Good advice and there is also the point that the gearing gap between first and second is usually pretty big compared with other gears.
As for revs to change at , any revs that will allow it to pull the next gear.. going slowly home with the fish'n'chips change low.... chasing down your mate on a sunday ride.. redlineIts all got to be good.
Just ride, enjoy, put smile on dial and they will get smoother, faster and quieter!!!
