[QUOTE="morph, post: 257983, member: 26977"] hey privymaster when you say ported do you mean the ports were cleaned up to flow better or have all the ports been resized with widths and heights changed.i was just curious as i have an 86 500 with a CT RACING full drag port job and the ports on it dont resemble the stock layout .this thing cranks. at the moment i'm upgrading the head/inlet/pipe to match it and so far 70hp at the rear wheel is looking attainable porting alone has givin me 56hp from the stock 40.
