Clean Air Mod Block Off Plates

Your motor deserves to look as good as the rest of you bike. These plates are a direct bolt on to your valve cover to delete the clean air valve ports when installing a clean air mod to keep oil out of your air box.

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'd billet aluminum

There are four reasons why you want to remove the air injection system from your bike.

1. To eliminate the connection of the breather hose from the engine case to the air box so that oil and hot vapors cannot enter the airbox and potentially hydrolock your engine (if the bik is dropped on its side)
2. 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.
3. 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.
4. This addition will typically remove the majority of popping on deceleration that can be experienced with un-burnt gasses within the emission charcoal chamber.

Note: Proper tuning may be needed and this is general feedback.
