Graves Smog Block Off Plates

Product 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). Once these are capped off, the air injection system can be safely removed.

  • Made from machined aluminum.
  • Sold in pairs.

There are two reasons why you want to remove the air injection system from your bike:

  • 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.
  • 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.

Does not match with my bike

This website matched up these smog plates with my 2008 ZX10R. But they dont fit my bike, Ive tried another brand from this web site. They also dont match my bike. The other brand was called Driven. This product only fits Yamaha bikes.
