T-4 Airbox

[Ryan300exRider]

Hey guys i just bought my 400ex and at the shop they are putting on the t-4 slip on and jetting it now when i get my 400 if i take the airbox lid off do you think i can still run it with changing the jets.....Will it hurt the quad???

Bump I have this question too....

it will run but it will hurt the performance of your 400 because you'll be getting more air but the same amount of gas, causing you to run lean and if lean enough will cause damage

just up the main jet one or two jet sizes and you should be all set
