I think you need to look on Scottishmotocross.co.uk
As Tootall on there just spent a couple of grand of his own money, machines and time to get the track back to good condition. The track is going to be looked after a bit more, unfortunately it has been run down to due the Irvine Motocross Club not running events there and doing the major rebuilding/grading of the track. Hopefully next year that will change and the track will get its jumps etc graded more rugularly.
If you want a good graded track then drive to Doune/Dunblane.
