well thats just stupid, this means I can run my YZ125D with Noguchi watercoolong kit in pre 78, but I can't run the Banzai Mugen in Evo , No wonder none of the trick bikes never make it to the track, too many scruitinazi's out there , and I certainly don't have the temprement to deal with them,...
No you can't run a water cooled bike in pre-78 - there's a rule in there that specifically prohibits water-cooled bikes.
Look, I've been (and remain) quite critical of the wording of the rules, but their intent is well supported among the punters: To get bikes out there racing, and keep those bikes representative of the bikes that were racing 'in the day'. The 'no water cooling' bit is simply designed to stop people adapting later model production bits and otherwise creating ultra-fast 'specials' that never existed in the day. This is historic racing, remember.
AFAIK, you're the first person to seriously want to build and race a bike that's been converted to water-cooling in the history of Australian VMX - so don't go sprouting off about scrutinazis or the idiocy of the rules, because its simply a new issue that needs to be addressed, and you sound like you're having a tantrum....
Based on the responses so far, its clear that most people are happy for a bike using period parts to be raced in the Evo class. So if you genuinely want to race the bike, then its up to you to put in a submission to the Historic Commission explaining what you want them to allow, and why they should allow it.
Yes its some work for you, and success is not assured, but if really is important for you to race this bike in the Evo class, then its a minor hassle - sure it'll take a few hours at the PC, but compared to the time you'll spend building the bike, I'm sure those few hours will be trivial....
Alternatively, you'd be more than welcome at ANY race meet in the country to simply turn up and race with the pre-85 bikes. And if you're not chasing throphies, then there's no bad point for you.
