Specification:
NEW Reproduction style air cleaner & clamp to fit the Honda Z50 1972'-1978' and Honda QA50 1970'-1975' and some XR50 & CRF50s
Measures 2-5/8" long 2-1/2" at widest part and black rubber opening size of 1-1/16" Last 2- pictures show a couple types of carburetors (not included) that these will fit. I also added some pictures of this installed on a QA50 ( the bottom of the air cleaner will seat on the carb until it hits the motor & the clamp screw should be on the petcock side of the carb not to interfer with the choke lever) These will not fit the early 1968'-1971' Z50s stock carburetor.
