Not sure I completely agree with that .......but don't completely disagree either. :cool:
You've made your case; I'll make mine and then we can move on. Probably won't be able to "prove" it one way or the other with any scientific certainty. :roll:
Air box:
Is HUGE, compared to the carb throat. Can't see how that the box itself would offer any significant restriction. (And I think at one point you said you weren't sure that removal was worth the hassle).
Filter/air inlet:
Some restriction both these places. Some easy (and reversible) changes can be made here.
What I plan to do: (hopefully in the next week or so):
Borrow or buy a moto-tool so that I can remove the center of a stock filter (while leaving the mounting tabs for the diverter). This should remove a lot of restriction, with a much bigger hole and access to more of the filter element. I might then rotate the filter 90 degrees and put the diverter back on facing forward; will try it both ways.
This change can be reversed simply by getting a new stock filter.
Since it seems that nobody has done it (this way), I plan to drill 4 each 1/4 inch holes in the muffler back plate, INSIDE the ring. This change can be reversed by tapping the holes and screwing in 1/4 inch machine bolts (stainless, probably).
If these two changes achieve the desired result, I may then have a LOT MORE interest in your jetting project !!!! If not, nothing lost.
