I went out on a Buell test ride once while I was in Kamloops. The O2 sensor failed and the bike choked out while I was rolling into a corner on the way up to Lac Le Jeune.
While driving back in the Buell truck with the bike in the back, we stopped to pick up a tail light cover that had fallen off of another one of the test bikes.
When they were unloading my test bike at the shop, I noticed a splinter of aluminum jammed up between the rear disk and pad. Apparently they had been working on the bike that morning and had screwed something up. Glad I didn't use the rear brake during the ride.
On separate, more recent ride, we went out on a warm day. It felt like I was sitting on a toaster oven.
