Yeh I am stumped too if you have the left coil sparking 1 and 2 and the right firing 3 and 4. My haynes and Clymer manals both show the left coil firing 1 and 4 and the right 2 and 3. Also what year is your GSX550? If it is an 83-86 then the primary wires going to your coil leads should be; for the Left Coil: 1 white and 1 orange/white. For the right: one wire Black/Yellow and the other orange/white. It should't run, but backfire if you have the leads hooked up other that the above.
