it's used by few companies, maybe many but that's irrelevant, main point it's a Japanese clone of the honda nx250. knowing that we can realize there are big bore kits available for it, which is huge and why I pointed this particular engine out.. 25hp stock, who knows what a big bore would give.

but i was hoping zorge would chime in with some hard facts..

fwiw anything without fins is a pretty safe bet to be water cooled
