Re: Bicycle motor with a cat?
As to the pollution problem...ever think about how much pollution a single trip cross country in a 727 makes?
How about the fact that most trains leak more oil in an hour than a two stroke bicycle motor will use in it's entire service life.
Or all those idling police cars?
Ever follow a garbage truck? City bus? Big Dodge Ram diesel?
Or what about all that smoke that comes out of the top of a Bogus King restaurant?
