– Chrome
– Vented
– 2.5″ diameter
– Fits right side gas tanks on H-D 1973-1982 Big Twins.
– Replaces Harley # 61102-73a

These bayonet style gas caps (also known as cam gas caps) are vented and are chromed steel. This is a 2.5″ diameter gas cap, larger than the 1972 and earlier 2″ diameter gas caps.

This vented cap works with the right side gas tank on H-D Big Twins 1973-1982. For more information read the differences for various year range motorcycles below. This gas cap replaces Harley-Davidson OEM # 61102-73a.

Here is a breakdown of the year ranges of Harley-Davidson motorcycles that accept bayonet style caps, the differences in the gas tanks / gas caps, and the Harley OEM numbers for each. This should help determine which gas cap(s) you need for your motorcycle.

1936-1964
Bayonet style gas cap both left and right, and both gas caps are vented. Both caps are same ‘depth’ in that they engage the cam bung on the gas tank in an identical fashion. Caps are approximately 2″ diameter. OEM part number

61103-36

1965-1972
Bikes in this year range that take a single gas cap use OEM

61103-36

. Bayonet style gas cap both left and right. The left side cap is non-vented and the underside is ‘taller’ than the right side, vented cap. This is because the cam bungs on the gas tanks are different left to right side, and gas caps are not interchangeable. Caps are approximately 2″ diameter. OEM #s

61103-65

for the left, unvented and 61103-36 for the vented right (Same as earlier year range)

1973-1982
Bikes in this year range that take a single gas cap use OEM

61102-73a

. Bayonet style gas cap both left and right. The left side cap is non-vented and the underside is ‘taller’ than the right side, vented cap. Caps are a larger, approximately 2.5″ diameter and have a domed top. OEM #s

61103-073a

for the left, non-vented and 61102-73a for the vented right side cap.
