2016 Polaris Ranger 900 XP Runs Lean?

Question

Hey there, I hope you’re doing well. I own a Polaris Ranger 900 XP, and I’ve started noticing some performance issues that have me concerned. Now, I’m not a mechanic, but I’ve been reading up a bit and I’m starting to suspect that it might be running lean. I’d really appreciate your expertise – could you guide me on how to determine if my intuition is right?

    Of course! When your vehicle is running lean, it means that the air-fuel mixture in the engine has more air and less fuel than it should. This can lead to a few symptoms. Are you experiencing any of these: hard starts or no starts, bogs, backfires, popping through the intake or exhaust, hesitation, detonation, low power, spark plug erosion, engine running hot, surging, high idle, or erratic idle speed?

    Well, it has been hesitating a bit during acceleration and I’ve noticed some popping sounds from the exhaust. So, yeah, some of those symptoms sound familiar.

    Got it. It does sound like you might be dealing with a lean mixture issue. There are several possible causes for this. It could be due to no fuel in the tank, a restricted or improperly routed tank vent, restricted fuel lines or fuel injectors, a plugged fuel filter, an inoperative fuel pump, or even an air leak in the system. This could include intake air leaks like issues with intake boots, intake adaptors, or the airbox cover.

    Based on the symptoms you’ve described, I would suggest checking the fuel filter and the fuel lines first to make sure they’re not blocked or restricted. Also, inspect the intake components for any signs of leaks. To help you with that, I recommend getting a can of carburetor and intake cleaner CRC Throttle Body & Air Intake Cleaner, which can be really helpful in cleaning up the intake system.
