Any ideas on how to find the location of a vibration on the GS?  Right before shifting I keep hearing something loose, kind of a metal on metal ringing sound.  Sounds like something is loose, but I'm not sure.  What's the best way to track down loose bolts on the bike?

I usually take the plastic end of a screwdriver and tap it around on stuff until I hear the sound I recognise, and tighten that thing down.  Of course it's a good idea once in a while to find every bolt and screw and just make sure it's tight.  I was missing two bolts from my lower triple once.  Yikes!

If you don't find it and you don't have a critical failure, your other option is to learn to love the noise.

Does this happen at a stand-still as well, or only when you're moving around?  If you can replicate the sound while parked by having someone rev the engine while you look around.   

I'll try the screw driver idea, thanks...


The noise hits at around 5500 rpm's, and only when moving.  If I rev it while parked, I don't hear it...
