Designed by KEIHIN, a recognized brand in the world of injection and carburetors, it is aimed at discerning riders who want to achieve a clean idle setting, a more linear response to throttle opening, and reliable engine operation.
Usage: replacement or adjustment of carburetion on compatible Keihin carburetors.
Target audience: accessible to enthusiasts wishing to tinker in the workshop and to motorcycle maintenance professionals.
Practical advice: check the reference and condition of other carburetor components (needle, float, filter) before installation.
Installation: performed during disassembly of the carb body; prior cleaning is recommended to avoid clogging.
Before purchasing, ensure that the reference N424-14190 matches your carburetor model or your machine's manufacturer specifications. For precise adjustments, entrust the tuning to a technician or follow the manufacturer's original procedure to achieve a mixture suited to your use (city, road, track).
