All idea’s will be greatly appreciated. My 84 vf1000f has a very annoying resonance thru the fuel tank. I replaced the tank insulators all four. If you add an additional rubber front and rear the resonance lessens. My first attempt was the tank insulators. I inspected the wheel bearings both front and rear. Going so far as changing the front wheel. to verify the wheel bearing. I have not touched the steering head bearing adjustment.
Thanks in advance.
