Over the years getting the rear belt to stay aligned in the center of the rear pulley has not been easy.

After you've gone through all of the tweaking to keep the belt centered, how does the rear wheel actually align down the center of the M3W relative to being "square" with the front end?

Based on others here and how they ended up having to remove the outside belt sprocket guide and let the belt hang off the sprocket a quarter inch or just a bit less, my guess is that you're going to be dog tracking going down the road.

What did this do to your front belt placement on the BB sprocket? Did the belt move and is now on a slight angle and not truly flat on the sprocket?

Maybe the MMC has changed the rear swingarm a bit and spacered out the rear sprocket to allow for a perfectly centered belt, hope that's the case.

Just throwing this all out there as over the years what you did on belt alignment has not been possible. Glad to see another biker on the forum. Welcome!
