1989 Honda CR500 Engine

1989 cr500 engine. Engine was in running condition when pulled from the bike. Was going to put it in a go kart, but never got around to it. Stock bore 89mm. Comes with new proX 89mm piston(not installed) Engine has full transmission. And I have the kickstart mechanism that will need to be installed as well. The threads on the flywheel side of the crankshaft will need to be chased in order to get the nut on. Comes with cdi box and carburetor. I do not have a coil for it. $3,500 obo
