LoL! Hawg!!! Like anything else in life if you try too hard it never fails that it won't happen. In a relaxed unexpected situation with a lube pill in it's proper place the rear will open up with multiple explostions and there you have it a chainfire from the rear. Purely accidental can't be reproduced...otherwise we'd have a cure...the bandaid is be careful and pay attention. And it can still happen.
Good One Hawg...HeeHee!
