ChrisUSA should be qualifying in the top 10 on the grid

just relishing this final grand prix season before the big rules change and wanted to post a message about my beloved 2strokes. let me list a number of reason's why i believe the modern 2stroke to be a superior engine:

Piston For Piston:
Way more horsepower
Much lighter
Much less expensive
Amazing sound
Amazing smell
Equally reliable
Way easier to work on
Way less expensive to work on
Did i mention way more horsepower?

Imagine a world of only 4stroke engines. A guy goes into an engine manufacturing plant, goes up to the lead engineer and says "what would you say if i told you i can build you an engine with 70% less parts, 40% smaller in size and 50% more powerful? "Impossible" says the engineer.
This basically sums up my feelings for the 2stroke. The greatest mechanical invention ever.

So why isn't the world beating a path towards the 2stroke door? EMISSIONS. Dirty exhaust and plenty of it. and the world has determined that dirty emissions outweigh all its benefits.

Direct-Injection has eliminated the "dirty exhaust and plenty of it" factor, but has added cost and complexity. Who cares?! Get it into production, i'll buy it

Not to mention valves. My fav kind- rotary. And plenty to choose from- plain, Cross, Aspin... And none of them are so common and lowly as to actually protrude into cylinder.
And I must have a pint of racing castor oil, in the back of my garage. Burn that with gasoline and 'tis the best scent I have ever smelled.

BTW, pardon my relatively poor English, but what does 'piston for piston' mean?

And I think emission problem has not been adressed (and dealt with) with sufficient care.

let me clarify

piston for piston, i meant it like saying "pound for pound", although if i used pound for pound i wouldn't have been able to say "lighter weight"

Agree with you guys and it is a fact that the two stroke enginedesign is far more efficient than four strokes.
Onlt reason it hasn't taken off I guess is the tooling costs for big manufacturers and the emissions problems, though it has been proved that a stroker can be made more efficient than a diesel as Honda did a few years ago.
EFI would also help, dufficult to map for a stoker though as so few moving parts and gases mixed all the time.
