Your post brought memories back to when i was at Pfaffenhofen for the World U21 Final 1982, Loram had completed his 5 rides, it meant if Adams won his last ride he won the meeting.
Adams was off gate 4 and Dave Norris off gate 3, remember Ian Thomas & John Berry giving Norris a right talking to, telling him he must stop the run of Adams on the first turn.
Thomas last word of advice to Norris was, make the gate and don't turn left till you hit the fence!!! Happy days
