A few years ago I bought a pilot conversion motor for $700 on Ebay. The sleeve was broken.

I was not liking my green bike's 350 Power valve like I used to since running the 431 Puma. I sent this motor to Pete at Hybrid Entertainment to rework a Pilot cylinder I bought on ebay. It was ported for duning and bored for an 83mm piston. The 4 mil crank will give me 411cc.
It is bore-able the 85mm or 431cc. He sent the cylinder and bottom end back to me. After redoing the bottom end with filler in the case and a case bore for the pilot skirt, it was ready for paint and polish.
