have a 2014 rsx 850i gator 500 hrs. always ran good till 2019. Now won't start in cold weather at all. (Under 40 degrees). Hard to start in warm weather. (even 75+) Once running won't accelerate without dying. Eventually warms up and runs with a few backfires? Continues to start once warm enough. Replaced spark plugs, fuel filter, fuel pump, wiring harness, air intake and filter, fuel line, and adjusted valve clearance. Still runs like crap till WARM! ?????? told to replace the integrated service module? Any help appreciated!

Have you checked coils? It is cheaper to buy some diagnostic tools than to start dumping money and hoping for the best.
