Re: My chain is saggy
Moving the tensioner bracket forward will decrease your chain tension. Moving it back will increase it. The tensioner wheel can be moved up in the slot. That will tighten the chain but possibly not enough. You still might be faced with shortening the chain.
In addition to master links there are also half links which might be a way for you to get the right tension.
Don't forget: 1/2 to 3/4" slack on the top run with the bike moved forward against a compression stroke of the engine, clutch engaged. More or less tension and you're asking for trouble.
