Question Strange *&#$%! Noise

I wonder if any of you have heard a buzzing noise at around 4000- 5000 rpm. It just started recently and I can't find it - It's officially driving me nuts. I've been in and out of the headlight bucket a bunch and have sealed that up pretty good. Almost sounds like two pieces of sheet metal buzzing together directly under the tank.

Idea....

Just a thought. Look under the engine & see if your lower, rear, exhaust support is broken. I had a buzz noise & that was it. The pipe mount was vibrating against the frame bracket.

Had that too . But only at idle without my hands on the grips. While riding, I always have a finger on each lever. New levers fixed that. Ha!

That is something I have not checked - thanks XR I'll take a look.
I generally ride w/ my hands on the leavers so I'm sure it isn't those but thanks kingbrian

I vaguely recall reading a post about the horn being loose and buzzing at that rpm. It may have also included the radiator shroud. Check those out.

I have the same buzz of death. My headlight bucket is a rediculous mess of insulation foam and electrical tape, that think couldn't rattle if it's life depended on it. I have also lifted the tank and put insulation foam all over the top, and sides of the frame tube to no avail. After this, I have come to the conlcusion that it is the cooling fan, I plan to mess around and try to fix it but it might be unfixable, I know this because of this thread: on Hornet's Nest

I think that was the thread I was thinking of, . Not the horn but the cooling fan. Hope that helps.

Dr. Razor prescribes Satos. 2mg.

It's a fool who looks for logic in the chambers of the human heart.

i remember someone having a buzzing sound under the tank a long time ago it turned out to be the ground cable that goes from the tank to the frame was in a bad spot and vibrating.

I've been off the bike a lot lately so finely just had time to go through it again looking for this buzz. I think I found it, one of the rubber bumpers on the side cover was gone and metal upon hard plastic buzzing ensued. I'm pretty sure it was the culprit but will know more this weekend

Here's a different thought... Do you have a keyring for your bike or just the key itself? I had a buzzing that drove me muts for a while until I realised that it was the key for my heltmet lock buzzing against the handlebars. :shrug: Just a thought.

I did the flapper mod as well and neither felt nor heard any difference at all. Not sure what it's 'supposed' to do, but since it didn't change anything I just left it that way. Maybe someday it'll surprise me and do something when I least expect it

Ok, back on topic now...

Are you talking about the gray side cover or the black plastic one?

My headlight was contributing to the buzzing noise until on of the mechanics at my shop put plastic washers on the mounting bracket. That really reduced the noise, but the bike just has some extra vibration in those rpm ranges. You should see my flyscreen shake..........

mine was coming from the chrome headlight rim. I put some foam rubber between it and the bucket, cleared it right up.

It was the plastic one, the bumper missing is the one tucked back underneath the tank, at the front of the side cover. If I wasn't so lazy I'd go out and shoot a photo

Thats alright, thanks, I am going to check mine when the temp in my garage gets reasonable again, probably 2 months before that happens.
