Hmmm.... Not sure what you're talking about. Seems most of your figures are just made up.
1)There are no emissions standards for ATV engines,
2)2 stroke engines (found on some ATVs) spew up to 300 times more hydrocarbons than an auto engine, and pollute much more by dumping 25% of their fuel in to the air and water (in the case of marine engines).
Finally - I don't know what kind of ju-ju you're practicing, but my Honda fourtrax gets less than 20 miles per gallon - 300 cc. Most utility ATV models are in about the 20 MPG range - less than my Ford pickup.
Maybe you should try looking up some facts and measuring your own MPG before writing more. An UNINFORMED pen is the most dangerous...
