Take the wheels off and check the balance. There was another guy on here that raced after getting new tires mounted and the tires ended up spinning on the rim because of the grease they put on when mounting the tires, thats what threw off the ballance.

110 is against the law there sonny boy. 
definately the tires. if you're going to be hitting over 100 often, makre sure they balance them to excacts. most specs allow for one side of the wheel to be a 1/4 ounce off since you'd never feel that going anything under 110

Re: Shaky Rearend after New rims
Are you sure the rear wheels seated fully on the hubs? Sometimes you run into a problem fitting the newer model wheels over the over-size rear hubs on the earlier year 4th Gens. That would explain a side-to-side wobble.
If they aren't seated all the way, you might have to enlarge the center holes in the wheels slightly.
