MUFFLER REPACKING
P74
HOW-TO
STEP 6: Reassembly is a little
different for each stock or aftermarket
system but generally the reverse order
of the disassembly process. It is impor-
tant to use the proper amount of pack-
ing materials and follow the instructions
provided for each brand/model. The
packing kits come in various styles from
loose materials that are weighed to de-
termine the proper amount, to blankets
and "pillow" style.
One of the most critical steps is applying high temp
silicone at the junction between the bottom and/or end
caps. Skipping this step will result in an exhaust leak,
which hurts performance and can cause backfiring.
STEP 7: You will need to
apply high-temp silicone at the front/
end cap to avoid any exhaust leaks.
This is an extremely important step.
While most
mufflers will come
apart on one end,
the KTM EXC
mufflers
come apart
on both ends.
Water can damage muffler
packing so it is critically
important to use a plug when
you wash your bike.
All done and as good as new.
STEP 9: If your
system includes a spark
arrestor or sound reducing
insert, re-install that.
You are now ready to
reinstall your muffler and
enjoy a quieter, better per-
forming motorcycle. CN
STEP 8: Reinstall the screws or rivets to secure the front/end
cap. If your system uses rivets (such as Yoshimura systems), it is recom-
mended that you use the special rivets they have available as they are
different than the rivets that you will find at a typical hardware store.
