Thanks for the reply. Great to hear someone else is thinking about using one of these! We need to swap thoughts on design ideas.
From what I've seen the bottoms of these engine look like they would mount up pretty easily to a flat plate..all that would need be done is drill some holes in the appropriate places and mount the plate to the bike.
I'm almost sure at this point that this is the way I'm going to go unless someone pipes in with some seriously negative info on these motors.
Thanks again for the reply!
