Hi All

When 2 strokes are ported, are the actual port sizes increased, or do they actually do more of a "port match" to the intake and exhaust manifolds?

I've got my engine broken apart and if I dry fit the parts, there seems to be a lot of room to enlarge the ports so that they match the exhaust port. Is it worth digging in with a grinder?

I've ported a couple of 4 stroke engines but never a 2 stroke.

If there's a guide out there somewhere that would help also
