Intake Manifold Carb Holders for Kawasaki Z1 KZ900 KZ1000 | 16065-028 16065-029

Product Overview

Restore a secure and properly sealed connection between the carburetors and cylinder head with this replacement intake manifold carburetor holder, designed for compatible vintage Kawasaki Z1, KZ900, KZ1000, KZ1000 LTD, Z1-R, Police 1000, and KZ1000 Shaft motorcycles.

Years of engine heat, vibration, fuel vapor, and age can cause the original carburetor holders to harden, crack, shrink, or lose their ability to seal properly. A damaged intake holder may allow unmetered air to enter the engine, potentially causing difficult starting, unstable idle, hanging RPM, hesitation, inconsistent carburetor synchronization, or a lean-running condition.

This replacement is designed around Kawasaki OEM references 16065-028 and 16065-029.

Kawasaki uses two different carburetor-holder positions:

• 16065-028 — Right-Hand Carburetor Holder
• 16065-029 — Left-Hand Carburetor Holder

A complete four-cylinder installation normally uses two right-hand and two left-hand holders.
