Todd and I talked about stroking the engine and I suggested doing it like we do with a Harley: New crankshaft, piston and cylinder. This allows you to use the same crankcase and connecting rod as the "short stroke" engine and it also makes it easy to update in the field. The crankshaft is one piece (the pin is not removable) so you need to replace the entire thing. I think this engine would respond well to a stroker kit - just like an old Harley does.
