Fuel Mixture

[Tez_Mitch]

Hey all. New to this. Could someone out there please help me with the correct fuel/oil mixture for an 84 QR50. 25:1 or 40:1 etc. Thanks in advance.

Most likely 25:1 all the small 2 strokes i have jumped on use 25:1. Google it see what comes up.

i have a little 50 and i use 20:1 it works fine.
5 litres of petrol:200 ml's of 2 stroke oil.

I did google and nothing came up. As for the responses so far, while appreciated, I am not after guesses. Four responses and three different ratios so far. Someone out there must have one of these and know what the correct manufacturers ratio is? Thx.

I had a QR50 and I used 40:1, but used about 30:1 if I was in sand or mud so the motor stayed a little bit cooler when it had to work hard.
It worked fine for years...
