Mikuni Carb Jet Hex Head 440

Whether you are looking to rejet your carbs after fitting an aftermarket exhaust or air filter, or simply want to replace old blocked up jets, these Keihin replacement jets are an affordable way to improve how your motorcycle runs. If you notice your engine not running well at or close to full throttle, chances are you need to change your main jet.

Please Note: Re-jetting your carbs requires some knowledge of how a carburettor functions. We strongly recommend double checking the carb jet size and style you need before ordering. Refer to the air/fuel recommendations within your motorcycle service manual for the OEM specifications.
