1994 FZR600R running on cylinders 1&4 but 2&3 aren't firing, Am I forgetting something? My motorcycle starts but I have to keep the throttle rolled on or else it'll just die, I've checked all the wires and installed a new harness a week ago, the bike starts up and I'm getting suction from all four carbs, but the third and second cylinder isn't firing and there's no spark for the third cylinder, the first ignition coil is doing nothing while the coil for 1&4 has a spark. The coils are also relatively new. The CDI box is fairly new as well but when I took it to Yamaha dealership they told me that one of the terminals in the box might not be sending a signal to the coil to tell it when to fire, so it just sits there waiting for a signal. should I get a new CDI box? @
