David Knight failed to win for only the second time in this season's GNCC series yesterday in Somme-like conditions at the Wiseco John Penton in Millfield, Ohio.
He even missed out on a podium finish in what proved to be a rare off day for the Ballaugh rider, coming home fourth.
Knighter's bike was slowed after taking a lot of mud and water into its air filter, requiring a pit-stop to get a replacement..
At one point he climbed to second and looked ready to challenge Suzuki's Josh Strang for second, until his machine stalled.
The race was won by Strang's teammate Paul Whibley, with Jimmy Jarrett completing a podium clean sweep for Suzuki.
The series continues in two weeks with the Weekend Warrior Spartan GNCC in Sparta, Kentucky.
