Nope but I rolled one down a hill folded bars onto tank cause they wasn't over tightened. Didn't bend stem two more guys and me pulled them back to normal and I finished my ride. I think last flip bent stem or upper hoop idk but it ain't right:haha:I'm a restoration mechanic bro. I tear down cars and rebuilt all the time. If you just tighten by hand bolds buy hand you will have leaks, vibrations, lose bolts, striped threads, lost bolts and ect. For like a air box or something not as importain I wont torque it but valve covers, sprockets, hubs, handlebars and steering stems, id rather take 2 more secs to torque it than having probs later. Have you ever been out in the desert, miles form your truck and your handlebars slide down? Thats a bitch!
