As some know I had a sideplate break on my POS non O Ring Chain. Jason hooked me up with a DID , that is normally used on a Gixxer 1K 520 conversion. So I think its gonna last on a 91 FZR600. He also did some suspension work for me. I must have spent over an hour in his trailer watching him tweak the suspension and do research. He is such a GEEK :lol: when it come to suspensions. I was very impressed Pleassure to meat you Jason and your lovely lady Vickie CYA @ M-O in a few weeks
