Brake Cleaner is NOT good on painted surfaces! I doubt that it does those o-rings any good either, but it would sure s*ck to get any on the fender paint or chain guard, tank, etc., and it may be just as bad on the finishes of the sprocket hub and wheel.

We use a lot of sprayed on brake cleaner in my shop - up under the cars - spraying off motor oil spillage and the like. Some of the oil filters screw on horizontally, so there is always some spillage on to the frame when changing the filter, and not cleaning it off is a guarantee the car is going to be back with a perceived "oil leak". Up under the cars though, it is hard to get it on anything it could hurt.
