I recently purchased an 01 Triple Touring; a ZRT 600 with a longer tunnel, second seat and 136 touring skid. This suspension is pre coupling block craze. And like my 2000 zr it rails like crap ( that is until I installed the cat upgrade kit). Im making a crossover/ cross crountry U.P. machine out of it. I wanted the second seat set up for taking my kids on ocasion and didnt want to buy a sled that would hardly get used. But when I mash the gas that old light ski pressure problem appears. The coupling blocks kicked ass on the ZR. Dose any one know if that kit will work on that skid. If not I'll just get a used current 121 and add extensions.
