... That's me!
You might be gripping your bars too hard??? i find that when i am tense on the bike, that my hands can get the tingles....
If only it was that easy... but as my old thread tries to describe the handlebars (including engine and frame) has got the buzz... worse at certain revs. and worse when I have been riding for a while (I think).
It has to come from the engine => reving up during standstil (in neutral) increases buzzing.
