U talking about the cam chain tensioner cover on the back of the jug? Look again... there are 3 bolts...one on top and two on botttom.  The one on the bottom right (sitting on bike) is hard to see if you are doing the job with motor in bike.   And, yes, removing it will give you the slack you need. 

Hope this helps.  Just tore my top end down for the first time also.  Take ur time, don't work mad or u'll break a fin like I did...haha
