Hydrex Honda team boss Shaun Muir has said Karl Harris must re-find the focus he began the year with in order to get back in the fight for podiums and wins.

Harris, who went to the Knockhill BSB round suffering with a bout of food poisoning, crashed out in the first race on lap one and was forced out of race two when his chain jumped off.

"Karl's food poisoning affected his performance all weekend although he dug deep in qualifying to end up fifth. He’s still lacking a bit in confidence though and needs to improve his race craft slightly as he’s finding himself in positions that he shouldn’t be in," said Muir.

"It was his own mistake in the first race and then in the second he got stuck a bit in no man’s land down in seventh when the chain jumped off. He needs to get his focus back and try that little bit harder and if he can do that I’m sure he’ll be back to where he was at the beginning of the year.”
