I mean that's an 80cc kit. Rinse out the bottom end with some gas to clean all metal crap out. Buy a top end kit 33$ and it will run again. It's not hard. If you need to see how to fix basic stuff I have a how to video. Bible of motorized bicycle repair. Covers a blown up trashed engine to back to looking factory new when the videos over. These are hobby type engines. They are not by any means reliable transportation Video: https://youtu.be/7S_dkB7lZDY?is=s0GrOVEyY6Ugcp1P Edit: whole top end https://a.co/d/00cGTmdQ
The parts are cheap and plentiful, just replace the cylinder and piston. While you're at it, replace your exhaust bolts with studs, washers, and nuts and port your cylinder. Good luck and safe travels my friend. Here's a link: https://a.co/d/89mJBSJ
