After a delay of an hour for an oil spillage at Parkfield to be attended to, the four-lap Senior was led away by Kenneth McCrea (Suzuki). Next were the Jackson brothers and it was Alan (Kawasaki) who took the early lead.
He broke Davy Morgan's 2004 outright lap record by an incredible 14.1 seconds when he returned 18 minutes 31.45 seconds, an average speed of 122.207mph from a standing start!
Second, 15 seconds behind came Junior race winner Ian Pattinson (Suzuki) at 120.613mph and third, a further four seconds back, was Seamus Greene (Suzuki) at 120.613mph. Fourth was McCrae, fifth John Burrows (Suzuki) and sixth Simon Fulton (600 Honda).
Jackson appeared to slow a little towards the end of lap two, while at the same time Pattinson opened out. Jackson still led by eight seconds as they pulled in to refuel, but as they exited Pit Lane Pattinson had taken over by two seconds. Greene was also striving hard and was only three seconds behind the top two, with McCrae, Burrows and Barry Maguire (600 Suzuki) moving to sixth.
The third leader of the race took over on the run to Ramsey for the third time. Greene moved to the front, leading Pattinson by 4.30 seconds, with Jackson down to third 1.75 seconds away.
As the third lap was completed, Greene stayed ahead, leading Jackson by 5.45 seconds, with Pattinson 2.78 seconds down. Tremendous racing.
McCrae, Maguire and Burrows were the second trio. Maguire's effort was more laudable for being on only a 600cc machine.
At Glen Helen, Green's lead was 9.29 seconds, with Pattinson 11 seconds further in arrears and McCrae unable to respond. At Ballaugh Greene was 9.67 seconds up, with Pattinson leading a fading Jackson by 18.30 seconds. At Ramsey Greene hadn't quite caught Pattinson on the road, but wasn't far behind, and leading the race by 9.23 seconds. Jackson was clearly struggling and was 32.01 seconds behind Patterson and only ten seconds to the good over McCrae.
Down the Mountain they thundered, with Greene's sights firmly set on catching Pattinson to finish first on the road and in the race. At the Bungalow the lead was 9.32 seconds but in the final few miles Greene forced past to lead over the line by a fifth of a second and take the race win by 10.2 seconds. Third was Jackson, 44.42mph back, but 10.2 seconds ahead of McCrae, with Maguire and Burrows fifth and sixth. Lap and race records went bust, with Pattinson also beating the old race record.
