what jets should i buy

[05strokinfx4]

i just bought a 08 400ex red/black, and have recently bought a uni filter and the lexx slip on ( cause it is cheap and has good reviews on rockey mountain atv) and it looks pretty nice havnt got the mufffler yet but have the uni on. I was wonting to know if i order a 152 and a 155 main and the 42 pilot will i be good to go,and is the 155 good enough for a outerwares air box lid when i buy one r should i get a 158

Save your money on the pilot, stock is perfectly fine. Just turn the mix screw to 3.25 - 3.5 turns out. For the main you got the right idea 152-155. When you get the outerwear lid bump that main again.

so go to a 158 for the lid
