I've got what I would describe as an intermittent vibration or buzz on my 07 heritage. It was definitely not there before, its new and sort of comes and goes but is mostly there. I've my hand on every part on the bike to push/pull/jiggle it around and can't feel anything loose.
I had a similar slight "buzz" that was more noticeable at highway speeds at above 4000 RPM.
It really didn't bother me unless I was riding continuously for a couple of hours.
I never could figure out what it was but I knew it wasn't suspension related due to when I pulled in the clutch it appeared to go away.
Since I don't do that much highway riding I just kinda got used to it and it never got worst.
Then I came across a deal on a case of AMSoil 20w50 and 6 qts. of AMSoil 75w110 gear oil.
I put the 20w50 in the engine and primary and 75w110 in the transmission.
The bike has never shifted or ran smoother.
My "highway buzz" is gone so it had to be altered by the fluid change.
I'm not sure if the issue was with the fluids I used or if AMSoil is just that much better at smoothing things out.
Either way I don't care which it was, I'll be using AMSoil for now on.
BTW- I typically used Syn3 in all three holes but I've ran Mobile 1 once before and still had the buzz.
