Looking for advise here. I have a 2015 Sportsman 570 with about 50 miles on it and the other day it started bogging down and backfiring while out in the field. I managed to get it back on the trailer before it really crapped out, thankfully. Right now it barely idles and if I get it running and rev the motor it will back fire and spit and sputter. I changed out the sparkplug, pulled the fuel rail and injector out (they looked clean no gunk), the spark plug was fouled. After that I took it for a spin around the neighborhood and it ran like crap, backfiring and falling on its self.
About a week ago I put a new tank of gas in it, so of course the tank is full! I am thinking that it is a gas/gas delivery problem. My next step is to drain the tank and blow out the fuel line and pull the fuel pump to see if there is any gunk blocking the flow of fuel...
Anyone have any thoughts or suggestions?
Thanks
John
