John McGuinness proved too quick for Britton and Farquhar

Northern Ireland's contingent was unable to add to Adrian Archibald's Formula One victory from Saturday in Monday's action at the Isle of Man TT.

Archibald had high hopes in the Production 1000cc race but New Zealander Shaun Harris set the pace all the way and claimed victory, 16 seconds ahead of his compatriot Bruce Anstey.

Ballymoney native Archibald was in third place for almost half of the race but he ran out of petrol nearing the pitstop at the end of the second lap and eventually had to settle for eighth.

Ryan Farquhar took third some 20 seconds behind Anstey to register his second podium finish of the day while another Ulster rider Richard Britton was fourth.

Earlier in the day, John McGuinness and Chris Palmer claimed comfortable wins in the 125cc and 400cc events.

Englishman McGuinness, on board a Honda, had 26.32 seconds to spare from Enniskillen rider Britton in the 400 event while another Northern Irishman Ryan Farquhar was a further 16 seconds back in third.

McGuinness led all the way and admitted that everything had gone perfectly in the race.

Dunlop had to settle for fourth in the 125 class

"That was fantastic. I had absolutely no problem at all during the four laps," said McGuinness.

"Once I got past Richard (Britton), it was just a matter of keeping things ticking over and I turned it down a bit on the last lap just to make sure, I made it home".

Britton was content with his second place although he did nearly have a mishap at the pitstop when he almost collided with a race official.

Farquhar's third place was his first TT podium finish and he described himself as "happy enough" with the outcome.

Isle of Man-based veteran Chris Palmer had over 39 seconds to spare from England's Michael Wilcox in the 125 event while Ian Lougher was just over a minute behind the winner in third.

Robert Dunlop, who had spoken of his huge desire to claim a sixth TT win, had to settle for fourth place, a minute and 26 seconds adrift of Palmer.
