Most regulars on here are far more experienced than I, but before you take to the head with a belt sander I think you should do some research. I know these 2 strokes have forgiving tolerances but still need to be treated with some integrity.
Maybe you can look up go-cart sites for hotting up the donk, they were popular for that some time ago. Have stumbled across some sites with some impressive rebuilds.
But please read some other threads on here and other sites on doing it up or you will be wasting your time and resources.
No offense is intended. Wish you luck.
