so I decided to get a new chain and sprockets for the shee and i went with a 43 rear for the trails. I have a f*cking problem. the chain is either to tight with the adjustment on the carrier all the way up or I ad another link and it is to slack with the carrier all the way back. I am needless to say, right f*ing livid!Has anyone ever had this setup, and if you have, what's the deal. How can I fix. I don't want the chain to fly off and destroy my case. please help.
