Default Re: chain tension

the main reason for a tensioner shifting sideways is a slightly off center rear sprocket that has had the chain tension set when it is at it's loosest point rather than at its tightest point (when the chain gets tight, it pushes the tensioner down)

other problems here are a rear fork too small for the tensioner to grip (add a small piece of metal under the tensioner clamp), or sometimes the cheap bolts for the clamp are stretching (get better bolts)
