Looks like this might be heading for a single stroke at ten paces to settle.

Any technology that produces these bikes is worth hanging on to,
I rest my case...

2 strokes are live and well in the outboard motor industry.
I have a new 75 HP Mercury Opti- Max that's cleaner burning and effecient than the compair able 4 stroke.
Gets better fuel economy and is fuel injected.
Not sure why they haven't started building them for the auto industry frankly.

I thought two-stroke boat motors were being phased out.

Here's an interesting overview of the way forward for the supercharged, pressurised lubrication 2-stroke.

Two-strokes are alive and well in the snowmobile industry. Technology has done wonders for them. My Arctic Cat HCR is a direct inject 800 cc two-stroke, and I can attest from experience that it will run upside down. Four-strokes are coming on strong, and you really cant touch them for top end, but to get there you have to turbocharge or add nitrous, a lot more complex and expensive than my two-stroke.

As far as the environmental concerns, I think it just goes to show the stupidity and narrow-mindedness of your typical person. They see smoke and smell exhaust, so therefore, two-strokes must pollute more. Let's not consider the extra cost in energy and raw materials to make all of the extra parts for the four. My sled has an exhaust can on it instead of the bigger suitcase style muffler, but it still meets noise limits. I'm not really sure if a four-stroke is louder, but it is a more distinctive sound.

Sorry, throttlejockey154, but if one can see smoke and smell exhaust, it's a reasonable assumption that the motor is polluting more than one without visible smoke and smell, although there's more to it than just that, nitrates, hydrocarbons, sulfur and so on.

You just cant see or smell the smoke from the factory that has to make all the extra parts for the four. I can't either, but I know it's there.
