I have definitely seen a similar bolt on my bike. I would agree with the above, or possibly a heat shield bolt (near the rear brake fluid reservoir). Could even be an upper exhaust hanger dependent on your exhaust. Like I said, I have seen something similar, and I have done slip on install, fender eliminator, and integrated tail light, so I would say somewhere in that region. good luck.Lower exhaust hanger, behind oil pan, just before the turn to come up. I think.
The bolt that held my front brake lever on is somewhere between turn 2 and 3 at jennings :retard: no front brakes into 3, that was fun, I got the lever back but not the bolt.It's probably just something you picked up on the track. I've found a razor blade and penny in my belly pan before.
