Honestly, tear that one down and rebuild it, buy a new piston and cylinder and you can do some modifications while you are at it. It would be cheaper than buying a brand new engine off eBay or Amazon which is about roughly $150. You could probably spend $50 or so to rebuild the one you have. Test for spark, fuel delivery, and compression. Those old piston Port Motors are really good Motors

As long as the transmission is still good those use the box roller chain transmission which is very very hard to come by...

I have one I took off. Trans and motor. Don’t know anything about it. Tore down and rebuilding. Added reinforcements to frame and added Tillottson racing engine. 212. If you need it let me know. I need a 35 chain rear wheel sprocket. Anyone know where I can get one for a APC mini Harley chopper
