hey guys. i was curious if i could take the large lid for my airbox off and only use the smalle one. i have a KN filter with outerwear and i ride in minimal water. i already have the snorkle extension removed. i m just lookin for a little boost and my water riding is minimal

anyway, i could use some help with jetting too

im sure there is some of you that have some mods similiar, i mjust curious what you guys are running because i cant get mine rigiht for anyhthing..

 

Thats the way I ride my stock engine 400 Trailblazer with a 42mm flatslide carb and 390 main jet.
you might have to rejet. Any performance work on engine and we run open K&N air filter without the box.
