I think that engine would be a neat engine to collect, but would think twice about that engine being a possible motorcycle engine candidate unless you like it. For an 8hp engine weighing close to 150 lbs in a motorcycle, I would lean more towards the Yanmar/Changfa type 4-10hp versions (around 100 lbs with internal charging system). I don’t know what type of motorcycle you are thinking of building as I’m building a Bio-Diesel motorcycle also. I just bought this fine piece of Russian equipment with the Hatz 2g40 engine. Please note the fine use of chain link fencing material as an exhaust system. See:

http://www.peace65.freeserve.co.uk/Pictures/diesel.htmhttp://journeytoforever.org/biodiesel_bikes.htmlI also have a Briggs/Daihatsu turbocharged engine waiting for a home in a motorcycle/something, also have two of these. See:

As for a drive, I would stick with a CVT type belt torque converter as a manual transmission in a Motorcycle with a Diesel engine leaves a lot to be desired.
