Dude,,,,,, belts are for babys..
Real bikers run chain...............LOL (just kidding)
I have heard stories like this too many times. After an engine swap, I went to chain and have been happier ever since.
The first time a few of my friends broke belts doing burnouts, we laughed and they went to chains.
The best thing you can do is run a lower belt guard if your in love with belts.
