I work for emissions testing here in Washington state, USA. While we do not test bikes here, I do know that ALL vehicles manufactured since 1981 should be easily able to have HC below 220 PPM (part per million) and CO less than 1.2%.
This is for any non loaded engine both at idle and non loaded at 2500 rpm.
Personally I feel it is even better if the numbers are below 100 ppm and 1%. In simple english HC is "unburned fuel" and CO is "partially burned fuel". So if you have smaller numbers you have more power to the wheels, and better mileage.
Just my 2 cents worth.
