Thats great info Robert.
But every series may have there own take on the rules. Club racing 99% of the time wont require you to have all the updates.
Plus most club series will say they follow Rotax rules. But the true fact is at club level they want entries and wont be anal cause you have an older cylinder and other non updated parts.
Tony has it right check with your local track your racing at and see what they say.
