people have gotten around the reservoir issue, ive been told and i saw, looked like they had modded the air box, i ddint see any cutting or anything
but for it to work right you need a azis etc 450r length revalved on a GTT link etc.
I did put s LSR link with an elka stage 3 for an 06 up 450r and it rode pretty good , you could feel it needed revalved or something but it was good , lots better than stock.
but i know GTT uses an 05 link and 05 swingarm on the setup
