Le Viellez recorded a win and a second place but a fall in another race resulted in a fifth-place finish at the Jersey Motorcycle and Light Car Club event.
However, his points accumulation was enough to see him finish top, pushing Kieran Gregory and Declan Hussey into second and third places respectively.
It was the final championship race meeting of the season and the only championships to be decided were MX2, Grand Final and Adult overall titles in the Adult A group.
Sam Allix had won the first two races on his Honda 250 four-stroke bike and even with one race to go, Allix had secured the MX2 championship from Le Viellez.
However, it was the Grand Final which held the most excitement as both Le Viellez and Allix were title contenders.
