    Does this look right?

    Was the Slingshot moved in reverse just before the pic was taken? If so, try going forward several yards and check again. The belt will position differently after forward rotations vs reverse rotations.

    The left pic looks like something is mis- aligned. The right pic looks ok.

    Looks good to me, rear is perfect, front looks OK. You have to look at the very top of the front sprocket to read the real path of the belt.

    Thanks folks, the belt around the angle drive just looked like it was running to the inside maybe more than it should......................

    Under pressure it walks to the middle.

    • I aligned my belt so that with a bright light you could just see a tiny space between the tooth of the belt and the bottom of the tooth of the sprocket. Not the top of the belt and the top of the sprocket but looking down inside the tooth of the sprocket. Backed out of the garage and pulled around the driveway (circle driveway) and the belt was off center to the right. I thought uh oh, great something's not right. I took it for a ride anyway and ran some errands. Every time I stopped I looked at th belt, sometimes it was left of center sometimes it was right of center but never as close to the side of the pulley as before. So I guess it's ok where it is.
    I also changed the angle drive oil to royal purple 75w140 and put in a full quart. Changed the belt tension to just over an inch cold.

    So besides the belt alignment issue I was also listening and looking for angle drive noises and checking belt tension. So for the first couple blocks out of the neighborhood I could hear a hint of minor belt squeak that I never heard before only at very low speeds when starting from a dead stop. As the belt warmed up that little squeak went away. I'll have to test it again cold to see if the squeak comes back. As far as angle drive noise goes, it's definitely quieter after the changes. I get a little whirring on acceleration and deceleration only, at cruise it is very quiet. Since I changed multiple things at the same time, (tension, drive oil, alignment, and greased the u joint) I can't say for sure which one had the biggest effect on the noise I was getting.

    My sling is a 2016.5 with just over 2000 miles on it.
