CR26-33mm Special Carburetor Jet Needle (5-Clip Position)

Five clip positions give the Keihin N427-11Y needle its needle-height adjustment for small-body CR Special CR26, CR29, CR31 and CR33 carburetors. It meters the mid-throttle range, with Y profiles running from Y50 at the richer end to Y03 at the leaner end.

Select the required Y profile as well as the clip position. Moving the clip down raises the needle and richens the mixture; moving it up lowers the needle and leans it. This is the five-position family, not the seven-position N427-12Y.
