I would think 3000RPM is too low.I mean just riding around the city Ive been changing up between 3-5k, does this seem about right?
Shift when you're far enough into the power to not drop below it in the higher gear.
I rarely get above third gear around town on any of my bikes or cars. If I can get up to about 80kph I'll grab fourth. I never use sixth on the bikes or fifth in the cars unless I'm out on a highway somewhere.
