I am finally getting a start on my zx750. My bike did not come with any of the wiring in and had no ignition leads. Got my leads but have no idea which leads goes where. Is it 1-2-3-4 left to right or what.
Bike has been on fire so some stuff is melted and I can get that fixed. If I can get this to work then I will be know to continue building this thing.

Sitting on the bike, it is left to right. one coil goes to 1 and 4 the other goes to 2 and 3. not sure of primary side colours, try googling images for wiring loom pics, sometimes get good results.

firing order is 1-3-2-4, they use dual coils 1-3, 2-4 --- the majority of 4 cyl bikes fire on compression and exhaust stroke. Therefore, there are two sets of pick ups, one CDI, two ignition coils and 4 spark plugs. When cyl 1 is on compression it fires and cyl 3 is on exhaust stroke there is spark too and visa versa. Putting it simply there are two ignition coils connected to GDI unit. One coil ignites cyl 1 and cyl 3, the other coil ignites cyl 2 and cyl 4.

made a mistake-- firing order for 4 cyl bikes is 1-3-4-2
