1. Make sure the bike is completely cool before starting
the installation. Make sure the bike is secure on a
centerstand or ideally a service lift and remove the
muffler assembly form the bike.
2. Keep the S-bend tube attached to the muffler for
ease of removal when separating the inlet from the
outer sleeve.
3. Remove the 6 retaining screws holding the inlet to
the outer sleeve. Carbon and Titanium mufflers
have a stiffening band under the retaining bolts that
will be removed also.
4. Pull the S-bend away while holding the outer sleeve
to separate them.
5. Remove contents from inside the muffler core/
packing.
6. Separate old packing from core and disguard
packing.
7. Cut new packing to muffler length.
8. Roll new packing tightly over the wire mesh covered
perferated core and secure with tape on the packing.
9. Insert the new packed core into the muffler.
10. Replace the O-ring on the inlet if necessary.
11. Make sure the core goes into the core retainer on the
outlet and inlet as you slide them together.
12. Install the 6 bolts to secure the outer sleeve with the
inlet.
13. Torque the retaining bolts to 72in. lbs.
14. Re-install muffler to the motorcycle.
15. Before you run the bike, clean off all fingerprints and
dirt, as any oily residue will etch the metal and become
somewhat permanent when the system gets hot. Run
the bike and enjoy. It is normal for some white smoke
to appear the first time you start the bike. This is
packing/manufacturing oil from inside the pipe burning
off. Check for gaps or leaks. After 1 to 2 hours of riding
recheck all fasteners for tightness.
