CR26-33mm Special Carburetor Jet Needle (7-Clip Position)

The seven-position N427-12Y needle gives small-body Keihin CR Special CR26, CR29, CR31 and CR33 carburetors more needle-height settings than the five-position N427-11Y. Choose the YY profile required for mid-throttle metering, from YY5 at the richer end to YY3 at the leaner end.

Moving the clip towards the needle point raises the needle and richens the mixture. Moving it towards the head lowers the needle and leans it. This small-body family is separate from the N427-51 used in large-body CR Special carburetors.
