Engines don’t usually fail overnight - they give you warnings. If you hear knocking or ticking noises, feel slipping gears, or smell burning oil or fuel, it’s time for service. Poor throttle response, hard starts, or black smoke from the exhaust are also signs your fuel system or ignition needs attention.

Common red flags include:

- Difficulty shifting or slipping out of gear

- Excessive smoke or oil consumption

- Poor fuel mileage or loss of power

- Rough idle or stalling

- Fuel leaks, clogged injectors, or carb flooding

For dirt bikes and ATVs, hard riding and dirty environments can clog air filters, gum up carbs, and wear out clutches faster. Regular service prevents breakdowns on the trail or track.
