Well we took the motor apart.
Pistons came out, new rings, new bearings, new guides, and new seals.

We honed it by hand with a powerdrill and the honing beads and kerosene.
This was done in a machine shop.
Thats about as much as I had a hand in.

The shop guys did the rest, they put the bearings, rings, and pistons.. and the put the entire motor together.

The rings.. I don't know what they are, the machinist chose them.
He said he bought better than stock rings. But they're not something mega-expensive. Just a little bit above OEM standards.
