How long can you hold a wheelie before the engine has enough!
He was mid wheelie when the engine let go! It shot fluid and internal parts all over the place! He almost had a huge wreck because of it, it was like a small explosion between his legs. That must feel crazy when it finally brakes and you lose all power! He might have been starving the engine of oil when he was up for that long. The bike is not designed to be tilted back like that!
