Is it normal for the Belt to travel across the rear sprocket?

[NorwegianRT]

Last time my belt was adjusted it was done by the dealer cause I also got a new belt.
If I am not remebering it all wrong from when I did it myself, you shall turn it clockwise.
However, it is easier to see and figure out if you have your Spyders rear wheel off the ground. Jack it up so tire is free off the ground. Also good to have two blocks infront of the front wheels incase it should fall off the jack.
Loosen the 36mm nuts that holds the bolt going through the wheel just enough so that you can adjust the sprockets.
Use 1/4 turns and see how the belt reacts to you adjusting.
When happy, tighten the 36mm nuts to the specs and you are good to go.
