Why can't the motorcycle start after being exposed to rain?

Motorcycle fails to start after being exposed to rain due to the following reasons: Kill switch water ingress: Usually caused by water entering the kill switch. The electrical lock is generally unaffected. Ensure the ignition connector faces downward and inspect it. Solution: Moist air, rainwater, or humidity in the air may cause poor circuit performance and weak high-voltage electricity. Loosen the drain screw to check for water presence. Extend the carburetor vent tube and waste oil pipe opening to a drier area inside the frame, and cut the pipe opening into a long bevel shape. Precautions for riding in rain: Wrap the dashboard with transparent plastic to prevent water ingress. Some roads may have large puddles due to poor drainage or low-lying terrain. Assess water depth before crossing—it should be below the air intake and exhaust pipe height to prevent stalling. If the engine stalls and cannot restart, push the vehicle to a safe area to diagnose the issue. Do not attempt forced ignition if unable to resolve independently, as this may cause greater unnecessary damage.
