Interesting to confirm about altitude power loss. The obvious only dawned on me out there: efi may self adjust to keep the mixture correct, but up high the reduction of available oxygen still adds up to power loss.
Must say I never considered a WR250X anymore than I'd consider Honda's CRF250X or CRF250R. AFAIK, all three are expensive, high compression, high performance, high maintenance dirt racers which would be wasted on my sort of riding.
A lot of rec CRFL dirt riders drop from 14T to 13 and claim great results when allied with Stage One power mods (that's how mine came). I'm not convinced it would have made that much difference for my sort of loaded cruising, though I will admit I don't like running an engine hard.
What is this mysterious 200cc Chinese dual sport you speak of?
