Did you get the tire balanced?

Tire/wheel combo should be dynamically balanced, not bubble balanced

Sounds like you got talked into a lot of things you may not have needed. Usually when I put a rear tire on, I just have it spun balanced (dynamically balanced) and put 'er back. No problems yet, been riding 35 years.

Sounds like a balancing problem, or u have n egg in the tyre, both detectable with a wheel balance.

Where did I say "bubble balanced" ?

You didn't say it anywhere, but a lot of motorcycle shops use that and call the wheel balanced... cheap way out. Lighten up bub, just trying to help.
