If you are going to race a mini sprint there--check what size engines you can use-Last year it was a 600 only race--not a 610-640--race--Just to let you know

Oh look no 600 rules on the Butler web site again. Please Mr. Race Promoter post all the rules on the Butler web site. Or tell everyone where they can read all the final rules online.
