But 2 stroke rebuilds are easy and cheap.
On the older air cooled bikes, I could remove and replace the cyl, rings and piston in 10 minutes easy.

All about 10 minutes. No kidding.
As for the liquid colled machines, sure its a lot more time work and money. This is why when it comes to 2 strokes, I own air cooled only.

There's nothing to debate. Its 2005 not 1975. Going back to 1969 I've owned a Yamaha 80, Kawasaki 90, Hodaka Super Rat 100, Yamaha DT1 250, Yamaha RT1 360 and Kawasaki 500 Mach III (all air cooled). I agree as long as you have all parts on hand a top end can be rebuilt in 10 - 15 minutes. I've lost count how many I've done over the past 35 years.
But I totally disagree with the leading part of your statement above which implied two strokes in general. They've come a long ways since the good ole days and air cooling. There is no comparison due to technology.
