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.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e3. 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Graves Motorsports","offers":[{"title":"Default Title","offer_id":31550376247376,"sku":"AB014","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0081\/7695\/9568\/files\/Honda-CBR250R-Smog-Plate__08648_047dcc13-8fa4-41e9-8885-391294527266.jpg?v=1771395431","url":"https:\/\/bills-exhausts.us\/fr-my\/products\/ab014","provider":"Bill's Performance LLC","version":"1.0","type":"link"}
