Was out riding for 2 days. 3rd day, we rode for about 15 minutes. All the sudden, the machine just died.
It is a 2009 Polaris Dragon 800 with a boondocker fuel controller and turbo.
Had it about 5 years and when I first got it, it would cut out after getting warm. Figured out it was the ECM and replaced it.
First 2 days it rode great. Then it died as I turned around to head back to help someone that was stuck.
When I pull on the cord, it won't start most of the time. Then, it will for a few seconds.
Feathering the throttle doesn't help. It won't rev up and acts like it is bogging when you give it throttle.
If you let it idle it just dies after a few seconds.
Sometimes it backfires. I've now broken the pull cord on one of the back fires. (Think some rope is sticking out as I had just replaced it and left some extra so fixing that won't be difficult.)
Here are the things that changed from day 2 to day 3.
We noticed the clear cap on the gas cap had fallen off. So, there could be water in the fuel.
I just added Stabal to it before trying again and breaking the pull cord (which led me to look for help.)
We added about a gallon of high octane fuel. Ration is supposed to be 1-5. There were about 8 gallons in the tank and already had some high octane fuel. Maybe too much?
Elevation was the same each day and now I'm down at 400' and still doing the same thing.
Other thing I noticed was it seemed like the throttle cable was stretching a little. While trying to get it started, the end of the cable actually came out of the throttle body and had to put it back in. Don't know if it was way worse than before but did seem like there was more slack in the cable. I did have a new steering column put in it before the season but don't think that affected anything.
Thankfully we hadn't gone too far in the 15 min and the tow back to the trailer wasn't too hard.
I"m just at a loss of what it could be. I don't even know where to start trouble shooting.
Could the water in the gas actually make it backfire? How could the timing get off like that?
It is definitely getting spark. Seems to be getting some fuel. Could be the fuel filter but not sure why that would make it backfire. ??
Same with fuel pump. I could see where some gas would eventually feed in enough to get it to start but then not let it run but why would it backfire.
I tried to search the forums for a similar situation but either not there or I don't know the right terms to use.
Open to suggestions. Thanks in advance.
