HONDA SAYS THIS IS FOR THE 86 CT110, BUT FROM WHAT I CAN TELL IT WILL FIT CT90'S 78 AND 79 AND ALL CT110'S. IT IS A LITTLE BIT DIFFERENT BUT CHEEPER THAN THE ALTERNITIVE.IT EVEN COMES WITH A NEW O-RING AND BOTH SCREWS. THIS WILL ALSO WORK FOR ATC70'S TRX70'S, ATC110'S AND CT70'S 78 AND NEWER. @ *PETCOCK_ASSY CT110_OTHERS 16951-459-920 1/22M (36K) 36k @ *SCREW 3_X_12_MM (SOME_PETCOCKS) (SOME_SWITCHES) (SOLD_EACH) 93500-03012-0A 1/22A (B156E) B156E @ 18MM ROUND FUEL FILTER SCREEN ATC70_ATC110 C70_CT110 OTHERS (SOLD_EACH) (275M)FITS: ATC70 1978 TO 1985 ATC110 1979 TO 1983 C70 PASSPORT 1980 AND 1981 ONLY CT110 1980 AND 1981 ONLY 275M
