Fitment check and Notes.
a) Before starting motorcycle, check for proper clearance between new exhaust system and
rear suspension (i.e. tire, swing-arm, brake, rear shock, engine, and etc.) If any problem is
found, please carefully follow through the installation steps again. If problem still persists,
please call Yoshimura Tech Department at (800) 634-9166 / in CA (909) 628-4722.
b) It is recommended that the muffler and tailpipe be wiped down with rubbing alcohol to
remove oil and fingerprints. This will help prevent tarnishing of the finish after the exhaust
is heated up.
c) NOTE: After starting motorcycle, it is normal for new exhaust system and muffler to emit
smoke until oil residue burns off.
