qboronyrican Posted October 23, 2009 Report Posted October 23, 2009 how much of a difference is there between running a open airbox w/a k&n filter and running k&n pods w/ no air box and also foam pods w/ no air box? what performance gains are there? what type of jetting size changes would there be?

Burt Reynolds Posted October 23, 2009 Report Posted October 23, 2009 There wasnt much difference between the two in performance on my 4mil. I had a 4mil with 33mm carbs,and cpi pipes.Im sure theres a difference but none that i could tell by riding in a field. I switched from uni-pod filters to an airbox with no lid (had a couple holes drilled in the bottom) When i replaced the pods with the box i had to go from a 160 to a 155 main,stayed with a 42 pilot,just turned the air screw out 1/2 turn.
