Camber is how the tire leans in or out at the top. From your description and pics, it looks like you have negative camber, which is where the tops of the tires tip in towards the frame. As Cochise said, a little bit of negative camber is usually good for handling.
Toe in is when the front of the tires turn in towards the center of the bike, and toe out, of course is when the front of the tires are turned out away from the center. In a street car, you generally want a little bit of tow in as it makes the vehicle want to track straight without driver input. Toe out can actually aid turn-in during cornering, but makes the vehicle a little bit less stable on straights. The vehicle will tend to follow ruts and uneven surfaces more than a vehicle with some toe in.
Anyhow, there is a point where toe in or out, and camber, both negative and positive will negatively effect handling. I am just trying to determine if this mix of parts will create this type of situation, or if it can be tuned out, or is not an issue to begin with.
From the sounds of it, if the bike handles well with the suspension both unloaded and loaded, it should not be an issue. I do wonder about compression and bind, as Mr 305 brought up. Have you seen any issues during jumps that would indicate binding or bottoming on the spindles?
