Martin Jessopp left it late to snatch the top spot during opening qualifying for the 49th Suncity Group Macau Motorcycle Grand Prix.
The Riders Motorcycles BMW challenger knocked former winner John McGuinness (Honda Racing) off the top spot at the end of the first session to assume control at the head of the times by only 0.051 seconds.
Michael Rutter, the most successful ever rider at Macau with eight wins, was third fastest on the Penz13.com BMW, just over a tenth of a second behind Jessopp, with Austrian Horst Saiger right in the mix on his Kawasaki in fourth.
Yorkshireman Ian Hutchinson also clocked a late fast lap on the PBM Kawasaki to climb to fifth ahead of Louth's Peter Hickman (Briggs BMW), who only made his debut at the Guia street course in 2014.
Northern Ireland's Lee Johnston, who will remain with Phil Reed's East Coast Racing team for 2016, was next on his BMW S1000RR Superbike as he completed the top seven, followed by Gary Johnson (Penz13.com BMW) and Aussie David Johnson on the Ice Valley BMW.
Last year's winner Stuart Easton was only 10th as the Scot gets to grips with the SMT Yamaha R1 for the first time, with Isle of Man rider Conor Cummins on the second of the official Honda Racing Fireblades in 11th position after FP1.
Ireland's Steve Heneghan, Didier Grams and Jimmy Storrar from Scotland rounded out the top 14.
