Where do all these port timing numbers come from? What about the angle of the transfers, polished ports vs textured, or intake resonance, indexed sparkplugs or otherwise just grinding away at the piston? Or the countless other ways to set up swirling motions in the intake, base and chamber?
It seems amongst the builders there is a great range of approaches ranging from; using guarded secret numbers and formulas handed down for generations, to quantum physics and super computers running real time 3d graphical simulations, to a "get to know your saw" then do what feels right, yet for other builders its more a story of a wonderful journey to find ones self, having relativly little to do with saw building.
So what do we really need to build saws, inner piece and enlightenment, supercomputers and an encyclopedia of formulas, or just the inside track on the magic numbers. Or is it just a lot of wrecked saws and a bit of this :bang: ?
Lots of people have posted the success stories of their porting work, but what about the rest of the cases, broken rings, jammed pistons, busted rods....
