After modding both 'old style' two-strokes and stratos, I look at the old style as an inferior design. It isn't just emissions and fuel economy, the stratos can put out more power.
I no longer call the old style two-strokes as 'conventional' two-strokes, as they are no longer the accepted design, they are past their time. They are 'old style' and will slowly fade into obsolesence.
Its funny that three years ago that this site had a negative attitude about stratos - 'they can't be modded' was the big one. Well, that one has been put to rest, Crikey, if you're going to mod a saw, make it a strato - the design has more potential. It's kinda like the debate between wedge head versus hemi head engines, which one has the most potential to start with.
