As an owner of a XJ900F, I have had my share of ignition problems as the bike ages and parts become scarce. I decide to dig deep and rebuild the PCB board of my ignition unit, I have way too many times replaced bits and the PCB board has become a mess. So here is my version, you must use the HA1825 and the HSA-10(B) board from the original. I have not done the mod yet, it will be sometime by the end of 2025 before I rewire the Bike, so “caveat emptor” if you decide to do this yourself from my information here (there might be some errors, who knows yet? it might just be absolutely correct.).

If you want me to make the PCB board available, just leave me a message, I will be getting a few in the next few months or so. Regards Arto.
