Coil exposure/cooling shielding

Factory points have approx. 50% duty cycle. Each coil has about a 50-50 chance of being on when the key is on and the motor is not turning.

But anytime a part has a 50-50 chance of going in wrong, it will do it 100% of the time. Three semesters of engineering statistics and I can't explain it....:laugh:

Also, anyone who has done the relay power to coils mod, will have a "100% on" duty cycle with "key on".

I've seen coils that had small copper heatsinks glued to them with thermal transfer epoxy, and it had great results. It kept them nearly ten degrees cooler. Heatsinks are superior to fans, and even better when used in combination. But those coils were square and bulky, not like the round dynas on my bike.

Final verdict - ride faster!

Not sure if this was meant as a joke. But the coil mod won't affect the coil's duty cycle. The duty cycle is determined by the points or electronic ignition system.

With the factory electronic ignition, the duty cycle is 0% when the motor is not turning.

I love the calico with cattitude.
