I have a kioritz that has a forward facing plug, measured the bore and stroke and it seems to be a 25

does it have a clutch drive and a fan (not a flywheel) mounted on the side the plug faces? if it's like that, it's exactly the same as the one I got, I don't know it's power yet as the scooter I made around it has a couple chain alignment issues... (was using a crappy welder, now have a better one)
