MY Sportsman 700 2008 sounds like it loses power periodically. Doesn't happen when I take into shop, so no one can tell me what it might be. It doesn't die, it just sputters some, kind of like there isn't gas getting to it. A shop said they cleaned fuel tank, but I found out they cannot be trusted. Any ideas would help me a lot.

 

Read the "sticky threads" in this section about sensor wiring and problems,could be why its an intermittent problem? T-bap repair kits were what I had to replace the most on the 700 and 800 efi systems. Sometimes the atv would run good,other times not.You can also check the small wiring from the throttle body sensors for chaffing or broken wires. OPT
