Thankfully my fairing caught the exhaust resulting in little damage and a functional machine so no major problems there. Now back home and post some discussion with Andy Green; I had decided to make new mounts that should survive a little better than what I had.

The solution proposed to me was to use tubular engine mount bushings in some steel tube that would be welded to my frame. The exhaust would then marry up to these bushes via some split box section . The box section would be welded to the pipe via a stress spreading sheet that would be we...
