Needle valve for the Keihin carburetors as used on, amongst others, the Honda CM400 dating from BEFORE 1980.
This needle has a Viton-tipped for superior sealing qualities.
Replaces the following Keihin part numbers:
- 16011-169-004 superseded by 16011-GBF-B41
- 16011-393-004 superseded by 16011-KCK-910
- 16011-382-004 superseded by 16011-KG0-891
Although these carburetors were originally delivered on the above mentioned models of motorcycles, they are often transplanted onto other bikes and engines so the range that these diaphragms might fit is much broader.
Alternatively, your bike might have been equipped with different carburettors during its life so please verify that the needle shown will fit your bike.
