Just looking at the smoke in youtube videos is enough.<br /><br />Two strokes are also disappearing from the outboard motor world. I have a 2 stroke 3 HP outboard that weighs only 35 lb. The new four strokes are quite a bit heavier, but much cleaner burning.Lost Motorcyclisthttps://www.blogger.com/profile/08873504561959138792noreply@blogger.comtag:blogger.com,1999:blog-2156536327610779049.post-18995978961591378972010-02-17T08:48:44.983-05:002010-02-17T08:48:44.983-05:00Two-stroke road motorcycles in North America were ...Two-stroke road motorcycles in North America were 'killed' because of their level of emissions. As much as 50% of a two-stroke's fuel may be exhausted as unburnt hydrocarbons (UHC’s), along with much of the lubricating oil. Carbon monoxide (CO) and particulate (PM) levels are also significantly higher than with 4-stroke engines. <br /><br />Although, on a per-displacement basis, they perform better than four-strokes, the engines do not last as long, and tended to 'coke up,' with spark plug fouling a constant issue.<br /><br />In fact, the very popular <a href="http://en.wikipedia.org/wiki/Kawasaki_triple" rel="nofollow">Kawasaki <i>Mach IV</i></a> <i>triple</i> even had a fitted compartment under the seat for three spare spark plugs!<br /><br />Although they've largely disappeared from North American roads, two-strokes still make up the majority of road traffic in Asia. Estimates suggest that there are <a href="http://www.cleanairnet.org/caiasia/1412/articles-69725_report.pdf" rel="nofollow">hundreds of millions</a> of two-stroke motorcycles and three-wheelers on Asian roads, pumping out the emissions equivalent of over <b>five billion</b> modern automobiles - a serious environmental problem.<br /><br />Of course, no discussion of two-strokes is complete without mentioning the infamous East German <a href="http://en.wikipedia.org/wiki/Trabant" rel="nofollow">Trabant</a>! The <i>Trabi</i>, of course, was the 'peoples' car' of East Germany, produced in the millions, and helping to create that sooty depressing ambiance which most western visitors to East Germany invariably mentioned.Madeyehttps://www.blogger.com/profile/02593933575568389288noreply@blogger.com
