CR35-39mm Special Carburetor Jet Needle (5-Clip Position)

Keihin N427-38 is the five-clip-position jet needle for large-body CR Special CR35, CR37 and CR39 carburetors. The 3865, 3867 and 3869 profiles run from richer to leaner within this group, with part numbers N427-38A00, N427-38B00 and N427-38C00 respectively.

Clip position changes needle height for mid-throttle tuning. This family does not fit small-body CR26 to CR33 carburetors, which use the N427-11Y or N427-12Y needle series.
