At a national event alot of the time is spent ensuring bike's meet eligibility critera ie. numbers/backgrounds, suspension travel, numbers of back, ensuring bike meets cut off date, noise testing things like that.
General consensus is that if you turn up to race for a National title that you won't have loose spokes
When was the last time you saw Craig Anderson's bike having it's spokes rattled by some bloke in a flannie with a screw driver in his hand.
You will need your name and number on your back
Don't forget to put the letter infront of your race number
bike meets 89 db noise test
bike complies with period........if oyou want to argue make sure you can back it up with proof.
correct number plate background colour.
Ensure you have all your paper work done, that includes one day licences done before the event not on the day. That may include competence testing.
