What would you all think is an un acceptible amount of air loss in a rear suspension? I have an 08' Ultra, and it seems to be loosing about 5lbs per month. (I have only noticed this in the last 6-8 weeks) I talked to the service guy at the local shop, and he says that's not uncommon, although some bikes go years and never loose any. At 5 lbs per month, he says they would never find the leak. The bike is under warranty til April of 10'. I'll keep a watchful eye on it, but I'd like to hear your thoughts.
