Buzzing sound at high RPMs

2019 Views 6 Replies 3 Participants Last post by  StangATX
Hey guys, I've had my R3 for about a month now, got 570+ miles on it. Today I went ahead and lubed my chain (got a rear stand, and it went pretty easily). When I took it off the stand, I swung my leg over the seat, and lost my balance (Stupid pants fell around my thighs, and I messed up the mount). Long story short, I let the bike lay on its side, thankfully, it was on some grass, and I let it down gently. The tip sensor was tripped, and it cut off. Got it back up, no scratches at all (super lucky), but I'm noticing when I get up to around 4k/7k, there's a harsh buzzing sound coming from underneath my seat (sound persists at all rpms above the stated numbers). At first, I thought the exhaust had just come loose (it fell to the right), but that doesn't seem to be it. It does it in all gears, including neutral. Anyone have any ideas what this could be? Was hoping to ride to work tomorrow, but I won't until I figure out what's causing this.

I know the first thing that you may suggest is to take it to the shop, which I'll do if I can't figure it out myself (I AM mechanically inclined, just not as familiar with motorcycles, I'm used to working on cars).

Any ideas?

I would look for anything loose under seat first or something on side you may have broke.

Mine vibrates at those RPM's, are you sure it was not there prior to tipping over?

Yea, 100% sure that it wasn't there prior to the tip. I'll check under the seat tomorrow morning, however it sounds almost like a mechanical grinding, and I can't think of anything under there that would cause that.
So.... update.

I'm a big dummy. Turns out it was my License plate vibrating on the fender eliminator backing. Some adhesive felt circles fixed the problem :)

I have the exact same problem but my license plate is still the paper one. Is your license plate was paper when you've got the noise? I still have the stock fender though... Any ideas?

No, it's caused by the metal plate vibrating against my R&G Fender Eliminator.

For your case, you may want to check to see if your fender is loose.
