I am having difficulty telling when i am in 6th gear on my 2010 Z. I have been riding an SV650 and could always tell if i was in 6th gear because at 80 mph my tach was at 6000 rpm. I am not used to an inline 4 engine and I see that the rev difference between gears is pretty small, often times in the neighborhood of only 500 rpms. Since the bike pulls so well at all speeds in all gears, if I had to shift gears on the hwy because of changing conditions, I often dont know if i am in the tallest gear and end up making an unnecessary attempt to upshift eventhough I am already at the highest gear. This is annoying. Does anyone look at the tach and match speed to determine if they are in the tallest gear? I want to stop trying to upshift when I am already in the tallest gear.
