Does anybody else out there have a problem with the air shock on their Silvio? Most of the time by shock will lose pressure at the beginning of a ride, and the boot that covers it is flat, or almost flat, during normal riding on smooth roads. I have always had trouble getting the right amount of pressure into it, as a certain amount of pressure is lost while removing the pump (unscrewing it.) It seems to be only a very little bit of loss. I pump it to about 185 psi hoping to get 180 psi after removal of the pump hose. It seems fine when compress the shock while standing over the bike with the front break on, but after the first dip in the road while riding it looks almost flat. Any thoughts? I've had the bike a year now, and I have always had this problem, about 70% or more of the time.
