Going into the final round of the 1971 500 World Championship at St. Anthonis, Holland, Roger DeCoster and Ake Jonsson were locked in a close duel for the crown. Jonsson had won the 500 Luxembourg GP the week before and went to Holland with a one-point lead. Sadly, Ake’s Maico short-reach spark plug unthreaded in moto one and he had to stop and thread it back in by hand. He raced back to 10th and then won the second moto, but he lost the 1971 500 crown to Roger DeCoster. Ake would never win a World Championship title.
