Anyone know about ATV engines?

Hi all,

Soo I bought a Can-AM ATV (I knew I should have stuck with Honda) about 2 years ago, maybe three, it was new. I think it's a 2017 Outlander 480 or whatever. Anyway since I got it it has nearly stalled or stalled when I first push in the throttle or when I am just about to let it go. I did tell the dealer and of course they couldn't find anything wrong. The problem has only gotten worse and now it is stalling more than it is nearly stalling, and I have no idea what it could be. I have like no knowledge, or interest in engine stuff or working on it myself, but at least if I had an idea what might be causing it I could bring it to a repair shop to see if they can fix it.

Any ideas? I have tried higher octane gas and lower, and the in-between kind to no avail!


Thanks,

T

 

Is it efi or carbed?

 

I don’t know much about them either, but I bought a 2015 Polaris 570 last fall that had 9 hours on it. It did the same thing you are talking about and I had to have the fuel
Pump replaced, no issues since then.

 

If it has a carburetor it could be gummed up with bad/old gas.

 

Need to know if fuel injection or carb. Knowing that aside, did you treat the gas with something for the ethanol? If you leave pump gas in a ATV, bike, outboard for anything over a month it starts to absorb water. That could be a factor. Fuel injected engines handle that better but it can still be a problem.

#1 issue with any motorbike, ATV, etc is bad gas. I sell boats and ATVs for a living and we have a full service shop that works on them all.

Other suggestion - could be the fuel pump going out.

Have you kept up on the maintenance? Oil and filter changes? It probably has a fuel filter, could be clogging. 3 years old, may also be time for spark plugs.
