Why Is My 2025 Can-Am Canyon Getting Bad Gas Mileage?

Why Your 2025 Can-Am Canyon Is Using More Fuel Than It Should

Nothing about a 2025 Can-Am Canyon suggests it should be thirsty. It is a fuel-injected, liquid-cooled four-stroke with a belt final drive, so the carburetor-era suspects — a choke left partly on, gummed jets, a misadjusted float — are not part of the conversation. What remains is a short list of realistic explanations: the conditions you ride in, a few maintenance items that slip, sensor inputs that push the injection into a rich state, and mechanical wear.

First, Make Sure the Problem Is Really There

Start by confirming the change is real. Fill the tank to the same level each time, reset the trip meter or note the odometer, ride normally, then refill at the same station and divide the distance covered by the fuel you added. A single tank proves nothing — weather and traffic swing the result badly — but three or four consistent tanks give you a trend worth trusting.

Riders who never do the math notice the same problem differently: the fuel level drops faster on a familiar route, or fuel stops arrive more often. One measurement trap is worth ruling out early. A change in rear tire size or profile alters how far the wheel actually travels per revolution, which skews the odometer and makes the Canyon look thirstier than it is. Belt final drive rules out sprocket gearing as a variable, but tire circumference still counts.

Conditions and Habits That Quietly Raise Fuel Use

Cold weather is a major innocent cause. The engine runs rich until it reaches operating temperature, and dense cold air requires extra fuel to hit the correct ratio; winter-blend and ethanol-blended fuels also carry slightly less energy, so more of them is needed for the same distance. Long warm-up idling burns fuel while covering no ground at all.

Wind and load matter just as much. Headwinds, sustained highway cruising, a passenger, and loaded luggage all add work, and the Canyon’s upright seating position and broad frontal area mean speed costs it more than it would cost a tucked-in sportbike.

Short hops and an eager right hand finish the job. Hard acceleration between stops, late braking, and trips too brief to warm the engine all push consumption upward. If the change lines up with a new route, a colder season, or a heavier throttle, you may have your answer without touching a tool.

Rolling Resistance: Tires, Brakes, and the Belt

Tire pressure tops the free-checks list. Underinflated tires flex more, converting fuel into heat instead of forward motion, and they hide the effect well. Check pressures cold, before a ride, since a warm tire reads higher than it truly is.

A brake caliper that does not fully release drags continuously and is easy to overlook. After a ride that involved little braking, feel each wheel for abnormal heat and compare how freely they spin.

The belt final drive deserves attention too. An over-tightened belt adds drivetrain drag, and a belt running out of alignment can scrub against its pulley flange, quietly costing both power and fuel without any obvious symptom from the saddle.

Airflow and Ignition: Small Faults, Bigger Bills

A clogged or heavily soiled air filter restricts incoming air. The fuel injection meters fuel against measured airflow, so a restricted engine has to work harder for the same road speed, and that penalty accumulates over a whole tank.

Spark plugs are the other inexpensive item worth pulling. Plugs that are worn, fouled, or incorrectly gapped do not ignite the mixture cleanly, which wastes fuel and softens throttle response. This engine uses electronic ignition rather than contact points, so there is no points gap or timing drift to chase, but a weak coil or a damaged plug cap creates the same incomplete burn. The plugs are also diagnostic: dark, sooty deposits point toward an over-rich mixture rather than a change in how you ride.

Fuel Injection Sensors and Delivery Faults

Fuel injection depends on sensor feedback to hold the correct mixture. An oxygen sensor that has aged or failed can bias the system rich, particularly once the engine is running in closed loop, producing a quiet rise in fuel use with no obvious drivability complaint.

Coolant temperature is the other critical input. A sensor reporting the engine as colder than it actually is keeps the system adding fuel for a warm-up that never ends, and a wiring or connector fault at that sensor produces the same rich-running behavior.

On the delivery side, an injector that is dirty or seeping fails to atomize fuel properly and can dribble between pulses. External leaks — a weeping fitting, a cracked line, a loose clamp — cost fuel outright. Having stored fault codes read is worthwhile even when nothing feels wrong, and a warning message on the display should not be dismissed as unrelated to the mileage change.

Engine Condition, Cooling, and Modifications

Mechanical wear is the explanation nobody wants, but it belongs on the list. Low compression from worn rings, poor valve sealing, or simply high mileage reduces how efficiently the engine turns fuel into motion, and it often appears first as worse fuel economy rather than a dramatic running fault.

Cooling matters because the Canyon is liquid-cooled. A thermostat stuck open prevents the engine from reaching full operating temperature, and an engine that never warms fully runs richer than one held at normal temperature.

Modifications can also be the cause. An aftermarket exhaust or high-flow air filter fitted without matching calibration changes how the engine breathes, and without that adjustment the fueling can end up richer than intended — louder, sometimes flatter, and thirstier.

When to Hand the Canyon to a Mechanic

Some symptoms point past routine maintenance. A strong raw fuel smell, black smoke from the exhaust, heavily sooted spark plugs, or a warning message on the display all suggest an over-rich condition that a visual inspection alone will not explain. Rough running, a misfire, or a noticeable loss of power alongside the mileage drop also warrants professional attention rather than continued guessing.

So does a drop that survives your basic checks — pressures set, filter clean, plugs fresh, nothing else changed. When you hand the Canyon over, describe the symptom plainly: how many tanks you tracked, how much the numbers moved, when it started, and what else changed at the same time. That gives a technician a real place to start looking instead of a vague complaint about fuel economy.
