Its a crap shoot with this Bike

[cbfan_imp]

Being a retired aircraft mechanic I was sometimes tasked with fixing vibrations/"buzzing" at different power settings. Nine times out of ten I would find chaffing conditions in the engine compartment. Check your bike out to assure there is no metal on metal contact anyplace. I have an FJR and installed engine guards with highway pegs, at installation I didn't catch the peg bracket was chaffing some plastic.................at certain speeds I would get a minor buzzing sensation...........repositioning the bracket cleared it.
