From what i remember tassie nats had 100 riders and 150 bikes but that was last year so my memory fades
, the whole bike scruit went through in 1 maybe 2 hours didnt it ? was prity easy and clean sailing based on odds or even i think. so dont worry about the calculations youl be able to eat youor lunch.
As far as Tony Cavell's Beeza went your right the protester just got outgunned by a class rider, cause he didnt just smash the field on the 250 but on all the other classes and bikes he rode in. should have saved his hard earned but it was his right to pay up and roll the dice to ask the question - makes the sport fair and transparent to do so.
I was with Tony when someone handed over the $70 and what they did to test it was clever in that the dispute was capacity based, so all the smart testiing guy had to do was fill up a can with 250cc of oil and poor it in the spark plug if he could see it, it was under and it was so all that needed was for tony to drain out the the oil, no gaskets, no strip downs, no cost to him. Only the inconvienice that he still had 2 rides to go in the next half hour with out a rest.
I thought the testing was handled very cleverly and very professionally i must say, it was fast painless and done in a very simple and painless way that both parties where happy with the outcome.
As far as the name on the jersey thing goes i had both names on mine and numbers and i reckon i was one of about 10 guys in the hundred that did, so i dont think youll have any problems, if in doubt put your number on it at least, but dont do it till your number is excepted incase someone else gets it first and you have to change ( hey pete 52 )
If Dave tanner is doing the eligibility he knows what is right or wrong so dont try and slide stuff in tot he wrong era other wise you will get pulled up, do the right thing and you will sail through, be sure you bike has no missing spokes, throttle that returns and any obvious saftey things, like sprocket covers, unless your 100% youll be running 1-4, you'll just, get do your head in with stuff that in the end wont make a differance to you enjoying the NAtionals, if i can pull a ride up there this year ill be winging it , get the basics done to the bike, everything else can be fixed on the day IF its a problem.
you cant plan for all things or all drongos, but i think the majority of vmx'ers would just be glad you turned up and just rode in the right class, the rest as i said is the small stuff, so dont sweat it.
