I understand your point. But in 2002 they decided for the 990 just to make double sure the new 4-strokes machines would beat the 500s. If they has introduced 800cc then they would have been trashed by the 500s. The output equivalent of a 500cc 2-strokes is roughly the 800cc 4-strokes they introduced later, when 500s could race no more against them. The equivalence of 2-strokes vs 4-strokes is roughly a 1.6 multiplier (you need 1.6 times the capacity of a 2-strokes to obtain the same power you get from a 2-stroke). But mind that at the same level of power, a 2-strokes always will accelerate better (and be a lighter engine).
It has all been a political decision, not technical. Those existing 2-stroke designs maybe had reached their peak, but surely not the 2-strokes concept which surely has plenty of room for development, I dare say even more than 4-strokes.
You haven't heard the riders complaining about the 'one Fast line 800's'. Pay more attention, and your opinion may end up more valid, another good thing to practice is finding a few positives, does the rest of the post read like I know nothing or just the bit you didn't understand? Don't end up like the other two in the minority I mentioned, for they are well beyond help.

Yet again you prove what a halfwit you really are.
Go back and have a look just who complained about the slowies
As much as I think direct injection two-strokes need to be developed, I don't think they are quite a magic as people make them out to be.
The way for direct-injection two strokes to make big power is to inject the air-fuel charge while the exhaust port is open. Even with expansion chamber scavenge, clean 2-strokes are still not emissions compliant, though they would still be badass on a track.
The easiest way to make direct-injection 2-strokes emissions compliant is to inject the charge while the exhaust port is closed during the compression stage. Injecting the charge during the compression stage basically turns 2-strokes into a 4-stroke engine. A 600cc clean 2-stroke allegedly produces a bit over 100hp, but at much lower rpm than its 4-stroke counterpart. Unfortunately, the lower revs does not equate to longer engine life b/c of the friction caused by an open exhaust port.
The only way to solve the problem is direct out-jection (or whatever you want to call it). If they could develop a system that sucked the exhaust gases out, it would solve the port problems. Clean 2-strokes would make the same power as the equivalent 4-stroke, but at half the rpm which would lead to engines (especially racing engines) with very long service intervals. It would be amazing.
YES, about time someone said it. Get the ABS OUT, NOW! And while they're at it I want the Turbo, NOS and super chargers gone as well, not to mention rockets they use for acceleration. Get et all OUT, NOW
That is in fact the easy part. While they forbid the sensors for ECU connection they would allow them to connect the sensors to a separate closed system for data logging. It would be just like going 10 years back in time as that was exactly the configuration most top teams used up to that time.

800 lovers are ....... .......
990s ruled http://www.powerslide.net/forum/public/style_emoticons/<#EMO_DIR#>/.....gif
Dude, the extra 200cc are MEANINGLESS!
They ruled because of limited electronics and no idiotic fuel restrictions.
1000cc and 21L of gas be just as '........' as the current 800 series.
The 800s can be made fun again simply by adding a liter of gas. After that, add 1/2 a liter per year. That will allow slow progress on absolute power w/o the factories needing to spend a zillion dollars in a single year trying to develop an EffWun level engine overnight.

i agree the fuel and over load of electros would .... up the 1000s.... but the 800 will/would/can NEVER put out the torque a 990/1000 can..and Torque ladies and gents gives me a ragging boner

If you are all the "Torque" you make out to be, then why are you picking 1,000cc 4's ??
They aren't exactly "Torquevana"

900cc bikes it is then!
no no we need a grid full of those MT01's if curve wants "Torque" .......
