Whats your max speed (flat)

[FoxMcCarther]

Hello, I've been stalking these forums for a while now, and I feel like my bike is a bit slower than many of the numbers I read here (granted not by much).

So, What are the max speeds (no incline or decline) your bike can reach in a reasonable amount of time (under 20 seconds or so in 5th gear), and what is you max downhill speed.

Also, I am not yet a very mechanically inclined person (getting better every day though), but what relatively simple things could I do to coax an extra 5-10 mph or so out of the bike all around (I'd like to be able to go along at 60-65 a bit more smoothly (I plan on installing the 16t front sprocket soon (which will help a bit with the smoothness and speed on the flats and downhill, but reduce my uphill speed a bit in 5th? (In theory, shouldn't it add ~2-3 mph on flats?)), but beyond that, what easy things can help?

I am aware of the performance mod section here, but I don't yet understand what some of them actually effect.

I am 5'10" at 175lbs, the wheels are stock, my 'average' max speed is about ~62 mph (struggles to keep up at 55 at anything more than an incline), the fastest I have been able to get it (downhill, wind at my back) was 74mph.
