    Hello, my exhaust is dripping a lot at the front. Opened it up and the o-ring completely disintegrated. Does someone know a measurement of that one? I can't really measure mine. Seems like 1.8 or 2mm thickness. Bike is a WR250 2002 but that o-ring is on every exhaust from 1996 to 2013 and 125,250,300...


    Best regards Lars

    Took some non-scientific measurements today :)

    Just realized these measurements are from the o-rings where the pipe attaches to the head...sorry.
