REPLACING EXHAUST SILENCER PACKING MATERIAL
The competition silencer is completely filled with sound absorbing material
(fiberglass) to limit the motorcycle exhaust noise to within competition
limits. Fiberglass tends to burn due to the high temperature reached by the
exhaust fumes. This reduces both the noise absorption effect and the power.
To replace the fiberglass, take the silencer off the motorcycle, removing the
rivets (1) that secure the front cap (2) to the external pipe (3), remove the
cap. Remove the sound absorbing material to be replaced.
Insert TM’s fiberglass cartridge (4) in the external hose.
Re-fit the front cap (2) and secure it with the new rivets.
Mount the silencer on the bike again.
Grease the ends of the pipes to make fitting the silencer easier.
DANGER
- CAUTION: DANGER OF BURNS!
- THE EXHAUST SYSTEM GETS VERY HOT WITH THE MOTORCYCLE
RUNNING. TO AVOID BURNS, ALLOW THE SYSTEM TO COOL
BEFORE STARTING WORK ON IT.
- IN CASE OF BURNS, IMMEDIATELY PLACE BURNT AREAS UNDER
COLD RUNNING WATER AND SEEK MEDICAL ADVICE.
WARNING
- Replace the fiberglass with new product purchased from TM dealers
or, if that is not possible, with an equivalent product.
- Never use flammable material to pack the silencer.
