Good point, especially on the jetting. What I learned while working with Q16 was that most carbs couldn't handle Q16 with just a jet change. I eventually ended up with a custom 1250 carb from BLP that could switch back and forth from gas to Q16 for dyno testing. On that carb we changed metering blocks rather than jets since the internal fuel passages all had to be larger to work with the larger jets. That was a nice dyno carb, it would've been perfect for this 572.
