I'm in the process of trying to get hold of all the people I sold my motorbikes to, so I can reinforce the tensioner. The last three got 3/16" stainless pop rivets like the Giant in the photo. I'm going to try and not use the tensioner at all on my next bikes, but if I have to, I will span the frame with a custom mount eliminating the possibility of twisting. A stretched chain and or worn sprocket is just begging to jump teeth and bind. As we strive to mount our engines, sprockets and tensioners more solid, it's obvious that if/when there's a problem, the tensioner is the most likely weak link.
