The day’s racing saw Adams, Webster and Robbo Lovett each take a win, with the round win going to Adams, despite both he and Webster finishing the day on 65 points.
Webster’s performance saw him overtake Jayden Rykers who went into the round in second place, while Adams held on to his lead.
Fellow local Chris Bosnakis is still second for the quad championship, despite winning the round.
He beat home track favourite Luke Gaisford in the first two races.
And he had the lead in the third but a mistake by Bosnakis almost sent him over the bars and allowed Gaisford through for the win.
Bosnakis is now only 11 points behind championship leader Anthony Pearce.
In the pro open, Louis Calvin remains the championship leader after winning all three races, despite crashing in two of them.
Webster and Adams took second and third for the round, with Webster in second overall.
