The low man on the totem pole under the Monster Energy Pro Circuit Kawasaki tent always has to run the O2 sensor on his bike. This week that's Austin Forkner. The teams pay a lot of attention to the weather here, to make sure they can get as much power out of the bikes, despite losing some to the altitude here. It's not as bad as Lakewood during the National season, but it's definitely a power loss. Even the 450 guys feel it.
