I think i was wrong about one thing.......it's hard to detect, but i believe it DOES do it with the clutch pulled in. So if i'm right about this it much be the Wheel/tire/chain. But it's faint by comparison, so i suppose the engine putting a load on it makes it much more obvious. Tonite i'll finally have time to try Pat's alignment method. Even tho the notches are where they were before the tire swap i'm wondering if the adjusters somewho got elongated where the axl goes thru. I noticed they looked out of round so i'm thinking they get that way normally and is probably what causes the notches to be off. Anyways, i'll check it tonite. If that doesn't work i believe i'm going to buy a chain because i don't know what else i can do.
