Jeez, I think I need to practice......or at least pay some attention to what my bike is running. I have so many questions now, I don't know where to start. First I will go out and let you know what I think I'm doing. You guys are creating a motorcycle monster here, just so you know......)Storm, low RPM's in higher gears it not a good thing to do and 2K is a bit low in the upper gears like you are doing. I always say, if in doubt, downshift. I feel a comfortable area is around 2500 myself as far as how low you can go in the upper gears.
