Full synthetic oils should always look clean. They do not break down dirt and deposits like conventional oil. Instead they carry dirt leaving it in the filter (I know convectional oils will do that also). Many will have detergents to remove deposits.
Synthetics are great for new and low milage engines and if you only use them they will keep your engine/transmission clean for the life of your bike. But you still need to change it even if it looks clean you really cant tell by looking at it if the oil is breaking down.
