I was thinking, of all the motorcycle engines out there that could be converted to AC use, the 1200 Bandit engine (also used in the early GSX-R-1100's) would be a great choice because of its large displacement combined with the fact that it's air/oil cooled (SACS), that gives it a great HP to weight ratio. It's also simpler to install since you don't have a radiator and glycol based coolant to deal with, just a large oil cooler. I found a company in France that is already doing this (http://vija-engines.wixsite.com/vija-en) but from what I can gather, their prices are higher than a Rotax 912 (close to $20K) which has the same power, so what is the point? Is there anyone out there who has seen this conversion done for less??
