What are the symptoms of a motorcycle running out of oil?

When a motorcycle runs out of engine oil, the following phenomena will occur: Severe wear of parts due to lack of lubrication will happen in a very short time, until the engine cylinder, piston, rings, and crankshaft etc. seize up and stop functioning. Below is relevant information: Main characteristics of engine oil: (1) The engine is the heart of a car. Inside the engine, there are many metal surfaces that rub against each other during movement. These components operate at high speeds, in harsh environments, with working temperatures reaching 400°C to 600°C. (2) The new PurePlus technology can convert natural gas into crystal-clean full synthetic base oil. On this basis, exclusive dynamic cleaning technology is added to create lubricants with superior cleaning and protective performance. Under such severe operating conditions, only qualified lubricating oil can reduce the wear of engine parts and extend their service life.
The most common symptom of a motorcycle running out of fuel is the engine suddenly stalling, as if someone choked its throat. Last time I encountered this situation halfway up the mountain—initially, the power noticeably weakened, and even twisting the throttle to the max couldn't increase the speed. Then, the exhaust pipe made a 'puttering' coughing sound, the bike started jerking forward intermittently, and finally, it completely died. At this point, turning the key to restart would only result in the engine 'clicking' without firing, and the fuel gauge needle on the dashboard had long since hit the bottom. I recommend everyone develop the habit of checking fuel levels. If the fuel tank switch has a reserve setting, remember to switch it in advance. Pushing the bike to find a gas station is not a pleasant experience, especially in summer when you end up drenched in sweat and the helmet visor fogs up.
After riding motorcycles for eight years, I've noticed several clear signs when the fuel tank is nearly empty: First, the engine sound becomes hollow, as if it's starving and lacking power; then, the throttle response turns sluggish, unable to pick up speed even when revved to 7000 RPM; the most obvious sign is intermittent backfiring from the exhaust pipe, with 'pop' sounds resembling hiccups. Once, I didn't notice the fuel level while riding at night, and the bike suddenly stalled in a tunnel, almost causing a rear-end collision. It's advisable to check the fuel gauge every time you start the engine cold—refuel immediately when the needle drops below a quarter, especially for older bikes, as a stuck fuel float can display false readings. Carrying a foldable fuel canister can be a lifesaver in emergencies.
