    We used 25 : 1 back in the day but with modern oils i would think 50:1 would be fine. Most of the 2 strokes of the day run on 50:1 with modern oils with no problems at all. Will have to be your decision though as i take no responsibility for your motor if you follow my suggestion.

    I agree with otf - the bikes I have which ran 25:1 or 32:1 back in the 70s/80s as your Sachs did are fine on 50:1 with modern two stroke oils.
