I have a 2019 Summit 850 that often cranks over excessively before starting when the engine is warm, particularly if I ride constant throttle for some time. The dealer says the sled is throwing code P2147 and they have replaced the spark plugs, both injectors, and are now looking at the crank pos sensor. I am looking for any feedback or advice as I want to get back on the snow as soon as possible! Note: The sled is running the original exhaust & spark plugs are indexed correctly

Did they check compression to verify the engine is healthy?

they never mentioned it. The issue is very intermittent, sometimes it may not happen for 10-15 hot starts, and some more times it may happen every time for 10-15. The machine performs as it should once it starts, and if it does the long crank and you shut it down instantly it usually starts instantly on the 2nd attempt... Alsomt seems to be more of an electrical issue than a low compression type of thing..
