I believe Swap is referring to my reference of 2-strokes disappearing from pro MX and SX.
Well, I didn't state myself too well in trying to defend 2-strokes to several 4-stroke lovers whom everyone seems to adore now.
To clarify, 2 strokes have been edged out of Pro MX and SX, basically from misinformation and eradication by the OEMs (of course this has come from pressuring the AMA to allow unfair rules for the 2-stroke in AMA Pro Racing). This has caused the 2-stroke to virtually disappear from AMA Pro MX and SX, and the GP classes. This is very disturbing and there has been an ongoing effort to get them back in (petition, letters, phone calls, etc).
The reason for this eradication put forth by the 4-stroke guys in this thread, is that 4-strokes are a far better racing machine, and if anyone could get on one they would see how great it is. Furthermore, they said that they wish that 2-strokers would quit ramming 2-stroke verbage down their throats, and just open their minds to the wonder of the 4-stroke.
I have agreed that many people can go faster on a 450F or 250F than their AMA legal 2-stroke counterparts (250 and 125). But I went on to mention that this is not the issue at hand, and that even though the 2-stroke IMO is a viable alternative to a high tech, high dollar 4 stroke, efforts need to be made to further the 2-stroke cause so that what has happened in Pro MX and SX won't spill over into the other disciplines, like Off-Road racing (which is strong for now).
