Off hand, I really don’t… I’m afraid I’m not an engineer or mechanic, just read to many car and bike mags. However I did a quick Google for some info and came up with a couple of interesting links. Hope it’s ok to post these Jimmy…
http://thekneeslider.com/motorcycle-powered-cars/ Seems to be a list of sources for info on bike engines in cars.

Some one trying to put a ZX-9R engine in a 126
http://www.zcars.org.uk/mini/conversion.htm Zcars have a video of their parts used in a mini bike engine conversation.
Looks like the info is out there, just a question of knowing the right questions to ask, which I think you’ll have more luck with then me.
Cheers,
Mat
