    Sounds like the crankcase breather.
    2002 KTM 400 EXC, this bike is awsome!

    Quads I use to own:
    FDO 463ex, Gas Gas 300, Gas Gas 450, Rancher, Yamaha Warrior, ATC Big Red.

    If you can't afford to fix it or replace it, don't ask to ride it!

    yes its a crankcase breather, it releases the pressure from the crankcase and sends the air pressure into the air intake boot and boosts the intake of air.
