Looking for 95' CB400 wiring diagram

Post by JamieCB400 » Tue Oct 06, 2015 8:47 pm

My bike has a mid rpm range constant misfire which I believe is related to the 180kph restriction.

Fitting the resistor in the speedo made no difference.

The loom looks like it has been messed about with so I was looking for a wiring diagram for the bike.

I managed to get hold of the translated version of the manual but the quality of the wiring diagrams are too low to make out the colours.

Is there a higher quality manual out there or am I out of luck on this one?

Should be the Blue with orange trace on the Ignition module. You need to solder a 2k ohm resistor between it and the black with white trace wire , the blue/orange can be cut but the black/white just needs a small part stripped off it. Remember to tape it up well.

Thanks for the reply. I have a Black and White and an Orange with Blue trace (The one that runs to the speedo).

Anyway, I fitted the resistor between those with no difference, although the Black and White wire had already been cut and rejoined with the alarm wired through it.

I tried pulling the resistor for the clocks before changing anything and it made no difference to the misfire.

When riding it feels more like a bad flat spot than it does a misfire. It is only between about 5500 and 7500 rpm.

This post explains it best.
