ASTWOOD Bank's Andy Tinsley says he is gunning for National Superstocks Championship leader David Jefferies at Knockhill.

Tinsley heads north of the border at the weekend hoping to continue his impressive start to the season.

And he wants to take the scalp of the only rider in this year's series he has yet to beat.

The Buildbase/Knotts rider is fourth on the leaderboard ahead of the Scottish round.

Redditch-based rivals Legs 11 will again be represented by Kelvin Reilly and Gary May.
