i turn the sprocket around and make sure it's true as i could.
the tensioner seems to be working good now a little loud but good,i had add a piece to the tensioner bar to keep the tensioner wheel for moveing down
i was out on it for passed 2days on off and i travel a nice ways to day and it diden come off or seem like it was going to.
but im still a little bit afraid it may happen again
i add some more pic of what i did
