Arnie Shelton is edging closer to his elusive first race win after securing his second successive runners-up spot on Sunday.
The Haconby rider was just 5.8 seconds off the 125cc race winner and series leader Tom Carne.
Shelton, who was delighted with another podium finish, now boasts a 14 point advantage over third-placed rider in the series, Peter Sutherland.
Shelton said: “It was probably my best race so far.
“The bike was fast, the team worked well and I got a good, clean start.”
Racers on 125cc bikes are on the circuit alongside bigger bikes but Shelton, who qualified in sixth place on the grid, beat all but two of the more powerful machines.
He added: “I was close to the front and thought I could have mixed it with the front two. About two thirds of the way through I thought I could reel Carne in but just could not go any faster.
“Last time it was eight seconds and before that it was 20. We are getting closer and I was close to taking first place for the 125cc bikes in qualifying.
“I’m not giving up until I win one.
“Tom Carne has a good team and is a talented rider but I know I can beat him. Brands Hatch and Cadwell are coming up and they are my sort of circuit.”
Shelton thanked Philip and Joy Sherwin for their sponsorship.
