Care & Cleaning
Keep system free of dirt and moisture. Store in a cool, dry place. For cleaning use a mild spray cleaner. Always
apply cleaner or polish with a soft, clean cloth.
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.
Chrome Header System: Chromed header tubing will turn blue close to the exhaust ports, this is normal. To pre-
vent corrosion you must keep the header pipes clean.
Carbon Fiber & X-Metal Mufflers: X-Metal CF canisters will shift color from their original silver color to an amber
color after a few heat cycles, similar to the way our stainless steel headers shift color. Always make sure the fiber-
glass packing inside is in good condition and not burned out, as exhaust heat inside an empty canister will deterio-
rate the Carbon Fiber / X-Metal CF sleeve. TBR sells repack kits (TBR part # 005-10038) that include new rivets
and repack material as well as a drill bit (#30), making it easy to do yourself. Also, NEVER dyno test your bike with
carbon fiber mufflers installed - the intense heat and lack of cooling air can quickly cause the CF material to burn.
Two Brothers Racing does not provide a warranty for burned carbon fiber.
Aluminum Mufflers: Use an aluminum or mag wheel polish such as Mother’s to restore the bright finish to factory

1. After the transmission (3 or 5 speed) has been installed

you are ready to install the clutch.

2. Make sure that the crankshaft spacer is installed over the

crankshaft as shown. If you installed a stroke up kit and
replaced the crank, the crankshaft spacer is probably still
on the stock crank. Remove it and slide it over the crank-
shaft as shown along with the primary gear as shown.

3. Install in order as shown:

1. Lock Washer
2. Conical Spring Washer
3. Clutch Bearing

4. Tighten the clutch bearing to 29 ft. lbs.

5. Using a hammer and a punch, gently fold over one of

the tabs on the lock washer into the clutch bearing slot.
