CB400A/CM400A/CM450A Hondamatic CDI [Plug and Play Unit]

Hondamatic Plug and Play CDI.

All resistors are AEC-Q200 automotive rated for high reliability. 1% tolerance resistors are used, with the exception of a few values that are not available in this configuration. In that case they are 5%.

Capacitors are high quality and made in Japan, just like the original.

New wiring harness with new Hitachi connectors and correct colour codes.  Crimped with the proper tools for reliability.

Brand new, custom made galvanized steel powder coated case made locally in York, Pennsylvania, U.S.A.  This case looks like the original, and fits exactly like the original.  The only difference is our case is an inch taller to allow additional room for the components and potting compound as this was a failure point on the originals.  This is unlike our competitors unit, which is mounted on a bracket with plastic case that is zip tied to the bracket and does not allow room for removing the valve cover.

CDI is hand soldered, assembled, and tested by me in the U.S.A. No work has been farmed overseas with the exception of the PCB which is from a reputable vendor in China.

Check your stator and change relay before ordering to determine they are not faulty. Instructions are available on the VHT Forums.

Shipping is flat rate priority from USPS.  If you are international please E-Mail me to discuss shipping options.  Weighted shipping options to international will become available over the next few weeks.

Reviews

“If you have a Hondamatic with ailing ignition, there is an answer. NO compromise, NO modification. Plug and ride, just the same as the original. ” – Rod F. at VHT

“It is a great handcrafted product, and lots of care went into the order. The seller was very communicative throughout the whole process. I would buy from again!” – eBay

“Thanks for supplying me with the CDI for my 1978 CB400A, without it, all these parts are nothing but a door stop. The quality is excellent as this is not just a backyard mecanic jobby. This is a thought out specialised piece of electronics. Better than the original and constructed to last. Worth the bucks. Thanks.” – Rob G. at VHT

“I installed the CDI last night and it solved my issue. I’m surprised how much the hondamatic feels like a normal bike.” – Jacob M.
