Best ratio of racing gas to unleaded pump gas

[KDX1]

I bought some Sunoco 115 octane race gas and was wondering what is the best ratio to mix it with regular unleaded pump gas. The motor is stock. Will I have to adjust my jetting? Thanks:think

Re: Sunoco purple

Yes, Rich it is in fact purple. I went to Sunoco's web site and was able to find some information regarding the specs, but I don't know at what ratio to mix/cut it with regular unleaded fuel. Any help you could give would be greatly appreciated.
Thanks :D
