Ryan Farquhar won the Senior Classic race on Monday

The Ballymoney rider won by 72 seconds at 108.08mph with Neil Kent second and Brian Mateer in third.

Dunlop was only 11.45 seconds ahead of Brian Spooner with one lap to go but the race was effectively over when the Englishman retired at Sulby.

Ollie Linsdell from England won a shortened Ultra Lightweight race from Tim Sayers and Joe Phillips.

The Clerk of the Course declared the result after three laps due to poor weather.

Lindsell went round at 107.197 to secure a 56 seconds margin of victory.

Dunlop was the Ultra Lightweight Newcomers winner at the Isle of Man meeting in 2005.

Ryan Farquhar's hopes of his second win of the week were dashed on Wednesday.

Brien was runner-up in the class last year but he finished ahead of Sweden's Mats Nilsson in Wednesday's race.

The winner also bettered Jason Griffiths' 2003 lap record by five seconds at 102.72mph from a standing start.

Former winner Chris McGahan claimed third ahead of John Goodall, Steve Elliott and Tony Myers.
