Speaking of Harleys.....
Motorcycles emit 'disproportionately high' amounts of air pollutants
Motorcycles collectively emit 16 times more hydrocarbons, three times more carbon monoxide and a "disproportionately high" amount of other air pollutants compared to passenger cars, according to a Swiss study to be published in the Jan. 1 issue of the American Chemical Society's journal Environmental Science & Technology. The study, by Ana-Marija Vasic and Martin Weilenmann of the Swiss Federal Laboratories for Materials Testing and Research, found both two- and four-cycle motorcycle engines emitted significantly more of these pollutants than automobile engines. Particularly worrisome are the high levels of hydrocarbons emitted by Japanese, German and Italian two-wheelers, according to the study. Some hydrocarbons have been linked to global warming, while others are suspected of being carcinogenic. Motorcycles aren't a primary means of transport in most developed countries, the authors note. As a consequence, they say, "the importance of [motorcycle] emissions has been underestimated in legislation, giving manufacturers little motivation to improve aftertreatment systems." Until recently, for instance, U.S. emission standards for highway motorcycles hadn't been updated in 25 years, despite the fact that these vehicles produced more harmful exhaust emissions per mile than cars or even large sports utility vehicles, according to the Environmental Protection Agency. However, a new EPA rule, which goes into effect in January, will require manufacturers to reduce combined emissions of hydrocarbons and nitrogen oxides in motorcycle exhausts by 60 percent. When the rule takes full effect in 2010, the EPA estimates it will reduce emissions of these pollutants by about 54,000 tons a year, and save approximately 12 million gallons of fuel annually by preventing it from evaporating from fuel hoses and tanks.

Speaking of Harleys.....
Looking outside... across my veranda, the "moose" thermometer is hovering
around 12C (that's +10F0. which OK... after all it was -20 this morning (-4F). I'm fairly sure that my scooter was one of many NOT spewing filthy clouds of fetid fumes and such skyward......I can't say the same for the 20 or so cars and light trucks patiently waiting to warm and start their day that I can see from my front door. I dare guess that my little bike wont see pavement until May, at the earliest (and that's because I pull my bike out about a month before most). So, you are quite safe up until then..... unless you happen to come to a stop near one of those clean burning gutted cat, O2 simulator equipped, overcammed daily drivers we hear about. Last year, weather and chores allowed me to ride my scooter to te Ford Training Centre in Edmonton only once. The trip down and back plus three evenings of visiting in the city... the DP about fell out of his chair when I turned in gas receipts for 11 bucks.... the same trip in my pick up costs ten times that. Now.... let's bear in mind that this study seems to have been done in Europe... where, AFAIK, there is very little in the way of emissions controls, nothing even similar to the CAFE standard and gasoling quality may be suspect. With these assumptions in mind, I might even agree with the study and opine that perhaps those damned Europeans should clean up their frigging act. FWIW, Harley Davidson started using emissions control some time ago.... it started with preset mixture adjustments on carbs on all models and by about 03, the large displacement scooters had even fuel injection available and, from what little I can find to read, are fitted with catalytic converters. Now... what was it you were saying? |

My 2004 twin cyl Beemer has a CC and the preceeding models for at least a decade have as well. What the article missed is that the polution standards are lower in Europe, hence the higher % of diesels. |
