जावा 42

I have a Jawa 42.1 which a monkey dropped once. After 4 days the radiator fan got stuck and the wiring went red. After going to the service center, they clamped it in the insurance whereas it should have been covered under warranty. The bike is in the service center for a week now neither the company is passing the warranty nor the insurance people are passing it. If the fan got jammed due to the fall, then how did the bike run for 4 days in this heat. Now they told me that it will cost 15,000. It is the company's fault. They do not want to give the warranty. Please, if someone is buying it, then don't take it. The maintenance is very high. Something or the other keeps going bad every 1-2 months.
