Vintage BMW Motorcycle Owners

I just tried to upload a huge PDF file and got a message that said it was too large. If you didn't get any messages, then I'm not sure. What was the size of the file you tried to upload? I could find something I have around the same size and see what happens to me.

When the points open, the primary coil field disappears, and the secondary coil collapses and the v...
