We recently purchased a 1980 Honda cm400t. The original owner had been working on getting it to run and he thinks he narrowed it down to a cdi replacement. We bought a used cdi and installed it. When I push the start button, the lights dim a little but nothing else happens. I'm able to jump the stator with a screw driver and I can here the starter turn but I'm still not getting any spark to the plugs. Can anyone offer some insight?
