Old Guy Too Many Bikes
Well-Known Member
Went for my weekly ride on my 140 powered CT70 today. Flying down a two lane at about 55 when the engine just died, like the key was turned off. Got it home thanks to the wife and the Honda Fit. Motor still has compression, but no spark. Swapped out the coil and plug from my other bike and tested fine. Figure maybe the CDI unit went bad. Ordered a replacement just in case. Does this happen often? Motor has about 4000 trouble free miles. If it's not the CDI unit, what could it be? The pulsar magnetic pickup and the flywheel look good. Maybe the coil wire grounded out somewhere. I never wired the emergency kill switch. Can I hotwire the coil right to the battery to bypass the ignition switch? I know my way around points, but never had any electronic ignition issues or experience. Any help would be appreciated. I also have a YX140 powered CL90, but getting to the CDI means dropping the engine out, but I could swap out most any other part.
