snobuilder, I hope I am taking your post correctly and I have to say I completely agree, a few years back we were led to believe the 2 stroke was going away and look where it is now, weather it is a snowmobile, outboard, dirt bike, lawnmower, chainsaw, etc I too think they are picking on too small of an industry in the scheme of pollution,, yes I feel they needed to run more efficiently and look at the technology we have as a result but I agree the EPA are picking literally on a "Gnat on the hair on an elephants back" and I also agree on all the "do gooders jetting across the planet" or what about all the Space X rockets that seem to go up on what almost seems like a day to day basis, you never hear what these thinks do to our atmosphere or o-zone layer, oh but wait...... these things are a necessity. I hope I read your post correctly because I do agree too much effort, money and research being wasted on such a small industry as far as pollution goes and again although the technology that has come as a result of is impressive, there are much bigger polluting fish to fry. I'm sorry if I read into it incorrectly and apologize for the rant.
