Hi & welcome
Cant be much help with the jet sizes , sometimes its trial & error , as you suggest start on the high side & work down if needs be .
You can buy jets from norbos shop on here I should think or dare I say it yam bits .

Interesting challange all the same , the very best of luck & be sure to update us with some pics of the event ,

Thanks Delbert really what i would like to know is a safe setup on the carb, I would be gutted to have it melt during the run.... i will most certainly post updates during the Run, I have the timing set but as I`m not familiar with the Rd any advice will be greatly appreciated
