what's wrong with my 103 build?

Not sure why the belt has broken 2x in the last 5000 miles. Happens when bike has been sitting for awhile, and as soon as I put it into first. That's why i removed the 30 tooth, thinking is was so small and the angle so tight that it was stressing the belt. Could also be over tightened during installation, so i'm having the dealer take a look at the tension.

Attached is the dyno with the :29:AFR for your insights on why it's not performing like everyone else claims there's is!

I believe it's "RANGERS LEAD THE WAY"! Class 11-74

looks to rich to me .. dipping below 12:1 from about 3-5 k i think .. and i could be wrong that you would get better performance being around the dashed line about 13 to 13.2 :1
