I purchased a Baja ZS167FMM dirt bike a few weeks ago. No spark. I was told the stator was bad. I double checked voltages, and resistances, they all read okay, except for the timing sending unit. I still ordered a New Stator 6 pole found on Amazon from PCC Motor, $36.00 shipped. I installed the stator and pickup. Same problem. Then I noticed there was very weak magnetic field from the flywheel pickup magnet. I am thinking this has got to be the problem. I am an old motorcycle enthusiast and have rebuilt quite a few bikes in my time, but this is the first time I have encountered this problem.
Any thoughts are appreciated.
