I have a 17 Chieftain and have a question on the shock. Aired shock up to 75psi do to a passenger riding a long. Passenger canceled. Went for a 200 mile ride. Then bike sat in garage. I checked the air pressure in 6 days and the pressure was at 63 psi. Dealer said your going to loose a little pressure going over bumps and that sort of things. That does make sense I think. I also know that when checking pressure I'm going to loose 1-2 psi right? I did the water spray on valve with showing no leaks. The question is. Riding 200 miles and bike sitting for 6 days. Is loosing about 10 psi the normal?
