Biggest problem with those cart motors is that the sprocket is mounted on the wrong side of the engine for a KR. Of course you could probably monkey around with the rear end of the bike to make it suit if you really wanted to.
Would certainly make an old KR get up and boogie though.

I think you will find a Rotax 256 was used in many many motorcycles dating back to Armstrong's in the very early 80's, then through to the first Aprilia GP 250's until 1990 or so when the first Jan Witteveen(genreflect) designed V twin came out. The V twin still used the same cylinders

Quick update have located a copy of the JJ Cobas frame, tank and fairing moulds. From the engine number a contact in the US told me the history of the engine has a motorcycle gearbox(instead of kart) all looks good inside. Best thing is new parts are easily available and cheap, $75USD for a piston,ring, gudgeon and clips!

Have the engine at a friends place in the US ATM, have sourced a frame close to you so expect a call when I come to organise freight, got a set of RS 250 forks, just wheels and triple clamps to go.
There are 2 Armstrongs here both punch out 70HP weigh 90 odd kgs
This has PV's hopefully Aprilia RS 125 RAVE valves fit it which should see us around 75HP with a fat bottom end. Gearbox ratio's are so close, top 3 gears rpm drop is about 500-600rpm.
