The Kirton rider travelled across the Irish Sea to compete on the Emerald Isle for Gearlink Kawasaki.
Wilson was reunited with his 600cc Supersport machine and, despite the fact he had not ridden it this season due to his British Superbike commitments, he was soon back on the pace.
He qualified in third place to start his two Supersport races from a front-row grid position.
Wilson completed the first race in third place.
Later in the day he went out for the second race which was run over eight laps of the 1.415-mile course, and this time he was fighting for the lead with teammate Glenn Irwin.
The two Gearlink Kawasaki bikes pulled well clear of the pack and Wilson completed the race just a fraction of a second behind Irwin for second place, and well ahead of old rival Alastair Seeley, who finished in third.
“I really enjoyed being back on the little 600 and I can’t thank Gearlink Kawasaki enough for giving me the chance to ride it again,” Wilson said.
He then went on to contest the two Superbike Pro races on the bike he has ridden all year for Gearlink Kawasaki, finishing second behind Danny Buchan each time.
He then rode in the feature race, The Jas Finlay Sunflower Trophy event, which was run over 10 laps.
Wilson got the hole shot at the start, but he was pushed wide by Irwin, who then crashed causing the red flag to halt proceedings.
At the re-start Wilson once again took up the lead which he held for three laps.
But despite all his efforts he was unable to stave off the attentions of Danny Buchan, who managed to make a pass on Wilson and went on to take the win with the Kirton rider right behind in second place.
“We all had a great time at Bishopscourt,” Wilson added.
“I have to thank Gearlink Kawasaki for the hard work put in this weekend to make sure the bikes were in pristine condition.”
This concludes Wilson’s race programme for the year.
