They all are, mine is too, as long as the axle is aligned properly, it is normal.

 

Seems I misunderstood your post, thought you were concerned about the wheel not centered in the swingarm or in alignment with the front wheel. The Muds Tool is for axle alignment in the swingarm only as it measures the axle centerline from the swingarm pivot point. It is still possible to get the wheel off center by using incorrect spacers on the axle or placing the spacers back in the wrong location. After you get the wheel and spacer assembled correctly the wheel can still be out of alignment with the rubber mount system in the frame. A good manual outlining vehicle alignment will describe the process suggested in my previous post.

 

Nope, you had it right. My bike is dog-legged to the right, as I go down the road. Measuring the wheel, between the rails of the swingarm, tells me that there is almost a half an inch difference between the sides. If my method is accurate, than the wheel is crooked in the swingarm, and my imitation Mutt Tool confirms that.
