    350X carb install on a 250SX

    Anyone know what size jets to use in the 350X carb ? It will be installed on a 250SX motor.
    I will be installing a FMF powercore 4 complete exhaust.

    Stock is 130 if you remove the airbox lid I would start with a 140 and see where the gets you. Maybe buy a few and experiment. On my BR w/ full cobra and holes drilled in the airbox lid a 135 was right on.
