Topic: Paper filter to foam filter (jetting)

[gregripko]

I have a uni foam airbox filter and was wondering if the slow jets have to be changed from stock size? Timing good, sync'd clean carbs, can pull 90 WOT but want to make it easier on the wrist by potentially a fine tune. Hoping this might do it.

Slow jets seem much more tolerant of changes to intake or exhaust.  I doubt paper to foam will change much at all.
