Calm down! Take a deep breath before dismantling the entire machine. Many Kymcos use the oil light as a simple reminder to change the oil. Depending on the model, it goes on every 2,000km (typical) and stays on until you you turn it off with the hidden toggle when you've done the oil change. NOTE! This isn't in the Owners Manual, it's a hidden item that the dealer can charge you for when he changes your oil. The toggle is in a different place from one Kymco model to the next.
