This is just a heads up thing for your bike .... After riding my bike and crashing a couple times as usual, I noticed the swing arm had a bad rub mark directly behind the master cylinder... Apparently, one of the crashes bent the master cylinder over enough that the hard plastic protective covering on the cylinder (not the master cylinder) was rubbing the swing arm as it would swing up and past the master cylinder ... this actually cut a pretty big gouge in the arm... I had no idea that this covering was hard enough to cut into the swing arm so be sure to keep a watch out for this one if you fall on the right side ...
