Why Can't the Motorcycle Throttle Twist?
2 Answers
Motorcycle throttle unable to twist may be caused by a lean air-fuel mixture or failure to warm up after starting, leading to insufficient fuel supply, or it could be an engine issue. First, check if the engine oil level is too high. For fuel-injected motorcycles, it is recommended to clean the throttle body. Relevant information about engine oil is as follows: Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption in the engine. It is often referred to as the 'blood' of the automobile. Composition: Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve the deficiencies of the base oil, imparting new characteristics, making them an essential part of the lubricant.
During my years of riding motorcycles, I've encountered several instances where the throttle wouldn't turn, feeling as if the grip was locked by something. The most common causes might be aging and rusting of the throttle cable or blockage by dust and mud. For example, not cleaning promptly after rain can allow moisture to invade, causing corrosion of metal parts and the cable getting stuck in the sleeve. I would first try to loosen the throttle sleeve and spray some lubricant to see if it helps; forcing it might damage internal components or even cause loss of vehicle control. Another possibility is foreign objects falling into the grip gap, which requires cleaning with a soft cloth. Remember, regularly checking the flexibility of the cable is crucial. I often pay extra attention during maintenance to ensure I can enjoy riding without worries and avoid having to find a repair shop midway through a trip.
