Cam plate question?

That tensioner was taken off of a motor that was built at Shadydell speed shop. "Ryan" . The motor didn't last but one good rev after Dyno runs. So that tensioner is junk I just used it for pictures. I have no clue why he did that but most of his motors were time bombs. LOL Good Eyes your the first one that noticed that and I have used that picture several times in the past.
