How to Recover Your Adventure Motorcycle After a Water Crossing Fail

1. Get the Bike Out of the Water

The first priority is getting the bike out of the water as quickly as possible. Water entering the engine, airbox, and electrical system can cause severe damage.

• Turn off the engine immediately if it’s still running to prevent hydro lock.

• Push or drag the bike to dry ground with help if needed.

• Put the bike upright on solid ground to start the recovery process.

2. Assess the Situation

Before tearing into the bike, check for obvious damage.

• How deep was the bike submerged?

• How long was it underwater?

• Did it fall on its side or stay upright?

• Did you try to restart it while submerged?

If the bike was only briefly in shallow water, you might get away with drying it out. If it was fully submerged, you’ll need to go through the full recovery steps.

3. Drain Water from the Exhaust & Airbox

A flooded airbox and exhaust can prevent the bike from restarting.

• Remove the air filter and check for water. If wet, squeeze out excess water and let it dry.

• Tilt the bike to drain water from the airbox and exhaust (lifting the front wheel can help).

• Remove the spark plug(s) to check for water inside the cylinder.

4. Check & Drain the Engine

If water got into the engine, you must remove it before starting the bike.

• Crank the engine with the spark plug out to push out any water.

• If necessary, drain and replace the oil—milky oil means water contamination.

• Check the fuel system—if the tank was submerged, drain and replace the fuel if needed.

5. Dry Out the Electrical System

Water and mud can cause electrical shorts.

• Disconnect the battery and dry the terminals.

• Check all connectors and wiring for moisture and corrosion.

• Use WD-40 or contact cleaner on electrical connections to prevent damage.

6. Restart & Test the Bike

Once everything is dry and drained:

• Reinstall the spark plug and air filter.

• Try starting the bike—if it cranks but won’t start, check for fuel or spark issues.

• Let it run and warm up to evaporate any remaining moisture.

7. Post-Ride Maintenance

Even if the bike runs fine, do a full check-up after getting home:

• Change the oil and filter again after a short ride.

• Check wheel bearings and suspension components for water entry.

• Inspect electrical components for corrosion over time.
