I kind of read through this, on the rearsets and the kicker subject. I didn't notice anybody saying so, but I am thinking that someone, in the past, mentioned using a kicker from a 550F (or maybe 750F? if THAT would work) with SOME rearsets. Just thought I'd throw that in there. It may have just been, that this would work when using setups from other bikes, I don't remember right off.
