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. If you find a leak, a
little high temperature silicon sealant should fix it. After 50 to
100 miles, recheck all fasteners for tightness.
