Uncategorized What year did the 850s start throwing the timing key? August 15, 2016 dstech When I had my 2010 850 we did not ever hear of the timing key issue or really any motor problems with the 850s. I see a lot of threads about these types of things now. Did the problem start in 2011 when they moved production to Mexico? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
