Just a small step and I have yet to get it in the post, but I have secured a 675 cam for the Rotax, not the hairiest cam in the world, but it is the one that Mark Forsyth ran on his single all those years ago - and I have the rest of the engine spec for his bike of the time - including exhaust lenghts as set up on the LEDAR dyno. So not saying it will be anything as good - but I do have a 'parts' catalogue to follow, which seems to be a start.
So I guess I need to get the frame welded so I can take the engine apart...
Maybe I will get an evening pass soon
