There are many sources of vibration.
My 1300 has a peak at 52 MPH in 5th.
With stock exhaust no peak noticed, with jc whitney mufflers it was horrendous, with HK it is there but not bad.
Metz ME888 tires caused a buzz at 27-28 mph on de-cel, buzz was from rear shock covers.
I had a major vibe in right handlebar grip for one summer, right hand got numb. Never happened again.
State of tune can affect vibes, lean/rich.
Is this new?? Do the Ground fix, tighten battery cables.
Check vacuum hoses. Cracks/splits will lean the A/F.
