Removal
3. Install (No. 3)

tailpipe outlet. Using the
(No. 5)

aluminum spacer, align
muffler mount bracket to muffler mount and
secure using (No. 4)
M8X40H,
8mm bolt as
shown on the assembly diagram. Torque bolt to
23 Nm (2.3 kg-m, 17 ft-lb).

ST-200,
spring puller tool.
6. Install (No. 7)
RACE-SPS-1,
medium exhaust
spring between tailpipe and header using
ST-200,
spring puller tool.
7. Re-install right side panel following the opposite
steps of removal.
Note: Check to make sure the side panel is not
contacting the tailpipe. If necessary, trim
the bottom right corner of the side panel.
8. Before starting motorcycle, check for proper
clearance between new exhaust system and
rear suspension (i.e. tire, swingarm, brakes,
rear shock, 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.
9. 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.
Note: After starting motorcycle, it is normal for
new exhaust system and muffler to emit
smoke until oil residue burns off.
