What are the consequences of adding diesel to a motorcycle?

The consequences of adding diesel to a motorcycle are as follows: 1. Difficulty in starting and damage to the spark plug. 2. Diesel is difficult to burn in the fuel tank, which can easily cause cylinder explosion. 3. If a small amount of gasoline is mixed with diesel, it will emit thick blue smoke, and the motorcycle will stall and fail to start. Below is some relevant information about motorcycles: 1. Motorcycles are powered by gasoline engines and are two-wheeled or three-wheeled vehicles steered by handlebars, known for their lightness, flexibility, and speed, widely used for patrol, passenger and cargo transport, etc. 2. Motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, touring bikes, etc.
I've seen motorcycles accidentally filled with diesel at repair shops several times, and the consequences are quite severe. Diesel is much more viscous than gasoline, and motorcycle engines are designed for spark ignition, while diesel requires compression ignition. Once diesel is added, the engine simply won't start because the compression ratio can't reach diesel's auto-ignition point. If it somehow starts, you'll hear severe engine knocking, black smoke pouring from the exhaust, and the bike shaking as if it's falling apart. Worse, diesel can clog the fuel filter, corrode the fuel injectors, and even damage the entire fuel supply system. I remember one customer spent nearly a thousand dollars just to clean the fuel tank and lines. If driven long-term, the engine will be completely ruined, and replacing it would cost even more. So, always check the color of the fuel nozzle before refueling—diesel usually has a green label—don't be careless.
My buddy made this mistake once when he rode his little motorcycle to the gas station and absentmindedly filled it with diesel. The result was the engine wouldn't start at all, and he had to push it for a long time before it finally woke up. Diesel isn't suitable for motorcycles because the engine structure is different—diesel burns slower, leading to carbon buildup in the cylinders, which can cause piston rings to seize or cylinder wear. After we forced it to start, it only ran for two kilometers before breaking down. We had to tow it to the repair shop, where the mechanic said we had to drain all the diesel and flush the fuel tank and lines with a special cleaner. The whole process cost around 500-600 yuan and wasted a whole day. Since then, I've always reminded myself to double-check the labels and not be lazy. Motorcycles use gasoline for lightness and efficiency—adding diesel is just asking for trouble, and the repair costs are heartbreaking.
