Whats the fuel mixture ratio on 1982 Honda 250r atc?

I ride a 1982 250R and I mix my fuel at 20 to 1 and havent had a problem yet and been riding it for over a year!

It also depends on what oil you are running. I run AMS Oil and it calls for a 50:1 mix. Just make sure you read the directions on you bottle of oil.

Never use 50:1 Klotz Synthetic Oil(piston blow-by+crank bearing destruction). Unless you want to rebuild every season....

Use 32:1
