My 1990 sn is pretty rough shape as far as a few drivetrain issues. I have a friend with a vxr 650 that was wrecked in the 90's (glass issue only) and has a super low use drivetrain. Is it worth it to swap the stuff from the vxr to my superjet? I have tried searching and all I could find was the midshaft thread from jet maniac. Any advice or experience is greatly appreciated. Mayday.
