    by brucelee » Sun Sep 14, 2008 5:22 pm

    Hello I have a05 crf 450r about 10 hrs on complete rebuild, athena big bore, crank valves.All of a sudden I started blowing trans fluid out of the trans vent tube. I pulled clutch side off does not look like any of the crank seals failed? Any one experiance this before or have any suggestions. thanks Bruce

    Hey Bruce, welcome to the site!! Love your movies BTW...

    Crankcase breather hose is blocked, pinched, etc.

    The pinkish clear hose going down by the back of the carb has a black plastic cap on it. Remove the cap and drain it for starters.
