2 strokes are made to rev high. When the weather's right my motor SCREAMS! About the time I think it's gonna blow up I'll still get even more revs out of it and just keep on goin'. Only problem I've had so far is it will heat up to the point that it starts to bog down. With my shift kit, I can hit an easy 46 mph on a flat road, 50 mph when the weather's right. When I say "the weather's right" I'm only guessing but it seems humidity has some effect on my air:fuel ratio.
