i was runnin 310's and 27.5 pilots and i think the needle is on the 4th clip but could be the 3rd (cant remember at the moment) when i had my t6's on and that was perfect air screws 1.5 turns out also. also no airbox lid and delta 2 reeds, and even switchin to my rockets its still spot on
340's sound really rich....but if u say its workin out for ya then
