07 Vibration Revisted

I posted last year on a vibration problem. Its noticeable with the engine is running and gets worse while the bike is in motion. Still no solution. This all began after changing the oil and filter, adjusting the idle speed and adjusting the chain tension. Since the original problem the bike has new tires, new chain, and sprockets. I even changed the oil and filter and sent the oil off for analysis. No apparent wear in the engine. Which leaves me to the idle and tuning. Bike only has about 6500 miles.

I guess I answered my own question while typing....

I am thinking of going to an independent service and race shop to have the air and fuel systems checked out. The dealer was decent but no help.

Sound like a good plan?

Please define vibration? The VFR definitely vibrates under me as the rpms increase. It's not an I4 so that is to be expected.
Can you still see objects in your rear view mirrors?
Are you referring to wheel vibrations or engine vibrations (I assume engine based on your post)?
Have you balanced your wax unit? That is known to cause rough vibrations during warm up and possibly a rougher ride as well.

OK, I give. I have searched, but not come up with anything about a "wax unit." So what the hell is it?
