    TW main jets are numbered 288-14343-xx-00







    Some TW main jet numbers are superceded by 288-14355-xx-00 numbers



    Some 288-14343-xx-00 numbers are superceded by or supercede 288-14329-xx-00 numbers





    I think we just may have more choices in main jets than one can shake a stick at. Look closely and you can find the #126 and #132.5 main jets that have caused confusion are from the 14355 main jet family, not the 14343 main jet family. Both have worked well for people with the late carbs. Note that the #128 from the 14343 family has been superceded by the #128 from the 14355 family (3rd picture).

    It would also be interesting to verify some of the Mikuni stuff as well. With a set of numbered orifice drills as a gauge you could probably determine whether or not those 112.5's were in fact the same as 112's for example.



    I can explain it to you, but I can't understand it for you.

    Powdercoated '87 frame, extended swingarm, YZ fork legs, ATV tire, 14/55, XT350 tank, spliced quick-release seat, disc brake conversion, beeg headlight, beeger rack, Lizrdcooler, Lizrdventz and bunch of other stuff all covered in invisible ink.
