Canadian Clint McBain took pole position over Vesrah Suzuki’s Tray Batey in the Formula 1 class. Junge will start third while Acree fills out the front row on his GSX-R750. Opie Caylor rounded out the top five on his GSX-R750. Pole position in the 750cc Superstock went to Caylor with Acree second. GSX-R600-mounted Chad Lewin starts from third with Marshall fourth on another GSX-R600. Robert Jensen rounded out the top five. Open Superstock Expert qualifying was cancelled after an afternoon rainstorm moved in a few minutes into the session. Only three riders had recorded qualifying times when the red flag came out.
