just took the RAW 80cc out of the box. mounts fit 1-1/4" frame , but my micargi mustang has 1-1/2" frame tubes. has anyone got any ideas on mounting? the enigine stud holes are 1-5/8"apart on-center so there's not much room for grinding out and widening the frame saddle of the mounting block to saddle the frame. and as for the front mount, I have seen many "far away" shots of bikes, but no up-close shots. are guys welding short tubes vertically off the bottom frame tube for the front mount to saddle to?
