Maintaining the chain and sprocket in Vietnam

What happens if you don’t look after the chain and sprocket on the motorbike

The chain and sprocket set need regular lubing. This helps with the driving performance of the motorbike and extends the life of the set.
If you do not regularly lube the chain, the motorbike will begin to feel rough, driving is less smooth and the chain set makes loud grinding noises.
With time, the set begins to stretch (not really, but specifics later), which eventually leads to the chain falling off the sprocket.
As the chain becomes loose it creates slack, this causes the motorbike to be jumpy and perform badly.
