This product has a low defect rate, but a high return rate from customers: Either clients are buying it to resolve a spark issue that is not caused by the CDI box, or they are buying the wrong part for their make model and year.
Before purchasing, please make sure to follow our advices:
- Always double check our pictures & fitments against the part you physically have on the vehicle (Our pictures are accurate).
- If you are buying this part for spark issues: these vehicles are notorious for stator failure, please make sure you have properly tested the stator before purchasing.
- Clients are buying this part for performance: Great add-on with an aggressive timing curve and increased rev limiter.

Please note that: The only real way to test your CDI box is to swap it out with another known good unit from the same year/make/model. Because of this, we recommend that you rule everything else out before replacing the CDI box.
Our CDI may use a different wire color code than your original.
All the wires are installed in the correct order; please do not change any of the wiring configurations.
This CDI is designed as a direct plug-in replacement and should be used as such.
