That was my thoughts, but now I see he is making a custom frame. That makes sense. I can't imagine it is much diffrent than a wheelie or climbing a hill.

Good luck with the project.

Arigato:
I've seen a few CR500 conversions that do the same thing.  However, the Service Honda version uses their own billet wishbone(that clears the exhaust) that they weld into place. This allows them to mount the engine at the angle it would normally be.

Hangtime,
  It won't effect performance but it could effect the handling a touch.  The location of the crank centerline (rotational mass of enertia) has an effect on how much weight gets put on the front wheel in cornering.  Over the years of development of dirtbikes they have been playing with engine position moving it a few mm here and there.  Even the CRF450 has had small engine position changes (I recall) from inception to the latest model.  That being said, I would go ahead a do what you need to make it fit, you likely will not notice anything (other that riding the coolest aluminum framed KX500 around). There is a book (a can't Recall the name - something about chassis design) around for a few years that talks about chassis design and handling of motorcycles.  maybe someone has a copy that can post it as a .pdf. good luck. Cam.

If I rotate the engine CC would this deliver more inertia/weight transfer to the front end? If so that would be good for me as I am 6'4" and tend to sit further back on the seat. I like the idea of milling a reed spacer to help align the carb to the boot, thanks Alan.

Yes, it would.  On the Service Honda bikes, they rotate the engine just a little even with the custom wishbone piece.  They are noticeably more front heavy than a steel frame CR.
