Has anyone installed the Rizoma grips ? I just received the grips (natural/silver), matching bar ends with sliders, and MV adapter for the throttle/grip from PJ's Parts - I want to install them for my Christmas present to myself. If you have done this, is the throttle grip installation fairly easy or am I going to mess it up - I am mechanically oriented but I do not want to mess up the throttle cables on an MV as my dealer is a ways from my house (about 60 miles). Any advice ? It looks easy ???? Famous last words.
