kawasaki 1984 gpz 1100

hello everyone my name is george
i ride a kawasaki gpz 1100 1984
i have a problem with the ignition system
spark plugs 2 & 3 fire but 1 & 4 dont
all leads and coils are good and pick up coils are brand new
stator good
retifyer good
igniter good
if anyone can help thankyou

PS sorry about the spelling

May be a fault in the tacho wiring- it is run off the coils. Check the switch that switches between voltgauge and tacho. (if it has one.)

Check your earth where the coil bolts to the frame. It has to be good.......but the problem sounds to me like a faulty coil.

Have you tried swapping the ignitor leads from 1&4 to 2&3, and the plug leads ? This is a good test for coil operation.
