Like they said in the other thread, motorcycles dont shift well when not moving, sometimes they will do it ok,sometimes not, but rocking it forward or backwards will get it in every time.
As for going right from 1st to 2nd, missing neutral, this is common when the engine/gearbox is cold. After riding for a couple minutes it should shift normally.
Also, please dont double post like this, it clutters up the board.
