Sons 2004 100f shuts off after 45-50 minutes of riding. Initially thinking it was flooding as letting it sit for 10-20 minutes it would restart. However, after fully rebuilding carb, double checking float, and watching his GoPro footage I’m leaning more toward electrical. It basically acts like the kill switch is being held because you can basically hear it stop firing and coast to a stop. I’m assuming the coil is going bad and over heating.
Is there a way to bench test the coil and CDI to see if one or both are bad? I hate throwing parts at problems without first knowing if they are bad or not.
