Brand new to site and new to Polaris. I have a 2009 Sportsman 500 H.O. LE with about 11 hours on it, bought new and have only had the quad about 3 months. Issue is quad will stall and not re-start when there is still about 1 - 1 1/2 gallons of fuel yet gauge will indicate 1/2 tank of fuel. Brought back to dealer and it did the same thing when I went to pick it up. Both times filled tank with fuel and then it ran fine. They replaced the gas tank and mechanic says he has never seen or heard of this problem. He said he was going to email Polaris to see if any other reports of this. If I got a 4.1 gallon fuel tank I don't want to have to haul extra fuel to get it to run if I still gor fuel in the tank. Any suggestions or help is appreciated.
