most of us dont run those mini filter plugs used back in the day.......
they were once quite popular on the older two strokes....and we would oil them up as well to help stop some of the dirt from entering the air box....but usually 'most' of us would use about twenty of them dang things.....it never seemed like six were enough.....
so...with that being said...I dont believe your gonna quite get the flow your looking for with just six.... hence the reason why most choose to either just remove the lid....or use some type of air box eliminator kit.....
so any jetting recommendations would just be guessing on my part....
however.....plan on anything between 130 and 160.....
or...add another dozen or so of those mini-filters and go with 162 main and maybe 45 slow jet.... but if it were me...and I wanted to eliminate the guess work.... just buy an HRC jet kit.... remove the lid for NOW..... and have fun... then mod your lid as you see fit but adding as many of those filters as you need until she runs correctly (not rich) after installing the HRC kit....
plus...the HRC kit will give you a nice adjustable needle as well...... .and no, the 06/newer machines do not come with adjustable needles....
if going this route....dont use a #45 slow jet (pilot)...the NGPR needle will be sufficient for increasing the fuel at low/mid rpms....
