What sort of power where you getting from the MC16 in race trim? I'm toying with the idea of racing mine, some of the TZR's are bloody quick though, I've got a set of JHA pipes, MC18 carbs, MC21 sp cylinders, and going to run RM125 single ring pistons, so hopefully enough to keep up with the yam's and aprilia 250's that go well too.
How did the handling and brakes compare too? I know it's 20 odd years ago so probably hard to say for sure :p
