love to know how to port 2 srtokes, the theory. I have done 4T stuff in the past to stage 3. That is dead easy as there are no timings to worry about. Just flowing and valves.

this is a head i done last year for a VW




I can see in my DTR`s head, that is ruff , just in the transfer ports, i was thinking of gettin the dremmel out and cleaning it up..
