    CT90 and Other 6V Ignition Intermittent Spark Fix

    Hey Y'all, I stumbled upon a revelation yesterday that I haven't seen posted anywhere as far as I know. I've been fighting both my CT90's for a little over a year, essentially they both would cut in and out at higher rpms both accelerating and running down the road. Turning on the headlight...

    Hi guys. I'm restoring a 1981 St70 Dax and since the original ignition switch is almost impossible to find, I got a1969 ct70 switch. I know very very little about wiring etc, but seeing the diagrams here, there seems to be a major difference on the switching arrangement between these two...

    Coil change and now no spark

    I have a 1971 CT70. The plug wire broke so I ordered replacement coil. I dropped the motor and changed it out. Now I'm getting no spark. I can feel a little zap from the plug when I touch it, but not enough to get a visible spark. Anyone ever run into this with after market coil and plug wire...

    1981 Z50R issues - weak spark

    Hi, I have a 1981 Z50R that my dad bought at a yard sale years ago. I rode it as a kid, then when I outgrew it, we parked it in our storage garage. Now, about 25 years later, I'm hoping my kids can enjoy this bike as much as I did. We pulled it out of storage, put in some fresh gas, checked...

    Futility of testing ignition coils?

My guess the problem is ohmmeter doesn't do a hundred tests a second while varying amplitude (and then count the passes), so almost-shorts are never...
