I think you're joking. I wouldn't do that with my good belt. This belt was already ruined and I bent it as a photo was requested.

You can even see the pattern on the pulley, you need to look and see if you can figure what caused that.

Thanks for the heads up. When I get everything installed again I'll try to figure out what isn't lined up properly. As for now, I have a couple of weeks to wait for my front belt sprocket.

Not everyone knows that, so just a warning for others who may be so inclined to turn a belt inside out.

I'm curious if anyone has flipped a new belt and ran it until failure. Like a Harley Mythbusters episode.

For me it is the labor involved.

Chains get sprockets.

Belts get pulleys.

My FSM calls it a Belt Sprocket. Pully does make sense though.
