Description: Graves Motorsports Smog Block Off Plates are designed to seal off the ports on the valve cover used by the air injection system (a.k.a smog pumps or AIS).
The air induction system (AIS) burns unburned exhaust gases by injecting fresh air (secondary air) into the exhaust port, reducing the emission of hydrocarbons.
Once these are capped off the air injection system can be safely removed. These Smog Block Off Plates are made from CNC'ed billet aluminum and feature the Graves Motorsports “G” logo. There are two reasons why you want to remove the air injection system from your bike;
1. If you are using your motorcycle on a closed course (racing, track days, etc.) you will want to remove all unnecessary equipment from your bike for reduced weight and ease of maintenance.
2. To get an accurate Air:Fuel (A/F) ratio when dynoing the bike. The air injection system pumps fresh air directly into the exhaust stream in order to burn off any unused fuel. Unfortunately by doing this the A/F ratio is thrown off by the extra “fresh air” in the exhaust stream. By removing the air injection system you can achieve an accurate A/F ratio.

Check out our all new hand-made-in-the-USA slip-on exhaust system for the 2006 Yamaha R6. The exhaust sounds great and is not to loud despite removing the stock exhaust silencer. This is because a majority of the sound damping is handled by the muffler under the bike not the exhaust silencer on the side of the bike.
This exhaust system features meticulously welds, laser engraved Graves Motorsports logo and a Moto GP inspired reverse cone megaphone design.
***This exhaust does not fit the 2006-07 Yamaha R6S***
