There is a company developing a very slick use for this engine adaptable to any 2 or three wheeled bike that should be available in the near future.
Alcohol is a good fuel for that 2 stroke. There is a good chapter on that in David Blumes book. But those Chinese 2 stroke kits are sketchy at best. There is a Russian version of it also but hard to find and harder to find parts for. Tanaka makes a really nice 2 stroke and so does Mitsubishi but are generally used for rear mount application via chain, belt or friction.
i picked up the honda gx50 4 stroke i love it. i found the 2 stroke to be a very dirty motor
good if you have a garage but if your living in a apartment you need to put a bag over the pipe if you have carpet. drips black oil everywhere. well that and the oil gets all over the rear of the bike and on your shoes when running.
the gx50 has a cast iron sleeve.
