Gas to oil ratio

[gojo41]

I have 3 old enduros from the mid 1970's suzuki 185 and 250 ,kawasaki 175, all 2 strokes and they all have a seperate tank for injection oil , I was told to forget the oil tank and premix my fuel,, what ratio should I use????

I would say it depends on what kind of oil, how much wear and tear are on the motors. I run 50:1 Castor 927, but I would probably go a little richer on those dinosaurs. :)

i run 40:1, with bel-ray MC-1. most bikes recommend 32:1, but it depends on the oil you use. MC-1 recommends 50:1 with their product, so i just went with a happy medium.
