Hello Yamaha lovers, I would like to know what is your preference when it comes to lubricating Yamaha? Please also mention your city as this is also a factor to be considered. I am using YamaLube for past 4 months and now i am making up my mind to change to ZIC M5 20W-40 because I feel like my bike gets warm then usual when travelling for 15 kilometers of heavy traffic of Karachi.
