Re: How do you port and polish
So I decided to port and gasket match my intake and exhaust. I was a non believer before, but now i'm sold. The intake was pretty close already, but the exhaust was about 20% blocked. I matched the pipe as best I could and took it out for a test ride. First, this thing runs smoother. Second, it accelerates MUCH faster now to top speed. Top speed is the same, but the time to get there is reduced. Not too shabby.
