Wet weather on the Isle of Man rendered Thursday evening's qualifying sessions for the Manx Grand Prix almost meaningless as the riders took a cautious approach. Clerk of the Course Phil Taubman warned the riders about lack of adhesion all round the course and with further rain predicted later in the session, Wednesday's times remained intact.

Grant Wagstaffe and David Lumsden led the modern bikes out at 6:30pm and it was Wagstaffe who clocked the quickest time, lapping at 107.700mph on his first run before improving to 111.003mph on his second. Meanwhile, Wayne Hamilton set the pace in the Supertwins despite this year being his debut in the class, lapping at 100.117mph.

In the classic Superbikes, Michael Dunlop led the way on his Suzuki XR69 with a 104.283mph lap ahead of Mick Godfrey and Mark Buckley whose lap in the dry Wednesday evening session keeps him top of the overall classification.

Paul Coward was the fastest Classic 500cc on the '71 Nourish Westlake while Chris Palmer was again fastest in the 350cc Classic Class on the 1972 Drixon Honda. Palmer and later topped the Junior Post Classic times too, lapping at 100.580mph on his '91 Yamaha TZB.

Qualifying continues on Friday night before the Newcomers get the racing underway on Saturday.
