Saw in the "what every newbie should know" section that a low, lumpy idle is not good.  Suggestion is to get idle at 1000 rpm.  How do yo know what the RPM is without a tachometer?

It's fairly easy, find a level piece of road ,put the bike in first gear,and without the throttle open, set the idle so the bike runs at ten mph when the clutch is fully released.
