hi my 2002 sportsman 500ho stalls after riding a bout 10min. IT backfires and wont start until it cools.I cleaned tank, carb and air filter. any suggestions thanks

 

Welcome! First thing I'd check is that the tank vent hose isn't pinched that could cause fuel starvation until it has a chance to get another "gulp" of air. Just blow through the hose going into the pod area with the fuel cap off. You should be able to hear the hiss of air if open. Another problem could be trash build up in the fuel filter, or trash in the fuel pump or pump itself is weak on fuel flow. Just disconnect the fuel line at the carb and crank the engine over,there should be a pulsating stream of fuel. Also the 3-way fuel valves themselves can get stopped up over a period of years. I have found all of these conditions at one time or another. "IF" everything is good in the fuel supply,you could have an electrical problem that acts up when warm. Stator getting weak from heat, a cdi,or coil problem. Eliminate the fuel supply as a problem area first. OPT
