| Abstract | This report describes the testing of ten motorcycles for exhaust emissions of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). Emission rates in grams per kilometer are presented for the 1975 Federal Test Procedure and the Highway Fuel Economy Test, as well as in percent or parts per million for several steady-state conditions. The test motorcycles were equipped with 2-stroke, 4-stroke, and rotary engines ranging from about 100 to 1000 cc displacement. Several exhaust emission control techniques were applied, including minor and major carburetor enleanment with and without capacitive discharge ignition, secondary air injection with both pumps and reed valves, port liners, thermal reactors, oxidation catalysts, rotary valve modification, a spark ignited afterburner, and a short-circuited air-fuel mixture extraction system. Driveability, performance, and maladjustment (stock only) testing were also performed. All testing was performed with low accumulated distance on the motorcycles.
