Before you run the bike, clean off all fingerprints and dirt, 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 burning off. Check for gaps or leaks. If you find a leak, use a little high-temperature silicon sealant. after 50-100 miles recheck all fasteners.
Care & Cleaning
Keep the system free of dirt and moisture. Store in a cool, dry place. Make
sure the vehicle is completely cool before maintenance.
Stainless Header System: Polished stainless steel pipes will turn a light
golden hue after a few heat cycles, this is a normal characteristic of high-
quality stainless steel. Clean using a mild water-based spray cleaner. Always
apply cleaner or polish with a soft, clean cloth.
Titanium Header System: Polished titanium pipes will experience color shifts
ranging from deep blue/purple through amber after a few heat cycles. This is a
normal characteristic of high quality titanium. Clean using a mild water-based
spray cleaner. Always apply cleaner or polish with a soft, clean cloth.
Polished Aluminum Canisters: Use an aluminum or mag wheel polish to restore
the bright finish to factory spec. Brushed Aluminum Canisters: Clean using a
mild water-based spray cleaner. Always apply cleaner or polish with a soft,
clean cloth.
Carbon Fiber Canisters: Clean using a mild water-based spray cleaner. Always
apply cleaner or polish with a soft, clean cloth. Always make sure the
fiberglass packing inside is in good condition and not burned out, as exhaust
heat inside an empty canister will deteriorate the carbon fiber sleeve.
TBR sells repack kits (Road – #005-10038, Offroad – #005-10038MX) that include
everything you need to easily do it yourself.
Titanium Mufflers: For cleaning use a mild water-based spray cleaner. Always
apply cleaner or polish with a soft, clean cloth. Always make sure the
fiberglass packing inside is in good condition and not burned out, as exhaust
heat inside an empty canister will deteriorate the carbon fiber sleeve.
TBR sells repack kits (Road – #005-10038, Offroad – #005-10038MX) that include
everything you need to easily do it yourself.
Repack all road canisters at the first signs of packing material
deterioration. Part #005-10038
Repack all offroad canisters after every 10 hours of use. Part #005-10038MX
NEVER dyno test your bike with carbon fiber or titanium canisters installed –
the intense heat and lack of cooling air can quickly burn through the canister
material. Two Brothers Racing does not provide a warranty for burned
canisters.
