  • 1993 Yamaha 250 txrr / Weird Carb. Question

    Can anyone confirm if the #4 carb. is supposed to be different than the other 5 carbs?

    Motor is not reaching max rpm.

    It is mostly identical except that it is missing a jet that comes in through the side, horizontally on the air box side. Jet is not actually missing. carb does not even have the hole for it.

    Also, this carb is the one with the idle screw.

    Cylinder 4 is also the lowest compression on the motor (still with in spec.)

    Stbd eng. all carbs match.
