I have noticed an issue since yesterday, randomly the fan is not turning on and the bike overheats at slow traffic or behind a red light. Sometime it kicks in sometimes not. I don't know if it makes sense or not, the only change since yesterday is that simply changed the spark plug to NGK 5869. The engine runs much better now and less jerky throttle. I appreciate if some would shed a light. I suspect a loose fan cable connection or faulty relay? Thanks
