jetting help

[400exnVa]

need some ideas on what size jets to run. here's my mods, alumium airbox no lid, k&n with outerwear,and stock exhaust

[yellow_ho_01]

first off get yourself a better aifilter, use something like a white bros foam, then get yourself ATLEAST an E-series slip on pipe, THEN after you do that get a K&N / DYNO jet kit and go from there. Jetting your quad with what you got done wont make enough of a difference, if any.
