Good To Know

Q: Can I install this CDI box myself? A: Yes, it connects to the factory harness, so basic electrical and hand tools are enough for most riders. Confirm your model and year before starting.

Q: How do I know my CDI box needs replacing? A: Common signs include no spark, weak spark, erratic rev limits, or an engine that dies without warning. Testing the ignition circuit first helps confirm the module is at fault.

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