Thanks for the post, GB. To be honest, I wanted to do that, but I was afraid I'd be afoul of a "RULZ" if I did.

Sleeves and gaskets for the first 4 engines are here, order for the pistons is in this week. First 3 engines will be for testing, then I believe Bill's plan is to intially have 24 conversions available.

To answer one question I've seen, this big bore kit requires no mods to the cases. Your cylinder sent in, sleeved by Bill, then you get it back with the rest of the stuff, to do in your garage. We should be able to have jetting recommendations available, since there will be 3 test bikes.
