Hi Dom and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, a little more background info please:

  • • has it been in storage for a length of time;
  • • was this issue slowly developing while in use;
  • • or suddenly / just now;
  • • any recent upgrades, new parts (other than the battery), work, repairs or mods done to the Polaris ?

not exactly in storage but not a lot of use. started and driven about once a month since owned. About mid August I tried to start it and the issue had arose. I originally thought the battery had been damaged because it sat long enough to go under. I just now got a chance to try to work on it. So I purchased a new battery and installed it today before any other service activity.
Since August, the bike has been kept outdoors about 50% of the time. No mods or upgrades.

I understand.

Let's try the basics:

  • remove the spark plug;
  • pour a teaspoon of 2-T oil through the spark plug hole;
  • thread back in the spark plug just a few turns;
  • allow to soak for an extended period of time even overnight;
  • remove again the spark plug;
  • attempt to start.


Please post back results / observations of the above once tried.

I got delayed by the Holidays. I will install the 2T oil tonight, will know if it is a solution by End of weekend. I am assuming that you are thinking that old or bad gas seized a lifter or something. I will also verify if the engine (Valve, piston or whatever). i'll let you know what I find. Thanks.
