Narley port CD with over 50 photos and drawings of high flow ports. “Full Auto”, “Axtell”, “Harley XR 750” and stock Norton ports included. A Street version is also included with suggestions for re-angled valves or stock size valves. AutoCad 2000 or later (or online drawing converter) required to view the drawings.


Send an additional $3 by paypal (and separate email ) to [email protected] and I’ll return a flash drive instead of a CD (more porting info).
