So can anyone tell me if there would be any benefit of just matching my exhaust port to my pipe. I just rebuilt the lower end this summer but didnt do any porting on the case (and dont feel like splitting the case again anytime soon). Its a stock cylinder and head with high flow 14mm bing and intake that match the cylinder intake port. The exhaust is a techno boss, so much larger diameter than the exhaust port.
I have a dremel but just want to know if it will make a difference. What is the suggested dremel bit to use for this kind of work?
