The second of today's combined 125cc and 400cc was a virtual repeat of the first.
Alistair Howarth was again well on top of the task in the 400s, Brian Purdy and Dave Madsen-Mygdal completing the podium.
After disappointment in the 250s Chris Palmer took his second 125 win of the day only just pipping William Dunlop. Ian Lougher couldn't repeat this morning's second place and had to settle for third.
