I am not getting the Wheels, but I still don't have the feel to even suggest what changes might help. Heck I am not even having problems with the BTs that aren't rider error. I wish I could, but I don't know what is my problem and what is the bikes problem. The way it was setup at Tally, I can't fault the bike since I am sure that everything there was all rider error. I like my bike to be solid, when I have had the rear softer I feel like it wallows (which might be rider throttle or bar input). I agree Suspension is the most important part of a race bike.... And I am not trying to change geometry between sessions I don't have the luck, temper restraint, or patience (Dislocated my finger at Tally punching the trailer ramp after several problems just trying to get my lock nut loose on the rear shock). With all this, do you really think I will be able to tell the difference in different tires?
