I just had one installed a month ago. Sort of an ECM for humans. I haven't healed enough to ride. However, I got a list of things to stay away from and one of them is a running engine. The list does not state if the concern is alternators or spark plug wires. It does not have motorcycles on the list. Since I am thinking more and more about getting back on my bike, I thought I would ask and see if anyone has any experience along the lines of is it OK to ride or not. I don't know anyone that even has a pacemaker, let alone anyone that rides. I have to learn about things that are good and not good.
