it will work and a little bigger manifold would be good not a velocity stack, those are for two strokes
Why is that? I have the 22mm mikuni copy from PCC, as well as a real 20mm mikuni off of a ktm 50. They have both performed as expected, without any problems to speak of. I can understand wanting a certain kind of choke, but paying twice the price just for that is kinda silly if you ask me...as long as you understand it wont be as good
