from the looks of that filter setup i would try leanin it out alittle maybe a 150 main... with 4in long pods i run 150 summer, 160 winter... at a race as it was gettin colder i put on a 6in long filter and it got hot and seize on me (cant remember if i had 150 or 155 n at the time)... when it cooled off i put the 4in back on and ran the main (more laps) and it never got hot, so i know im right on with the jettin
