I went through the same problem on a slabby Im currently fixing up. you can slide the circuit board out from the CDI box. look carefully at all the solder points, check for even the slightest, smallest of defects. My slabby had the same problem and wouldnt fire on cylinders 1 & 4, it turned out to be the white wire coming from the coil that goes directly to the CDI, the solder on the circuit board had a hairline crack. soldered it back up, now it runs like a new bike. look at a wiring diagram and verify that the power wire from the coil goes directly to the CDI
