1. Bore damage: If the bore (cylinder) of your engine is damaged, it usually means the engine is struggling to maintain proper compression. This can lead to several symptoms:
Loss of power or difficulty accelerating.
Increased oil consumption, leading to lower oil levels.
Excessive smoke (usually white or blue), which is a common sign if oil is burning in the engine.
However, not all bore damage results in visible smoke, especially in the early stages. It's possible to have bore wear without obvious smoke if the damage isn’t severe enough to burn large amounts of oil yet.
2. Automatic acceleration: If your scooty is accelerating faster on its own, that could be due to several factors like:
A sticking throttle.
An issue with the carburetor or fuel system.
Air/fuel mixture problems caused by engine wear.
3. Low engine oil: Low oil levels can also cause the engine to run hotter and affect performance. It could contribute to accelerated wear on the bore, piston, and other internal components.
What to do:
Get a second opinion: If you're unsure about the diagnosis, it's a good idea to visit another mechanic. They can check the compression in the engine and confirm if the bore is really damaged.
Monitor for smoke: Keep an eye on the exhaust for any signs of smoke in the coming days. If it starts smoking, that’s a clearer sign of internal engine issues.
Engine oil: Make sure you’re maintaining the proper oil level, as low oil can cause further damage to the engine.
In summary, bore damage can happen without immediate signs of smoke, but if left unchecked, it may lead to that and other issues. It’s good to be cautious and get another mechanic’s advice if you're uncertain.
