  1. 110 EFI Hard start/flooding

    Polaris Outlaw
    Hello all, My son's 2017 110 EFI started to become harder and harder to start. Once started seems to run fine for the most part. It seems to be flooding out at start up as you can smell gas heavily at the exhaust. Would a dirty injector cause this issue if it were stuck open? Has good spark...
  2. Very hard to start? (cold start)

    Polaris Sportsman
    My 14 Sportsman 400 was very hard to start yesterday. I keep it in my garage, however my garage isn't heated. I was expecting it to be a little more difficult but not that bad. It was 12 deg f outside and probably 20 in the garage. So my question is what do some of you do when it gets cold...

  7. Fuel in Oil

    ATV Repair and Maintenance
    Hey Guys, I cleaned the carb on my 98 Magnum 425 about 3 weeks ago. It ran great for two days then it became hard to start. I checked the oil level and the first two days it was good. Then when it became hard to start the oil level started to go up. The oil does not really smell like fuel, but...

    ATV New Members
    Hi there, I have been a fan of this site and have been a "lurker" for a while but now I am finally in. I have a 1985 250 trailboss that has a weak spark and no power to the head lights and taillights. Looks like the stator but I went to pull the flywheel off and I now have question. It looks...
