Repacking the Muffler

• 1). Remove the muffler from the motorcycle, using a socket wrench to unscrew the muffler's mounting bolt. Loosen the muffler clamp with a Phillips screwdriver. Pull the muffler off the exhaust pipes.
  
  
• 2). Remove the rivets from the outlet end of the muffler, using an electric drill. Pull the outlet cap off of the muffler.
  
  
• 3). Pull out the muffler's core tube and its remaining fiberglass packing material. Unwrap the packing material and remove the core.
  
  
• 4). Wrap the core in a sheet of new packing material. Insert the wrapped core into the muffler.
  
  
• 5). Reattach the outlet cap to the muffler, using a rivet gun.
  
  
• 6). Reinstall the muffler onto the exhaust pipe.
  
  

Installing a Baffle

• 1). Measure the inner diameter of the muffler's outlet pipe, using a tape measure. Select a slip-in baffle that is small enough to fit snugly within the muffler's outlet.
  
  
• 2). Insert the baffle into the muffler's outlet pipe, using a rubber mallet if needed to tap the baffle into place.
  
  
• 3). Drill a small hole through the bottom of the muffler's outlet pipe and the baffle, using an electric drill.
  
  
• 4). Insert a metal screw through the holes to secure the baffle to the muffler. Tighten the screw with a Phillips screwdriver.
