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.

Dedicated vintage Kawasaki replacement catalogs list these 16065-028/029 holders across the Z1, KZ900 and early KZ1000 families above.
Exact market specifications can vary, particularly on late-production or regional KZ900/KZ1000 models. Confirm the OEM number and physical dimensions before ordering.
OEM Cross-Reference Numbers
Right-Hand Carburetor Holder
- 16065-028
- 16065028
Left-Hand Carburetor Holder
- 16065-029
- 16065029
Kawasaki factory diagrams identify the two components separately as:
- Holder, Carburetor, R.H.
- Holder, Carburetor, L.H.
For example, Kawasaki specifies two 16065-028 right-hand holders and two 16065-029 left-hand holders on the 1976 KZ900-A4.
The same LH/RH arrangement appears in KZ1000 applications such as the 1979 KZ1000 LTD.

Measurement Note
The supplied product measurements are:
- 29.32 mm / 1.15 in inner diameter
- 56.78 mm / 2.24 in mounting-hole spacing
Professional replacement catalogs commonly specify approximately 32 mm internal diameter and 58 mm bolt centers for OEM-style 16065-028/029 holders.
This difference may result from:
- Different measuring locations
- Inner lip versus main bore measurement
- Center-to-center versus edge-to-edge bolt measurement
- Aftermarket manufacturing tolerances
Use the dimensions shown in your actual product photos as the final reference.
Important Package Quantity Note
The original Kawasaki four-cylinder installation normally requires:
- 2 × Right-Hand Holder — 16065-028
- 2 × Left-Hand Holder — 16065-029
A complete replacement kit therefore normally contains 4 carburetor holders. Vintage Kawasaki replacement kits are commonly sold in this 2 RH + 2 LH configuration.
If your SKU contains only one manifold, clearly identify whether it replaces:
- 16065-028 RH, or
- 16065-029 LH
Do not advertise a single physical holder as replacing both positions unless the aftermarket design has been specifically manufactured and verified to do so.

Fitment FAQ
Will this part fit my specific model and year?
This intake-holder design is commonly used on compatible:
1973–1975 Kawasaki Z1 / Z1-A / Z1-B
1976 Kawasaki KZ900-A4
1976 KZ900-B1 LTD
Selected 1977 KZ900-A5
1977–1980 KZ1000 A-Series
1977–1980 KZ1000 LTD B-Series
1978–1981 Police 1000 C-Series
1978 and 1980 KZ1000 Z1-R
1979–1980 KZ1000 Shaft / ST
Your motorcycle should use 16065-028 and/or 16065-029, and the original holders must match the mounting pattern, intake opening, vacuum-port arrangement, and physical shape.
Do I need to match the OEM part number?
Yes.
Kawasaki uses two separate numbers:
16065-028 — Right-Hand
16065-029 — Left-Hand
A complete four-cylinder installation normally uses two of each.
The OEM numbers should therefore be matched together with the position of the original holder. Do not assume the left and right parts are identical.
What models or situations does this part not fit?
This intake manifold is not confirmed as a direct replacement for:
Later KZ1000/KZ1100 models using different 16065-series holders
Fuel-injected KZ1000G Z1 Classic without modification
Kawasaki GPZ1100 models using different intake holders
Modern Kawasaki Z1000 motorcycles
Kawasaki ATVs
Kawasaki dirt bikes
Go-karts
Scooters
Engines using a different mounting-hole pattern
Motorcycles with aftermarket carburetors requiring significantly different intake dimensions
Modified cylinder heads with different intake-port spacing
Do not assume that every Kawasaki 900cc or 1000cc motorcycle uses these holders.
