I am having a problem with my chain. I recently purchased this go kart and installed a new jackshaft, sprocket, final drive, and new bearings. When trying to install the chain I can add a half link and the chain will fit but it's very loose and when I hit a bump or anything the chain will fall off, if I take the half link out the chain is too tight and I can't get the master link hooked up. I counted the large sprocket and it has 54 teeth, the small sprocket has 9 teeth. Any ideas on what I'm doing wrong or what I can change to get this to fit together correctly?
