6. Separate old packing from core and disguard
packing.

7. Cut new packing to mufer length.

15. Before you run the bike, clean off all ngerprints 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 rst 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.
