I have a 72 CT70 with 110cc clone engine

It is the kazuma style that has the ignition coil and stator mounted inside the side case

This is the second ignition coil I have put in, and after ~500km the ignition coil is open. On the left hand terminal you can see where the wire is broken, this is the second failure and is identical to the first.

Has anyone experienced this before? To me the wire guage is larger on the good side than the side that breaks. I was able to solder a bridge in place but I wonder if this is a design problem.

Any ideas? Does anyone have a source for a good quality coil / stator for this type of engine?

I have read on this board many times by those with more experience with these engines that you want true "Honda" on this one. A coil should not go bad and I've seen these things after sitting for 20+ years and the coil is still good. Bite the bullet and buy a OEM Honda coil. IMO

The Honda coil will not fit in place on this engine

The bolt pattern spacing is incorrect. I also wonder if it would pickup correctly as the physical size is different

Cost is not the issue, I would glady pay whatever I need to for a good quality piece that will fit this engine

I am happy with the engine otherwise, just the re-occuring ignition coil issue
