For a 1982 R4, the springs are there to pre-tension the gear lever mechanism, so when in neutral the gear knob is biased towards the 3rd/4th gear plane. To select 1st gear, you should have to twist the gear knob to the left to engage the 1st/2nd gear plane. If the springs are missing, the gear selection will be not be so precise. When working properly, changing gear from 2nd to 3rd (with a very light touch) should be a straight push forward movement, with the springs providing the bias towards the 3rd/4th gear plane. Simple, but very effective....
