What can be put inside to damage a motorcycle engine?

Putting white sugar, gasoline, or small steel balls inside can damage a motorcycle engine. White sugar: When white sugar mixes with engine oil, it thickens the oil, clogging the oil filter screen and oil passages. This prevents the oil from lubricating various parts of the engine, leading to severe wear or even complete engine failure due to lack of lubrication. Gasoline: Gasoline reduces the viscosity (lubricating properties) of engine oil, making it thin like water. This causes severe wear on cylinder rings, and such damage is often undetectable during repairs. Small steel balls: Just a few small steel balls placed in a motorcycle engine can damage the internal gears once the engine starts running, ultimately leading to engine failure.
As a seasoned motorcyclist with over a decade of experience, I can share some personal experiences: Once, I accidentally filled the tank with gasoline containing a high percentage of ethanol, only to later learn that such fuel can easily corrode internal metal components, leading to clogged fuel injectors and engine overheating. Another time, a friend got water into the cylinder while cleaning, causing hydro-lock and nearly stalling the engine. Small contaminants like dirt or sand, if they seep into the oil system, can accelerate wear on moving parts. Now, I strictly use only the manufacturer-recommended specialized oils and fuel additives, checking the air filter and oil filter every few thousand kilometers to prevent any foreign objects from entering. The internal space of a motorcycle is precise, and using the wrong substances can lead to costly repairs—ranging from a few hundred dollars for part replacements to the complete scrapping of the engine. I also make sure to cover it properly when stored to keep rain or dust out.
