Bought a modded '98 with a wiesco 780 big bore kit that has the PTO side piston sheld out. After talking to some folks about the set up I'm looking for a good low mile engine that I can put my reeds, pipes, clutching, etc on to. I've been told the wiesco pistons have a great deal of silicone in them causing a big difference in expansion and contraction compared to the cylinder itself. So let me know what you have and if anyone is interested in this engine as a whole or for parts let me know.
