Oh boy, it is clear now that you should not own a bike, call me and I will get it off your hands. $25.00 sounds about right for value on a FJR with a broken oil pan. :yahoo:
As it was said, no biggie, but I'd attempt to reattach it with JB Weld after thoroughly cleaning both sides, and clean the excess before it dries; it should look like it never broke after the fix.
And if it falls down somewhere, at least you tried. Take care.
