Lowry led the championship after two rounds but could only manage 13th and 21st place finishes on Monday.
Alastair Seeley took sixth and 11th positions to lie sixth overall while Michael Laverty was seventh and 12th and he is 11th in the standings.

Ballymoney rider Dunlop is now third in that championship.

In Sunday's British Superbike race, Seeley had achieved a creditable fourth place finish, with Laverty sixth.
Tommy Hill, Chris Walker and Shane Byrne helped themselves to victories in the showpiece Superbike races over the weekend.
Hill leads the championship by six points from Tyco TAS Suzuki ace Josh Brookes, with Byrne third.
