So according to ebay my piston arrives in a few days. I took out my case bearings and seals to go and buy new ones and cleaned everything up in the bottom end. When i got to the cylinder to repair the exhaust stud threads i noticed a little gouge above the transfer port. You can roughly feel it with your nail.
Now putting new rings into this cylinder i feel like it would wear really fast. The piston was in a really bad state but it still had good enough compression. Do i just install the new piston and run it like this or do i take it to a machine shop to just hone it a little bit or can i hit it with some sandpaper? I would buy a new cylinder but i cant find one for the YD100 and the LD100 rebuild kits are almost as much as an entire complete engine.
