    There is a vent tube...which has nothing to do with the crankcase breather system. I also had sent an email to a bloke in the UK that he and his wife ride these..still awaiting a response.

    The tube that comes off the breather also has a much larger ID than the little one off the oil tank itself...very confusing for sure.


    Based on the fiches depiction and what i have in hand..i would say it is the OEM pipe ..right down to the very same spring around it.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      the early TX had a reed valve type affair on the airbox which the breather pipe was connected to.

      scroll down to picture #5 it tells you there

        I have added that to my FAVS for reference later. So it would seem I need a nipple and some modification to my airbox ( which has no such modification as pictured ) and revent the tube back to the airbox.


        May add an inline filter as well to grab any globs of oil in the pipe. You sir may have solved the quandry!!!

          it would be very easy to fab up a small nipple as you call it to fit the pipe onto, or simply just drill a hole in the airbox and silicone the pipe in there

            I gota refit the airbox into the frame once we get the engine back in and do some measuring..but you have set the path for sure.
