Anyone know where to get kawasaki piston and rings for invader 440? My engine fried a piston after fresh rebuild with cheap pistons. Jim had sent me a NOS piston and rings several years ago and i was gonna use the other new cheap piston that did not fry. But after inspection seems like the skirt was distorting on one edge and going to damage cylinder. I would rather put in one of the used factory piston and ring than to put the cheap one back in
