DKIIGAME Ignition Coil and Spark Plug Kit for Kawasaki FR/FX/FS Engines — Direct-Fit 21171-0740 Replacement, Includes Tools

If your Kawasaki-powered mower, generator, or commercial equipment is showing hard starts, inconsistent idling, or misfires, worn ignition coils and old spark plugs are common culprits. This DKIIGAME kit supplies two direct-fit ignition coils, matching spark plugs, and basic installation accessories so you can replace the aging components in one maintenance session and get the engine back to smooth operation.

Which Kawasaki engines will this kit fit?

The kit is engineered to match multiple Kawasaki overhead valve V-twin and single-cylinder engines used across FR, FX and FS series models. It replaces part numbers 21171-0740 and 21171-0711, making it an appropriate aftermarket alternative for those OEM references.

• Compatible series: FR730V, FX730V, FX691V, FR691V, FR651V.
• Also fits: FX801V, FX850V, FX751V, FX651V and FS541V, FS481V, FS600V, FX921V.
• Direct replacement for Kawasaki part numbers 21171-0740 and 21171-0711.

How straightforward is installation for a home mechanic?

This kit prioritizes simple replacement: coils are shaped to match OEM mounting points and spark plugs thread to factory specifications, so most technicians with basic tools can complete the swap. The package includes an adjustment tool and zip ties to secure wiring, reducing the need to source extras.

• Plug-and-play coil connectors align with factory wiring harnesses.
• Spark plugs match factory thread and heat range for correct fit.
• Included adjustment tool and four zip ties speed installation and wire routing.

What are the kit contents and why each part matters?

Replacing both coils and plugs at once addresses ignition system wear comprehensively: coils provide the high-voltage pulse and plugs convert it into spark. Changing them together minimizes repeat labor and helps restore consistent combustion across cylinders.

• Two ignition coils: restore reliable high-voltage output to the spark plugs.
• Spark plugs: ensure proper spark gap and electrode condition for clean ignition.
• Adjustment tool: helps set plug gap and seat components correctly during install.
• Four zip ties: tidy wiring and secure harnesses to prevent chafing or disconnection.

Will this kit improve performance or fuel economy?

Replacing degraded coils and fouled spark plugs can improve starting, smooth out idle, and reduce misfires, which in turn helps the engine run closer to its intended performance. While results depend on overall engine condition, fresh ignition components remove a common source of inefficiency.

• Reduces misfires that cause rough running and lost power.
• Promotes cleaner combustion for steadier throttle response.
• Minimizes repeated troubleshooting by addressing multiple ignition parts at once.
