Does anyone have any pictures or instructions on removing the stock muffler/  I looked at my Clymer manual and the heat shield only shows one bolt holding it on but I still can't get it off.  Does anyone have any instructions or picture showing what needs to be done?

Thanks

As usually JOG is correct.  You should take the entire pipe and muffler off together.  There are 2 bolts on header ( 10 or 12 mm, can't remember).  On the forward control there are 2 bolts (15 and 17 mm).  On the muffler support near the rear axle their are 2 more bolts (10 or 12 mm) then it all comes off.  Their are a couple other items that you will loosen up to take the muffler from the pipe.  Taking it off is a lot easier than putting it back on.  On the rear muffler support it will be very helpful to get OEM rubber spacers (not sure if that is the correct term).  When you put it back together it will help keep that heavy pipe from vibrating the nuts loose.  Their not expensive; but, they are rubber and only go one once for the most part.  That muffler gets hot and bakes the rubber spacers to the muffler.  Best regards.  

The ones in the engine? They normally loosen right up. When I pulled my muffler, I didn't pull them, just loosened them and the nuts on the muffler, loosened the peg bracket bolts. You'll get enough wiggle room to remove the muffler.
