area making it deceptive at first. The off clutch noise gone thing tipped me off to it.
- Have you pulled away the plastics and tried recreating it driving or on a rear stand? The plastics have a bunch of possible buzz sources. Plus, if you pull 'em away, you have access to tap on more things with a rubber mallot.
- Is it a high buzz or a low pitch buzz? Metal or plastic?
I'm gonna find this sum-beotch! I'm on a mission..
