My kid has an SXI pro that got water in the Ebox and quit. I took it apart and replaced the coil/plug wire assembly and the wire fittings into the ebox. It ran great for a while, maybe an hour or so but now it will run on both cylinders for about 1 to two minutes and then starts missing on one cylinder. Ny instint tells me that the new coil I have is faulty but I am looking for a bit of advice from anyone with Kawasaki experience? Another Question, can you run these things out of the water? Connect a hose somewhere and test run it? It would be nice to let it run for a while and experiment with some things to see if I can isolate the problem.
