    Polaris Hurricane 700 and Yamaha XL700 run great then start bogging and die

    Hi, I have two skis, a 1997 polaris hurricane 700 and a 2003 yamaha xl700. They both start easy and run great for the first 4 minutes. Then they start cutting out, bogging, and randomly dying. They start right back up and then they run great again after letting idle for half a minute. Then after another 10 minutes of running great they want to bog and sometimes die, go slow, lose acceleration, etc... Its really just random and off and on. Also, there is white milky fluid coming out of one of the carbs on the hurricane. Im assuming they both need rebuilt carbs, but i just want to check with this great forum and get thoughts before i do. Thanks!!

    Before rebuilding them, I would ensure their airflow isn't restricted. My Kawasaki is designed without an air filter, and my Polaris's both have air filters.

    The Polaris units have spark arrestors, not air filters.

    I want to say they look like air filters, they are metal mesh with with filters on top of the carb

    But they both look pretty clean and like nothing is restricting them

    White milky fluid is a mix of water and oil. Stop running it and inspect the oil injection system, from the tank to the pump to the carbs, including all lines/

    How long have you owned these machines?

    Have they ever worked properly for you?

    It sounds like you have water inside the engine. If so, that is not a good thing.

    Not very long, I bought both this past winter and am now starting to work towards getting them ready for summer. From my understanding the hurricane only has 30 original hours on it, the owner just let it sit outside in the sun most of the time. The yamaha has been stored indoors and regularly winterized according to the previous owner.
