I am just curious, how long has your new front tire bent on your bike? I replaced mine about a year-and-a-half ago and had a real bad shimmy in my front end. I did everything to my bike. Took the screen off, took saddlebags off, readjusted headstock bearings for five times. Took the wheel off and had it rebalanced. Come to find out it was the new tire I had put on the bike. It was an Avon cobra. Call Avon up told them the problem and they took care of it.
