I had my ignition switch fail while running on my 85. The actual switch down on the column was bad and wouldn't stay in the koer position if i hit a bump. It was a t5 so i could just bump the key forward a little to fire it back up. Fouled my plugs a lot before I changed it.
So after all the testing and headaches it ended up being the ignition switch. After a few weeks the workhorse seems to be running at a premium again. so i thank everyone for there input and suggestions. back to hot nasty speed. now to figure out how to get more power to my pony
