I have a completely stock 01 warrior. I bought a new K&N air filter because the old original one no longer fit real well in the cradle of the air box. Like it dry rotted or something, anyhow, do you need to change the jetting if the only mod at this time is the air filter? wondering if i can make the mixture screw adjustments and get by.

 

no jetting changes needed, nor air fuel mixture screw adjustments... should be just fine.

 

thanks for the info
