Hey all, I have not been on in a while but love this site for all the info! I was just wondering about EFI vs carbureted wheelers. I have a 2013 sportsman 500 that is carbureted and now when I start it cold it is very hard to keep running. I will be honest and say that I have been running 87 octane in it for it's whole life. I would assume that the carb is gummed up now and that I need to un clog it. Is there anything I can do to clean out the carb and make the wheeler run better with out taking it all apart?? It still runs ok once warmed up but it's really hard to keep it running for the first few min of first start up..
