Good To Know

Q: How do I know if my ignition coil needs replacing? A: Common signs include hard starting, misfires, or a weak spark at the plug. Testing the coil with a multimeter confirms whether output has fallen out of range.

Q: Can I install this coil myself? A: Yes, the coil connects at the factory wiring point and mounts in the original location. Basic mechanical skill and a service manual are enough for most riders.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
