Porting the header/manifold?
I was looking at the opening on my header and comparing it to the exhaust port of my engine, and there is a huge difference in size. To me that would be very restrictive, but maybe you need it to be since it is a 2 stroke engine.
Has anyone ever tried to enlarge the exhaust port opening on a side exhaust header/manifold? Would there be any gains in doing this or would it be just a waste of time?
I used to care, now I take a pill for that.
