We get this question a lot here at HMF. Typically, the average rider will need to repack their exhaust after about 40-50 hours of riding. This can vary however depending on the type of riding. More aggressive race machines are going to need to repack more often than the average trail rider.
Repacking your exhaust requires an air rivet gun or an automotive style riveter. A small hand riveter will not work for this.
If you would like us to repack your exhaust system, see our Repair Services for details.
Step 1: Using a marker, draw a line representing the clock position of the inlet and exhaust.
Step 2: On the inlet side only, tap all the rivets until the stem drops.
Step 3: On the inlet side only, drill out each rivet.
Step 4: Using a rubber mallet, tap the exhaust shell to remove the inlet.
Step 5: Using a 4mm allen key, loosen the allen screws on the end cap.
Step 6: With the exhaust shell removed, discard of the old packing and wrap the new packing around the core.
Step 7: When wrapping the packing around the core, make sure to make it as snug as possible.
Step 8: Tuck the packing underneath the inlet.
