The remainder of on-track activities Friday at the AMA Superbike Championship event at Infineon Raceway have been postponed due to rain. A light rain began to fall at approximately 11:05 a.m., causing the first Formula Xtreme practice session to be red-flagged after 15 of its scheduled 60 minutes. Full, dry practice sessions for the Supersport and Superbike classes had already run. The Superstock class did not get on track Friday. Once the rain started, it continued into the afternoon. At 3:00 p.m., AMA Pro Racing officials met with Infineon Raceway officials and decided to postpone the rest of the day’s on track activities, which included Superbike and Formula Xtreme qualifying sessions. If Saturday’s qualifying sessions are rained out at Infineon Raceway, procedures are in place to set the grids by using practice times and/or point standings, depending on the circumstances. No revised schedule of events will be released until Saturday morning. The likelihood of racing on Monday at Infineon Raceway is small, according to statements made by AMA Pro Racing Road Race Series Manager Ron Barrick during Friday’s rider’s meeting. Barrick told the riders that the television production company cannot stay on Monday and that isolated rain showers are forecast all weekend, including Monday. This year’s AMA event at Infineon Raceway was moved from early-May to two weeks later in May in hopes of having better weather. Ironically, the early-May weekend had near-perfect weather, according to one Infineon Raceway official.
