no details on the mounting yet. this is what I got from a guy in europe who I ran into online. he's done two C10s in the past. however, he had no pics showing specific mount points.
my plan is to fabricate a plate which would use the upper and lower engine mounts on each side, then have some type of downtube from that plate. that would attach to square tube along the bottom of the bike and attach somewhere around the center stand in the back. that square tube parallel to the ground will allow me two mounts at the bottom for the base of the car. the upper in the front will attach to the plate. the upper in the rear will likely have to attach somewhere under the bodywork. I've seen a nice example that went through the bodywork.
this doesn't show the best, but might give you an idea. however, my install may be more crude in that I am thinking of running without the lower fairing parts.
