Need Help with vibration issue.
Ok guys here is the deal. I have noticed that when riding my 12, when the tank gets to about half full, there seems to be a pretty noticable vibration throughout the bike. I can feel it in my feet, body, and hands. But when it is full of fuel it seems to go away, or at least get minimal. It almost seems like an engine thing, but why would it get less with a full tank of gas? This is starting to worry me, as I really dont want an internal engine failure or a transmission failure. Any help would be appreciated.

By the way, my bike is a 2000 ZX12 with only 6800 miles on it. New tires front and rear, chain is in great shape, clean and lubed.

Is the rubber damper at the front bolt in place. If the tank is bolted solid to the frame, you'll feel it.

Sometimes the chain can induce vibration if it's old, or bad links (strecthed/damaged).

how well are the tires balanced?
is this sitting still or moving?
some guys get lazy whilst balancing tires.. 
just an idea..
the added fuel will affect the dampening of vibration a good bit tho..
