Soon after the bike is started up, a burning smell starts coming from somewhere in the engine area. No smoke. It is not a smell of a burned wires, plastic, or rubber, but a distinctive smell of an engine or exhaust as though the engine had been severely overheated. It's similar to the smell of a dirt bike after a race.
What can be the cause of that? What steps should I take to identify the cause and fix the problem?
