OEM housing OPTION:  For some, it is desired to re-use your original Hitachi OEM housing.  We have the capability of integrating the FIREPLUG CDI electronics into the OEM hitachi aluminum enclosure.  From the outside, the CDI appears OEM.  This keeps the sleds stock integrity for shows etc.  The real difference however is with the FIREPLUG CDI internals, your SR will actually have spark & run!  This service is a $35 cost adder.
Contact us direct to inquire about this option.

DESIGN BACKGROUND: The FIREPLUG CDI is a high-performance replacement ignition unit for your Vintage Yamaha. Other improvements from the original Hitachi CDI is the elimination of the rev-limiter, which the Hitachi CDI utilized to stop over-revving. This was a huge disadvantage for modified engines, as the maximum RPM was limited by the CDI box. The FIREPLUG allows the engine builder to determine the RPM range. The FIREPLUG CDI provides a higher-energy output. This translates to quicker starting, quicker throttle response, stronger pull & cleaner burning combustion.

The FIREPLUG is manufactured using the best available industrial-grade components. The FIREPLUG is not a high-volume / mass-produced imported device. It doesn’t exist until an order is received. Ask anybody currently running our FIREPLUG CDI ignition unit.

There is not a better CDI available…period!
