your problem sounds more like a ignition switch.. check that.
sounds dumb.. did you try replacing the spark plug?

Check the fire coming from the stator, and then check it coming from the pickup coil. This will tell you if your even getting spark to the cdi.

What CDI did you replace it with? Was it stock or was it a procom? If it was a procom then there is a good chance that it has gone bad again cause they are junk. Also if its a procom CDI your battery has to be in tip top condition, if its a weaker battery the procom will be a bastard and decide not to work.
