HEY everyone. I'm just doing my end of the year maintenance on my kfx 700 and i was wondering what i need to do for the 12 hole mod.I know you drill 12 holes in the intake box but how big? is there a certain place i should drill the holes? what other simple things can i do for next spring? I already have dual big guns exhaust, jetted, k&n air filter, Epi clutch, and the dyna tech rev box.
