tire size v. suspension adj. question.
I recently got a set of Dunlop 209 GP's, they are great, the front is stock size, but the rear is a 190/60/17, my bike was set up by Race Tech for the stock front size and a 180/55/17 rear, I had Pilot Race tires before. So my question is with the new tire the back feels really big and I think the suspension should be adjusted for the new tire size, what would be some things to get started with? My thought is the rear shock needs some pre load taken off, and nothing in the front, but i am not very good with these new style suspensions, thats why I had Race Tech do the bike before. So any ideas or help would be greatly appreciated.
