slight dive to the left

[HwyRider]

For the past couple of weeks each time that I stopped the bike it felt like it was taking a slight dive to the left hand side. I thought it was just me and shrugged it off. It did it again to me earlier today so I thought that I better get to the bottom of it. My left rear shock had zero air pressure and the right had 20 psi. Not sure what caused that but will have to keep an eye on it. After putting both shocks to 20 psi the bike now stops straight. Someone else may run in to this some day so I figured I would post it here.
