With my other Liquid cooled bikes, Valk and GL1000s, I have never felt the cooling fan come on. I may hear it or feel the heat pushing up, but never felt the fan come on. On the F6B I can actually feel a vibration while stopped and the fans come on. Is this just a matter of the dual side mounted fans closer to the rider vs me being used to a single fan out front?? I looked over the fan blades and see no broken or cracked blades. Wonder if this just the nature of the beast or should I be looking deeper into it.
