Japanese Bikes / Re: 1978 cb400a CDI interchange
« on: August 24, 2010, 06:22:20 PM »
Hey
I'm having the same problem on the same bike. I got a new coil, plugs, wire caps, battery and rebuilt carbs but the damn thing sputters at 30mph and won't go over. I suspect either the stator or the CDI. I think you can interchange them but not sure.
in answer to your question the only way to test is to swap it out for a different one (new perferably) and see if that did it. Where did you get the CDI's from? I believe the company that makes them in the states in Shindegen. You can google them and call to find out dealer info.
Hope this helps.
