Kawasaki Late-Model Cylinder Head Kit #2 99999-0674
The Kawasaki 99999-0674 Cylinder Head Kit #2 is a genuine OEM replacement cylinder-head kit for select late-production Kawasaki FX921V and FXT00V / FX1000V carbureted V-Twin engines.
This is specifically the #2 cylinder head kit. Kawasaki identifies Cylinder #2 as the oil-filter side of the engine, farthest from the flywheel.
Serial-number fitment is critical.
Use 99999-0674 only for:
- FX921V: serial numbers after FX921VA45905
- FXT00V / FX1000V: serial numbers FXT00VA46389 and later
This Kawasaki cylinder-head kit is for carbureted engines only.

What Is Included With Kawasaki 99999-0674?
Kawasaki's current cylinder-head kit guide identifies the late-model 99999-0674 kit as containing the primary components required to replace Cylinder Head #2.
- Cylinder head
- Cylinder head gasket
- Valve cover / rocker cover gasket
- Valve oil seals
- Intake valve
- Exhaust valve
- Valve spring seats
- Valve springs
- Valve spring retainers

Push rods are not included.
Kawasaki push rods 13116-0711 and 13116-0712 are serviced separately. Confirm the required push rods for the exact engine specification during cylinder-head service.
Cylinder #2 Means the Oil-Filter Side
Kawasaki uses specific #1 and #2 cylinder-head kits because the two cylinder-head assemblies are not simply treated as interchangeable service kits.
Kawasaki identifies the engine positions as:
| Position | Kawasaki Identification | Late Kit |
|---|---|---|
| Cylinder #1 | Fuel-pump side, closest to flywheel | 99999-0673 |
| Cylinder #2 | Oil-filter side, farthest from flywheel | 99999-0674 |
If the damaged head is on the fuel-pump side rather than the oil-filter side, verify whether Kawasaki 99999-0673 is the required late-model Cylinder Head #1 kit instead.
Late vs. Early FX921V / FXT00V Cylinder Head Kits
Kawasaki made a production change within the FX921V and FXT00V engine families. Selecting the kit by model name alone is therefore not sufficient.
| Application | Head #1 | Head #2 |
|---|---|---|
| Early FX921V through FX921VA45905 / FXT00V through FXT00VA46388 | 99999-0622 | 99999-0623 |
| Late FX921V after FX921VA45905 / FXT00V after FXT00VA46388 | 99999-0673 | 99999-0674 |
Do not substitute an early head kit for a late engine based only on appearance.
Use the complete Kawasaki engine model, specification and serial number to determine the correct cylinder-head kit.
Related Rocker Arm Kit 99999-0676
Kawasaki also lists 99999-0676 as the dedicated Rocker Arm Kit for Cylinder Head #2 on applicable late FX921V / FX1000V engines.
Kawasaki specifically identifies 99999-0676 as being for use with 99999-0674.
The rocker-arm kit is sold separately from 99999-0674.
Push Rods Are Sold Separately
The FX921V and FXT00V valve train uses separate Kawasaki push-rod service parts. The part numbers associated with this engine family include:
- 13116-0711 – Kawasaki push rod
- 13116-0712 – Kawasaki push rod
These are not included with 99999-0674. Verify both the engine serial range and applicable valve-train diagram before ordering related parts.
Why the Serial Number Is So Important
Kawasaki continued using the FX921V and FXT00V model families across a production change to the cylinder-head assemblies. As a result, two engines with the same basic model designation can require different head kits.
The serial number is therefore one of the most important fitment details on this product.
The engine model and serial number can be found on the Kawasaki identification label attached to the engine housing.
Before Ordering Kawasaki 99999-0674
- Confirm that the engine is carbureted.
- Verify the complete Kawasaki engine model and specification.
- Record the complete engine serial number.
- For FXT00V, verify serial FXT00VA46389 or later.
- For FX921V, verify a serial number after FX921VA45905.
- Confirm that Cylinder #2—the oil-filter side—is being repaired.
- Determine whether rocker arm kit 99999-0676 is also required.
- Verify push rods 13116-0711 and 13116-0712 separately.
