ATV Riding Emergencies - How To Be Prepared

Engine oil should be clean and up to the full line. For slogging and rock crawling, you'll want 20W50 oil, even in colder weather.

All nuts and bolts need to be in place and tight. Secure any loose mudflaps or plastic trim, and make sure cargo racks are tight. You don't want any parts flopping around on the trail, and you might have to use the racks for lifting or towing a machine. Skid plates are prone to losing their attachment bolts, so take the time to get underneath your machine and check for any loose or missing fasteners.

The air filter should be clean and in good condition. A new filter is cheap insurance against engine damage due to dust. If you're going on a multiday ride in dusty conditions, bring along a spare filter in a plastic baggie, oiled and ready to install.

Drum brakes should be adjusted until tight, then backed off two turns to allow for heating and expansion on long downhills. Brake fluid should be at the full line and clean, not milky or black.

Check radiator, coolant and hoses for leaks. If your machine has a cooling fan, let the engine idle until the fan comes on to check its operation.

Driveshaft boots should be in good condition. They're the only thing between the CV joints and the water and dust of the trail.
