premix ratio for a cr85

just bought a cr 85, but dont know what the mix ratio is..... can anybody tell me what it is?

Depends how your bike is jetted. i have to run 40:1 in my 125 or i will foul a plug in 10 minutes lol, my bike is jetted so rich. since the 85 depends on really high rpms to make power i would run 32:1.
