The stock sprocket is much thinner than the length of the spline and have room to float to self center. The aftermarket sprockets have a wider shoulder that spread the load out over the splines better to prevent the wear and centers the chain properly. I can get a picture of the difference Sunday.
Thank you Kenny; I would like to see that picture.
FYI: I adjusted the chain to the factory recommended tension (1 3/8 to 1 3/4) and it is too tight! I verified this by compressing the rear suspension until there was a straight line through the centerline of the drive shaft, the swing arm pivot, and the rear axle. At 1 3/4 inches of slack, with the suspension compressed, there is no free play. I thought this was why the splines were stripped off the drive shaft where the sprocket mounts when I got the bike.
