Why does the motorcycle fan keep running?
2 Answers
Motorcycle fan keeps running due to a malfunction in the cooling fan assembly or its wiring. Here are relevant explanations about motorcycles: 1. Working principle: When the pedal is pressed, the mechanism pressurizes the spring, causing its periphery to lift and separate the pressure plate from the friction plate. At this point, the friction plate and flywheel lose connection, meaning even if the engine continues running, power won't be transmitted to the transmission or wheels. This allows the rider to shift gears or stop without stalling the engine. 2. Power transmission: At low crankshaft speeds, the two friction plates don't contact the housing, preventing power transmission. At high crankshaft speeds, centrifugal force causes the friction plates to expand outward, contacting the housing and enabling power transmission.
As an experienced rider, I'm telling you, a motorcycle fan running continuously is no small matter. The most common cause is a faulty temperature sensor sending incorrect signals to the fan, making it run non-stop. Another possibility is issues with the cooling system, such as a clogged or dirty radiator, forcing the fan to work overtime to compensate for insufficient cooling. Wiring problems are also frequent, especially in bikes with modified electrical systems - stuck relay contacts or aged/short-circuited wiring can trigger this. I must warn you, a constantly running fan indicates potential engine overheating. Continuing to ride risks cylinder seizure. On my last long-distance trip when this happened, I immediately pulled over to let the engine cool while checking coolant levels. If you can't identify the cause, get it to a shop immediately. Don't repeat my friend's mistake of stubbornly riding home - he ended up with a warped head gasket and costly repairs.
