It's a different world riding here with 25 to 30 mph headwinds and hills with larger than 5% gradients for more than a half mile. I actually think my weedie powered bike is better at long hills as it's geared at about 27:1, and it's forced aircooled.
lots of hills here too, and wind. i jet mine a tad rich just because of it. it get a bit of four stroke with out a good load. once warmed up and i get going, it hits a power band going up hills and in the wind. well hits lower then without the load. extra gas helps keep the engine cooler.
