I have a 1990 NS50F that I built to a 63cc with a Wiseco KX60 big bore piston. I run a 28mm Keihin PWK carb with a Moto Tassarni V-Force reed block & a Boyesen X wing. The flywheel has been lightened 4 oz. & I use a Posh Super Battle CDI. Currently I run a gutted stock pipe I built close to KX60 pipe dimensions. It seems to run fine with that pipe, but if I can find the best pipe for a big bore NSR50 I think it should work on a NS50F. Any thoughts?

Okay, so reading on old posts here, sounds like the jolly moto pipe is the pipe I want, anybody here had one & know if it's a mid to top pipe or a bottom to mid pipe? And does anyone know where to get one?
