Few Questions.

Well today I picked up a go kart and it has a Kawasaki engine on it what i'm wondering is.

What kind of engine is this? the engine number is kz550AE052553
Also is the firing order 1243?
And in what order are the cylinders?

Sorry that my first post is asking for help but this seems to be the best place to ask.

Looks like a KZ550, but someone will hopefully chime in that can confirm that and give some additional details.

Regarding the cylinder numbering, the Kaws are 1,2,3,4 from left to right when sitting on the bike.

By the way, post some pictures - we love pictures! :laugh:

No eBay APP ID and/or Cert ID defined in Kunena configurationit's a kz550-A3....

here is a link to a great book for it it is the factory shop manual....the best one.....and it is a fair/cheap going price imo....

Thanks both of you. I'll post some pictures when my friend comes over. Hopefully Now I can get the thing sparking right.

On the smaller 4's (I could be wrong) I believe the RIGHT ignition coil fires plugs #1 and #4 with #2 and #3 from the LEFT coil. On the bigger 4's is just the opposite with the LEFT coil firing #1 and #4 and the RIGHT doing #2 and #3.

The primary wires should be RED(going to both coils from the run/stop switch on the right handlebar) with either a BLACK or GREEN wire going to the coil(depending on how the electronic pickups are configured.

If the bike has the Kawasaki electronic ignition, the pickup coils are under a CD sized cover on the right side of the engine at the end of the crankshaft.

Well Its sputtering and popping. My friends dad said the timing is probably off. I wish I knew more about small engines lol.

The pickup with the black/blue wires trigger the spark for cylinders 1 and 4.
The pickup with the yellow/red wires trigger the spark for cylinders 2 and 3.

The pickup wires all go to the igniter box.

The 1 and 4 spark plugs are fired by the ignition coil with the black primary wire. (This coil would have been on the right side of the bike frame.)
The 2 and 3 spark plugs are fired by the ignition coil with the green primary wire. (This coil would have been on the left side of the bike frame.)

In order for all of that to work as it did from the factory, the pickup assembly and advancer/rotor assembly should be assembled as it came from the factory. (It often gets messed up after dissassembly for cleaning.)

Here's a link to the getting the pickup magnets correct and the rotor orientation correct:
