i just went for my first ride of year and just got my jaws twin pipes on with a pure logic contoller. was having a great day until after turning out on my last pull up the mountain it was like someone shut off the switch on my sled. after coasting down the hill to a stop, i pulled a plug (which was a nice color of tan), i found no spark. i then rewired the sled back to stock and still found no spark. what is the porblem. I have never heard of a controller blowing the cdi box. anyone else have a problem like this. The sled ran great all day. it was pulling exactly 8000 rpms all the time. it was a little rough at low rpms, and took an extra pull to start, but that is just some fine tuning on the pure logic controller.
