DABAZUALY Ignition Coil Module 2-Pack for Kawasaki FR/FS/FX Engines — Replaces 21171-0743, Plug-and-Play

DABAZUALY's twin-set ignition coil assembly replaces worn OEM coils on Kawasaki FR, FS and FX-series 4-stroke engines to restore reliable spark and easier starts.

When a mower stalls, misfires or is hard to start, the ignition coil is a common wear item. These two replacement coil modules are built to fit a broad range of Kawasaki commercial and residential V-twin engines — including FR691V, FR730V, FR541V, FR651V, FR600V and multiple FS and FX models — and match the electrical and mounting points of the original parts so you can swap them without modifying the engine.

Which Kawasaki engines will these ignition coils work with?

These coils are compatible with many Kawasaki FR, FS and FX-series 4-stroke engines used on lawn tractors and commercial mowers. They cover both older and newer variants listed under common OEM replacement numbers, making them suitable for a range of machines.

• Fits FR-series engines like FR541V, FR600V, FR651V, FR691V and FR730V.
• Compatible with FS-series engines: FS481V, FS541V, FS600V, FS691V, FS730V.
• Supports FX-series models such as FX751V and FX801V.
• Replaces OEM part numbers 21171-0743, 21171-0711 and related KM part codes.

How do these replacement coils compare to the original parts?

These modules are designed to match the original coils in electrical output, mounting orientation and connector layout to ensure plug-and-play installation. They provide equivalent spark performance without the premium price of factory parts.

• Engineered to the same electrical specifications for reliable ignition timing.
• Same bolt pattern and connector fit as the OEM coils for straightforward replacement.
• Sold as two sets so you can service both cylinders on twin-cylinder engines.
• Constructed for typical outdoor engine conditions with durable housings.

What should I expect during installation and maintenance?

Installation is a basic mechanical job for anyone comfortable with small engine work. Remove the old coil, transfer any mounting hardware or brackets if needed, align the new coil and set the correct air gap per the engine service manual for optimal performance.

• Tools needed: basic sockets, screwdrivers and a feeler gauge for the air gap.
• Typical steps: disconnect battery, remove shroud, unbolt old coil, install new coil, adjust gap, reconnect components.
• Inspect spark plug wires and plugs while servicing for best results.
• Refer to Kawasaki engine manual for torque and gap specs.

How will replacing the coil affect mower performance?

A fresh ignition coil can resolve misfires, rough idle and hard starts by restoring a consistent high-voltage spark to the plug. While it won’t fix fuel or compression issues, it's a high-impact, cost-effective step when ignition problems are present.

• Improves starting reliability and reduces stalling under load.
• Smooths idle and improves throttle response when ignition was the issue.
• Helps maintain efficient combustion when paired with good plugs and tune-up parts.
• Two-coil sets ensure balanced ignition on twin-cylinder engines.

Who is this for: These DABAZUALY ignition coil sets are intended for homeowners, landscapers and small-engine technicians who maintain Kawasaki-powered lawn tractors, zero-turn mowers and commercial machines. They are ideal if you need an affordable, direct-fit replacement for coils listed under 21171-0743, 21171-0711 or related KM numbers and want a fast swap that restores reliable spark without custom fitting.
