He dominated the opening 1000cc contest and then added the 600cc race after a tight battle with Jamie Coward.
Lee Hembury came through the field to take the 600cc B Race - he was 9th after 2 laps of the 7 lap affair.
The closest finish came in the 250/650 race with Dominic Herbertson just crossing the line ahead of Rob Hodson.
