Found in an old magazine,  it's carried out on different engine but clearly shows what happens when removing the std airbox and then to compensate via rejetting to run correctly.

Clearly shows with test data why it is difficult to sort out just by changing existing jets when it's really a response curve mismatch that is the root cause.

And the second page to conclude.

Last two paragraph really do summarise what's needed to get out of situation created by using very different induction to std.

The manufacturer follows exactly this process in their research and testing to get it right,  which is negated when altered.

Looks like it would be a good read if it wasnt sideways.. You cant even click on the pic and bring it around the right way...

Apologies as not scanning but using camera to capture,  trying to keep resolution enough to still read text ok on here with file size allowable.


I'll try to get something else up to correct it,  waiting for sun to rise and give enough light  :)

Hopefully that's more useful.

Why I found it interesting is that it gives a formal illustrated view of the problem existing when asking the question of what jets to use in modified systems.

Clearly demonstrated is the classic increase in main jet size to cover one area,  which results in running rich in another.  At some point you get a flat spot or too weak a mixture which cannot be logically solved just by jet sizing alone.
