Motorcycles pollute more than cars?? Watch the latest episode of mythbusters. Season 9 Episode 13 According to them, motorcycles are more fuel efficient, and produce less CO2, but they produce 100's to 1000's of times more Carbon Dioxide Monoxide and other harmful gasses than cars. Makes sense to me, because I would imagine there are more catalyst systems on a car. Food for thought. You must mean more CO, carbon monoxide. That's what the cat changes over to CO2. Some bikes have cats, not sure which ones. Bikes have gotten so expensive, and even without emissions gear, so complicated, that they are no longer, imo, the cheap, fun, easy-to-own bikes like my slow 1971 CL175 or troubled-but-gosh-I-wish-I-had-it-back '72 CB450, or my '74 XL250....or my '78 PE250, '81 PE400....'83 GL500... But I digress..... Quote: You must mean more CO, carbon monoxide. That's what the cat changes over to CO2. Some bikes have cats, not sure which ones.

But I digress..... Yes sir, I do thank you. I corrected it. They finished the testing with a bike that did have a cat, but it still produced more toxic gasses than a 2000 model year car. I credit this to major advances in emissions control (for better or for worse. I could argue that all day.) I think motorcycles must be exempt from some things that cars are not. They tested 80's, 90's and 00's cars and their companion bikes, every decade improved but cars where better in everything but CO2 IIRC. I figured it was because of no cats on the bikes. __________________ '51 F3 Flat8 '64 Galaxie 352 4bbl '72 F250 400/C6 '92 Grand Marquis '97 F150 5.4L '08 Bullitt #3947 Just smogged an '01 LS430. CO is measured at 0.01%. Doesn't take much to make a big multiple of that number. Seems to me I recall the AMA doing a lot of work to point out that there just aren't that many bikes compared to cars, so the impact of a higher standard is very small. NO at 1512 rpm was 0. Zero--a million times that is still zero last I checked, so you gotta watch the actual numbers on stuff like this, not just the percent. A standard way of getting what you want/avoiding what you don't--use the number, actual vs. actual, or percentage vs. prior, whichever looks more dramatic. They showed both the actual numbers and the percentage and put them in bar graph form, it was a very good comparison. Lot better than some of the vehicle tests they have done. They even had the bike follow close behind the car on the test drives so the traffic would be the same. __________________ '51 F3 Flat8 '64 Galaxie 352 4bbl '72 F250 400/C6 '92 Grand Marquis '97 F150 5.4L '08 Bullitt #3947 Posting Rules You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is On Forum Jump
