you have to jet up a bunch. removing the airbox lid is a big mod for a blaster. lets it get lots of air. drilling some holes like you did in the lid helps, but is pointless b/c it doesn't let it reach it's full potential and you can still get dirt and water in the box. just rejet and take it off or get an outerwears filter cover for the top like this one

although it doesn't make it completely water proof, the lid mod does help to keep excess dirt and water out of the box but still lets all the air in.

i am running a 270 main jet right now, how much higher do you think i should go something like a 290 or 320 range
thanks for the help guys i am a first time quad owner and have never really messed with jetting much so i wasnt sure how high to go
are you sure you have to re jet when you take off the lid??? because that was like the first thing i did and i didnt notice any power lose or anything
