Mine was squeeking/vibrating too, it was the windscreen - where it meets with the batwing it was squeeking. I tightened up the bolts a bit and it went away.

 

Get cha some silicone and spray it on the rubber muffler hanger on the rear of the bike. If that cures it, it will only be temporary. I ended up taking the saddle bag support off and put it in a vise and crushed the steel that holds the rubber thing a little bit. If it in fact is the hanger, try my suggestion. Slightly crush it on the top and bottom AND on the sides. Not too much though! You want it to be tighter, but still allow the flat steel piece to still slide some as it needs to be able to move to absorb movement of the pipe. Might want to take that chrome cover off and see it that is the culprit...

 

It's your floor board. The front floorboard mount (on both sides) has a 1'8" of clearance between it and the bracket mount. I used a nylon washer wedged between them and held it in place by the mounting bolt. Does that make sense??? Anyway - look at the front attachment and you'll see what I'm talking about. Do both sides - because the other one will do the same thing eventually.

 

Ok I just realized its not wheel bearings since I can hear it when I'm at a red light.

 

Mine was squeaking like crazy too. And it came from the same spot as you described. I narrowed it down to the upper front motor mount. The one with heim joints. Took it off, cleaned it and lubed it and the squeaking went away. Just to see if thats your problem, just spray some lube on the joints and work them by hand a little, is the squeak stops, remove, clean, lube and replace.

 

same thing happened to me at 1,000 miles pulled and blue locktite them all all of them were loose

 

Check your side covers to see if one of the grommets popped out.

 

I have the same noise and I found that if I push down on my left muffler the noise goes away. I just wrapped the baffles and the chirping started. So in my case I think it may be the hanger or the bag but I still haven't stopped riding long enough to find out

 

had a hose clamp on the exhaust sheld touchin on the tranny cover drove me nuts till i found it.only touched when running it showed a little clearence when not running.

 

Saddlebag latch......metal to metal.
