    Are there flames from both carbs or do you just have a single?

    OK, we can assume the cdi is not at fault. You have alreay verified the flywheel key is not sheared. The stator has been rebuilt but let's verify it's working properly. Let's get Excitor, charging, and trigger ohms.....AND with plug wires grounded and everything hooked up backprobe the connector and give me AC voltage readings of those 3 while cranking it over.

    Re: 96 Kawasaki 750sxi flames under carbs in intake

    I changed the cdi boxes 4 or 5 times in attempt to solve my issue and now I only have spark on one plug. At that point I took a break over the holidays and am back trying to resolve this back fire issue.
    I will check values and post them in the next few days.

    That's what things are leading to, a twisted crank. I hope not ,because I just rebuilt the motor.
    I was going to put a dial indicator in the spark plug hole and try to measure crank twist. Not sure if I could tell. I will post outcome.

    Did some checks for no spark on one spark plug
    Ohms between spark plug caps 17,760 ohms
    Stator was rebuilt and measured this at plugs, I think stator is fine
    Blue/green 484 ohms
    Red/purple 399 ohms
    Brown/brown 1 ohm

    I attempted to measure crank twist. I think it’s about .015. I had trouble with this.

    You need a Degree Wheel or mark the Flywheel or PTO Coupler at Top Dead Center for the Number 1 Piston (Front).

    Then put the Number 2 Rear Piston at TDC. Read the Angle; it should be 180 degrees.

    You can also use a Digital Inclinometer like this one:

    I picked up a degree wheel and made a fixed marker/pointer at 180. I inserted the depth gauge and rotated the crank another 180. I measured no twist on the crank. I do have .005 difference of depth from TDC between cylinders. The rear cylinder is .005 lower at TDC than the front one.
