    Bike is used, and i don't know its history. Breather hose comes off motor and is open to atmosphere behind the motor. Is this correct? I can't find any info on parts fiches or manuals i have. Buddy says it should go to airbox, but i don't see anywhere for it to go.
    Thx for any info you can send my way.

    Should be connected to a spigot on the carb at the air box boot. Most will plug that spigot and install a small vent filter to the hose and route it up high away from potential water ingress. Hope this helps!

    thx. Yeah,that's not there. Think that part of the carb has been replaced with one of those power now widgets. Guess easiest thing is to get a little filter
