totally wrong assumption in my opinion..
ALL motorized equipment with gas or diesel engines have had to meet epa new standards and most if not all have exceeded older engine life sixfold and as well much increased reliability...except for the most part the snowmobile industry...
So tell me...why do all the others have the brains to work with EPA living with less oil and gas with increased engine life/milage and reliability but the sled industry seems to be one of the few that cannot..??
The EPA is a barrier im certain...but not an excuse..
Your reading and comprehension skill seem rather limited. I have already adressed this in an earlier post. The FACT is, Cat has NOT, thus far had to meet the same standards as Doo and Poo. They accumulated credits from the EPA for selling enough 4 strokes in their fleet. The thrttle body injected Cat motor does not meet the same standards as Poo and Doo motors currently. Ask the Doo guys how theri motors used to last... pistons every season was the norm. Even the early e-tec motors had a recall for new pistons by 1200 miles. Doo seems to have gotten on top of it, Poo is still struggling a little but getting much better by most reports.
Two strokes are very different than four strokes, I love th analogy to the automotive industry but it really doesn't apply. OR, you could ask the deisel truck guys what they think of EPA mandates that have ruined deisel fuel economy and reliability for the sake of emmissions.
It is OK to not pay attention but it makes you look kind of silly when you try to do that AND argue a point.
