    I was cleaning up the garage and found and extra elbow fitting like the one I used for my stator cover breather mod on my 2012 WR 300. If anyone is interested in the mod, let me know. I'll throw this thing in the mail for ya. Free!
    If youre not sure what the mod is Im sure I search will bring it up but I will post a pic today.

    Take off the stator cover, seal the hole(notch) at the bottom of the cover and drill a hole and install an elbow on top of the cover and run a hose up under the tank or into the airbox. Some epoxy an elbow. I bought a small brass elbow that was barbed on one end and threaded on the other end and tapped the hole I drilled in top of the cover.

    Interesting, I simply sealed the bottom hole with silicone and that's it, Do we need the breather tube ? For what ?

    Thanks.

    being sealed you will get dampness in there...condensation..from the heat cycles

    Interesting... wasn't thinking about condensation but make sense specially with lower temps... Another problem could be the Cable guide from the alternator letting humidity in ... I will have a look to put some breather hose in there...

    Do you have any pics from that hose barbs ?

    Regards.

    Scott Summers used to thread a small teflon tube in with the wiring. Seems the Honda 650s weeped a little oil when the cover was totally sealed. Creek crossings cooled the air inside and created a vacuum causing a mess. Ever look at your plastic gas jug on a cold morning? I've seen half full jugs almost creased in half from the contraction.

    I just went to a hydraulic supply house and got a 1/8" npt x 1/8" barbed elbow. Your local hardware store should have one. I'd take a pic but my bike is buried in the shed and I only have the use of one arm right now.
