....this might be a better motor for general use, if you're not looking for the
extra RPM's afforded with the tuned muffler. It's 5 bucks cheaper too.

Or fill the high performance mufflers exhaust outlet with metal filled epoxy and then redrill it to a smaller diameter than the stock diameter. If JB Weld will hold up to exhaust flange duty, which I have witnessed, without melting, it should do fine plugging up the stock exhaust outlet.
Me, I'd rather work it the other way around and provide the carb with the fuel it needs via crankcase pressure and an Iron Bay or Cline regulator.
