I know about vibes on big single, but the impression is that it gets worse every year (riding on XT already 6 years).
Yes, i have the bar end weights. Install it with the handguard.
I change the triple clamp with usd fork. This triple clamp don't have the rubber bushings and earlier i thinking that vibes come from this.
I already install "grip puppies", brp mount for handlebar with rubber bushings and this not solve the problem. I feel vibes not only on handlebar, but on footpegs and tank.
I'll tighten all the bolts with torque wrench and do the test on this weekend.

I remembered another problem ) I can't adjust the idle speed. Enter in diag mode, switch to rev counter (it show 0). But when i start the engine, dashboard switch to normal state and show me speed and odo. I have the "tired" battery. Maybe this happen because of the battery?
