Got the back rest installed, not to bad. My first attempt with the bread knife I had too much angle and got close to the back rest portion of the seat. Corrected my angle and all is good. Now I'm just waiting for the luggage rack and spoiler to get here and try my luck again. I put some highway pegs on that a friend had given me but my legs rub the fairing. Kind of puts you in that "giving birth" position. Back to the drawing board on those.
