lid box off

[y-man]

hey guys im thinking about taking the lid off and i have a moose racing foam filter in my ltz and just cleaned it and was wondering how far i should turn my fuel/mixture screw to make it run right it runs lean with it off and which way to turn it and if my flilter would do good with the lid off thanks guys

You should never have to adjust the fuel screw with the exception of riding in some elevation variance. With the lid off you need to go up in mainjet size.

dont be surprised if ya have to bump up the PJ to a 25 this happens when the fuel screw needs to be out more than 3 1/2 turns
