Uh we'll? I'm also going to check for connections versus the wiring diagram to see what I can find, but I have no answer to tell if my spark is weak versus fat????

if you retard the timing a little bit, the engine will start easier..
the spark must look strong ... it does not real matter if blue or white colored ... i had the phenomenom that with one sparkplug blue spark and tryed another and made a white strong spark. performance on running mashine was no difference.. both plugs were brand new ngk br8 ecm
what is your actual jetting?? that could also bring some light at this point.
another reason could be to much compression, that the engine dont start. which head-gasket is installed the 0,5mm or the 0,25mm that was optional available from kawasaki?? a second base gasket would also help...
