Product Description
The Genuine Kawasaki 12004-0793 intake valve is a precision-engineered OEM component designed to control the flow of air and fuel into the combustion chamber on FR, FS, and FX series V-twin engines. Its primary function is to open at the correct time to allow the air/fuel mixture to enter the cylinder, then seal tightly during compression and power strokes. The 49078-7002 valve spring provides the necessary tension to close the valve properly and maintain valve train stability at high RPMs. Over time, intake valves can become burnt, warped, or worn, and valve springs can lose tension due to heat cycling. Common symptoms of valve train issues include loss of compression, hard starting, rough idle, backfiring, valve float, or reduced engine power. Replacing both components together ensures proper valve sealing and operation, restoring reliable performance for your mower or turf equipment.

Frequently Asked Questions
Q: Why should I buy the valve and spring together?
A: Valve springs lose tension over time due to heat cycling. Replacing both together ensures proper valve seating, prevents valve float at high RPMs, and saves you time and shipping costs compared to buying separately.
Q: What is the difference between 12004-0793 and 12004-0740?
A: 12004-0793 is the updated OEM replacement that supersedes the older 12004-0740. Kawasaki released this updated part number with potential engineering improvements.
Q: What are common signs of a bad intake valve or weak spring?
A: Common symptoms include loss of compression, hard starting, rough idle, backfiring through the carburetor, valve float at high RPMs, or reduced engine power.
Q: Should I replace both intake valves on a V-twin engine?
A: Yes, it is recommended to replace valves in pairs (both cylinders) to ensure balanced performance and compression. You would need two of these bundles.
Q: What valve clearance should I set after installation?
A: Typical intake valve clearance for these engines is 0.006″ (0.15mm) when cold. Always verify with your engine’s service manual.
