You are correct regarding lugging, and winding out the engine.  You can hear the engine winding up to higher rpms. This sound is your signal to shift; don't look at the tachometer. Listen to the engine. When the rpms reach about 5,000-6,000 rpms, it is time to shift from a lower gear. |
I find with the 14 tooth sprocket, my RX3 likes to cruise at 6000-7000 RPM. It reaches peak power somewhere between 8000 and 9000. I generally shift above 6000 RPM ... a little higher on hills and maybe a little lower on the flats. Like Spud says, once you learn how that sounds, you'll shift by sound and by how the power feels, not by watching the tachometer.
