Would it be in any builders best interest to find out
why an AM jug, ported the same as OEM -- doesn't show the same performance? Is it something simple but overlooked? Is it something difficult, and not overcomable?
That's what I see coming from a lot of builders, and not just ones from here.
It boils down to construction, observation, adaptation, better end-product.
Oh, and I'll muddy the water even more. . . My personal observations show that longer port durations help at elevations greater than 0-1,000 feet above sea level. More air/fuel perhaps in a given rotation, needed in an atmosphere with less oxygen? Perhaps.

I see a lot of you sea level fellas blanket statement on saw numbers, and y'all are usually under 1,000 feet.
Muddy, muddy, stir, stir. :msp_biggrin:
