What dimensions do you want

What dimensions do you want to know? I have the original coil out of my R69S since I replaced it with an Emerald Isle coil.

Dimensions

To be honest I need al the dimensiones you can measure. For example the iron core is also the mounting part and that is the most important mesure that I need. Also, the diameters of the coil on the big side shims. I will make a diagram and I will post it here.

This below should be the diagram of the coil, I need the dimensions you actualy see in the drawing: lenght, wide, diameter in order to fit in the mount after the coil is ready.

Coil dimensions

I have a few bad coils
I would be happy to send one but the shipping cost would be expensive

No bike garage or bmw service shop in your area that could have one or somebody with r50-r69s bike you could use ??

Here's what I got so far. I

Here's what I got so far. I guess you can say that all of the dimensions are "about" as in about 72.9mm. There's going to be slight variations depending on which side you measure.
