Working on a issue that I had at the end of last year with my 2018 850 with a MPI turbo. Sled performed perfect for the first 250 miles or so but then started throwing a detonation code the last few rides. It would put sled to a idle instantly. This would happen only when I would hit the throttle hard. If I rolled into it gently it would spool up and run perfect. I had the codes looked at and it showed a lean code on mag side once. I have looked over all the wires and fuel lines and everything looks fine. I was wondering if this could be a clutching issue. Just want it to go back the way it was!! Sled only has 400 miles on it.
