I think I previously asked about this on the Crosstourer site, but in any case, I didn't get any good answer. When parked and switched off, my bike makes the strangest noise that is probably some kind of venting. It seems to do this relatively more often in the few hours after being shut off, but it can do it at any time. It sounds kind of like the lower pitch part of a donkey braying. It is pretty annoying. Can anyone relate and tell me what causes it and if it can be silenced?
