mert, I wouldn't let it worry me a bit. There is those of us who strive to understand the inner working's of these machine's and know the difference between a 790 with a 270 degree crank as opposed to a 360 degree one. There are just as many who would rather not be worried with such trivial matter's. They just want to ride and let someone else worry with such matter's. There's good folks in both groups. I often ride with a friend who barely knows how to put gas in. He's a descent guy and great fun to ride with, he just isn't concerned with mechanical matters and comes to me for help when he's perplexed. When I run into circumstances such as your's I always find it easiest to just say, oh....
Nice bike, have a good ride, and continue on with mine.
