Gentlemen, If it was a wheel bearing it would not go away when the clutch is pulled in. Also a failing compensator clunks when it bangs up and down the ramps. The problem is alignment....

Look for something obvious first
1 - check the 2 bolts on the football shaped plate at each side of the frame where the swingarm pivot shaft goes thru. Check for tightness, missing or broken bolt.
2 - Check the front motor mount at bottom front of frame, look for loose thru bolt, damaged rubber, or loose mounting bracket bolts
3 - Check heim adjuster at front motor mount, do not adjust if you don't know what you are doing. look for loose mounting pints on adjuster linkage and brackets
4 - Check the top motor heim adjuster, do not adjust if you don't know what you are doing. look for loose mounting pints on adjuster linkage and brackets
5 - Get it up on a stand and place 2 automotive jack stands on either side of and in front of the front wheel. Tie a string line to 1 stand, pull the string around the rear tire and back up to the front and tie off on the other jack stand. Adjust jack stand positions to place the string so it just touches the high rib fore and aft on the rear tire as high as you can get it. do the same on the other side.
6 - Is your front wheel with the wheel straight, centered between the strings? If no, you need an alignment.

Again, this is not something just anybody should be doing. If you can't find anything obviously loose or broken, check the alignment. if you have time and are willing to investigate, check the alignment. if you find something out of line, get a 2nd opinion at your local dealer.

Thinking thru this, if you have an aftermarket exhaust, another obvious thing would be to look for anywhere the pipes could be hitting something fixed on the frame. The motor and pipes are floating on the rubber mount system in the frame. Your floorboards and brake linkage is fixed in the frame. Confirm the right floorboard is not too close to the pipe. V&H sells spacers to move the right floorboard out a little for their head pipes. If the spacers were not installed the pipe could be buzzing on the right floorboard and or mount transferring the vibration through the frame.

Most of this BUZZ is not a brake pulse. It "buzzes" when sitting still and being reved up to cruising speed.

Well... Embarassed to say i found my vibration. Not compensator, not inner primary bearing, not motor mounts, not crank runout... Kick stand rubber snubber fell out.. Kickstand touching primary going down highway= vibration. Lol. At least it was cheap!
