I recently installed a 13T sprocket. When I put it on the splines, I just slipped the chain over it and did not make sure that the slack was about the same on the top and bottom of the chain. I adjusted it by checking the amount of slack mid way on the lower part of the chain. After thinking about it, I am second guessing myself and wondering if I might have it to tight on the top. Do I need to go back and take it off and start over? Thanks.
