    Hey everyone! I have a Honda CB400A. And lucky for me, my CDI unit went out. As you all know, the CDI units on these bikes are famous for going out. So I’m getting a new one. The only problem is that new CDI’s for this bike are incredibly hard to find. And IF you happen to stumble across one...

    Recently bought a 1978 cb400t II. Bike is really low on power and upon checking for spark I saw it was very weak. I've gone through and tested the coil and stator and the only thing not in spec is the advancer pickup sensor. Ant help or advice is much appreciated. Pretty new to a bikes...

    I'm presently trying to figure some things out and make this work in my favor. I believe it can be done with sufficient help. IE, LDR or Sonier, since they seem to know a lot about wiring on hand. This is the write up I was looking to Trying to compare wiring diagrams but I can't seem to find...
