• A. Remove the heat shield and drill a 9 mm hole in the head pipe. Position the hole in a straight portion that is about 10-15 cm away from the exhaust port exit.
• Note): Be sure to check the position of the heat shield clamps as you DO NOT want the hole to be over a clamp mark.
• Note): If the hole position is too far from the exhaust port exit, the gases may not be measured accurately.
• Critical - make sure this location is approximately 1" to either side of the heat shield clamp.

• B. Install Rivet Nut using the hydraulic installation tool.
• Note): Follow instructions provided with the tad. Use reasonable force; you will feel when Rivet Nut is fully installed. The last pull on the handle will only go about halfway.

C. Attach the O2 sampler block to the head pipe using the supplied copper seal washer and the vented hexagon socket head bolt. Attach the silicone hose to the exhaust port jet on the O2 block. Please fix the silicone hose to allow the gases to flow using tape (or other means) to the frame (or other parts) so the hose does not get in the way while running.

Note): Make sure there is a copper seal washer between the rivnut and the O2 block as well as a copper seal washer between the head of the bolt and the O2 block to ensure that there will be no leakage of the gases.

Note): If the vented hexagon socket head bolt is excessively tightened, the bolt may break.

Note): If the rivnut moves, please retighten the rivnut.

Note): Be sure to fix the silicone hose so it will not be damaged and is free from creases.

• D. Secure the O2 block with a wrench (or by other means) and install the O2 sensor.
• Note): If the O2 sensor is tightened without securing the block with a wrench (or by other means), there is a possibility of breaking the vented hexagon bolt.
• Note): Route the o2 leads and exhaust tubing away from exhaust, hot engine components, and rear wheel. Using zip-ties, or Velcro ties, secure o2 leads and exhaust tubing.

• E. After tuning is complete, remove Wideband sensor and adapter block. Install stainless steel button head screw and a small amount of anti seize. Reinstall heat shields.
