Unfortunately it doesn't work that way in the real world.
For one thing, even if the heads of mass produced bikes had all their threads in exactly the same sync (which they don't) the spark plugs would still not be. The ones I'm holding in my hand aren't, and they weren't exactly cheap, so, so much for theory #1......JC

I think there are many more variables that you can control (fuel quality, a/f ratio control, vehicle weight etc.) that will do more than attempting to position the spark plugs in the same position. Besides, there are alot of plugs these days that have 1 center electrode and 4 side electrodes making its position almost negligible.

As for theory #2, whether or not the fuel/air mix swirls perfectly, depends on many variables, including variables caused by after-market mods like air filters, so, so much for theory #2.
The question isn't whether or not the bike will run, it's, can you make it run better?

Agreed...but the mods will make more of a difference than spark plug electrode position.
