The vintage MX bikes are still popular. The 40+ year old electronics used in the OEM CDI are not so popular. They failed frequently and did not get better with age. We have experience with the MX bikes from the 70’s, having owned & raced many at that time. The FIREPLUG CDI is a modern ignition box replacement for the Vintage YAMAHA MX motorcycles. The FIREPLUG CDI uses the latest technology to increase spark energy and improve overall performance over the OEM CDI. Included is the FIREPLUG CDI reliability and warranty that has become the GOLD standard with our ignition modules. Nobody matches our reliability or warranty.

NOTE: It is always good practice to check / verify the ignition timing & carburetor jetting whenever making changes to your engine. The OEM CDI spark energy will have weakened over time. Weak spark will tolerate too advanced timing & very lean jetting. Once you have good spark energy, you may find the bike really responds to larger jetting with improved performance. More fuel equals more power! Verify timing & adjust as needed for your style of riding. Always best to use factory timing as starting point, then adjust from there.
