Ok, what a delemma. Going through the same deal. Got mine, 2 plastic sliders, 2-12mm X 100mm (4") X 1.25 thread pitch Bolts, 2 flat washers, and a spacer. The instructions have 2 pictures 1 of each side of the bike. It starts with telling you to start with the left side but the picture is of the right. Then the other with the picture misslabled again. The slider with the stepdown goes on the right it fits in between the bodywork, it requires the spacer that wedges in the frame, not happy with the fit. However bolt goes in well with lots of depth, Loctight (red) and 41ft/lbs of torque. The one sized slider goes on the left, no washer or anything between the frame and itself. Now TO MY PROBLEM !!!. The bolt is not of adequit length, 3 to 4 threads in and its tight, 1 turn of the wrench and i have 4 less threads OUCH. Pull out slider and inspect motormount, not to bad. lots of thread length left Re-install orignal bolt and try to find longer bolt. The threaded boss (motormount) is app. 1" long with 1/2" space behind. So I will jst go downtown and pick up said bolt 1" longer. WRONG. 12mm X 125mm X 1.25 thread pitch Cap Socket Head not so easy to find. The one place (searched about 7) that could get it said I had to buy 5 at 5$ ea plus shipping, Pass. Ok called motovation monday, talked with Roland gave him the lowdown he said he would find me a bolt. Later that day recived e-mail, 120mm (4 3/4) bolt on its way. Waiting on that, Should work, Will let ya know.Banzai.
