I've done 1100 kms on my extreme since the last servicing. Pickup is really good, thanks to the new clutch plates.
I'm still plagued by the milage issue. I had replaced the plug with Bosch UR5DC twin electrode, but could not observe any performance gain even after 1100 kms. Milage is still hovering around 38-40 kmpl.
So I decided to revert back to the recommended NGK CPR8EA9. Below is the image of Bosch plug after using for 1100 kms.
