Good To Know

Q: What symptoms point to a bad carb mounting flange? A: A surging or hanging idle, lean popping, and an idle that changes when carb cleaner is sprayed near the flange are typical. These point to an intake air leak at the boot.

Q: Does this flange fit both model years listed? A: It is cross-referenced to OEM number 0115-544, which covers the 1976 and 1977 Z 250 fitment shown. Verify against the part on your machine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
