Hello Forum. I recently purchased a 2005 Sportsman 700. Although, at 70 years old, this is my first ATV, I have owned or worked on everything from model airplane engines to army tanks. Anyway, my Sportsman is in very nice condition and I have ordered a Service Manual, cleaned the filter, greased the fittings, and changed all the fluids except the engine coolant (I’ll get to that soon). However, I now notice that the "Check Engine" light is on when running. I don’t think it was on when I bought it, but can’t be sure. Diagnostic Mode indicates failure codes 41 & 45. Has anyone had any experience fixing these?
TIA, Rod
