No, you should not attempt to start a motorcycle if there is water in the engine or fuel system. Water in the engine or fuel system can cause significant damage and potentially lead to expensive repairs. Here are a few reasons why starting a motorcycle with water in it is not advisable:
Hydrolock: Water is not compressible like air or fuel. If water enters the cylinders of the engine, it can cause hydrolock, which occurs when the pistons are unable to move due to the presence of a non-compressible liquid. Attempting to start the engine in this condition can cause severe damage to internal engine components, such as bent connecting rods or damaged crankshafts.
Electrical System Damage: Water can cause electrical shorts and damage to sensitive electrical components like the ignition system, spark plugs, and wiring. Attempting to start the motorcycle with water in the electrical system can lead to malfunctions and potential electrical failures.
Fuel Contamination: Water can contaminate the fuel supply, whether it enters the tank directly or condenses in the fuel system due to temperature changes. If water mixes with the fuel, it can disrupt the combustion process and cause misfires or engine stalling.
If you suspect that water has entered your motorcycle's engine or fuel system, it's best to avoid attempting to start it. Instead, have the motorcycle inspected by a qualified mechanic who can assess the extent of the water damage and perform any necessary repairs or maintenance. It's important to address water-related issues promptly to prevent further damage and ensure the safe operation of your motorcycle.
