Manx racer Cal Cooper still leads the British 450 Championship despite a few set-up issues at the latest round at Mallory Park.
Riding for JDF Racing, the tall 15 year-old finished in the top six in all four races with a highest place of third - he won all the contests at Donnington Park at the previous meeting.
The rider from St. Jude's had to cope with mixed conditions with the morning session dry but it was very wet for the afternoon with occasional hail adding to the difficulties.
