From the Live notes transcript that was running on the day - Start from the bottom and read up

• 1303 - But the wily veteran John Allen managed to use his better corner speed on the final lap through the last turns to get the upper hand on Fripp and held it to the line to take second place.  McMartin took the win by 1.5 seconds, Jamie Aitken home fourth
• 1302 - Fripp's Ducati is fast, Allen can sit on his tail through turn 1 and 2 but as soon as they hit the back straight Fripp just walks away from him.  There must be 20hp or more difference between them
• 1300 - Archibald has pulled in to retire after drifting further down the field.  McMartin the clear leader, Fripp in second place but still has John Allen on his tailpipe
• 1258 - Stuart Fripp then closed and overcame Archibald to take second place with five laps to run.  Archibald had drifted back to fifth place while his teammate John Allen has promoted himself to third place
• 1256 - I suspect that the Aprilia guys have tuned themselves to a standstill during the break between their races.  In the first race McMartin could pull no ground on them down the straights but in this one his Ducati is stomping all over the Aprilias which seem to have lost some power during the break.  Perhaps playing with their fuel injection settings in the break has resulted in them going backwards.  As a result McMartin closed and passed Archibald on the second lap and then started to pull away
• 1254 - Twins out now for their second race and Archibald survived the turn one and two madness to lead them around and the diminutive Aprilia rider managed to pull a full second over McMartin on the opening lap.
