I have a guy that swears MOTH BALLS realy BOOST the power. just add 2-3 per gallon. BUT the engine don't hold up well after. OOPS.

This is crank horsepower, of course. 36 or 38 RW horsepower seems reasonable for 42 crank HP. The service manual says 35.3 kW, which is 47.3 HP. I'm not sure how they got that, but ALL manufacturers inflate their HP numbers. Probably run it in a pressure chamber or something.
If this was a three cylinder two-stroke http://www.motorcyclespecs.co.za/model/kawasaki/kawasaki_h2.htm , I would expect almost twice that, but a four cycle single is at a huge disadvantage.
