I was told to use a 32 to 1 mix by a bike mechanic
32:1 is a good ratio.
32:1 ratio
20:1
40 to 1
The oil to gas ratio for a Suzuki DR 80 would be 1:32. This means that for every gallon of gas that is added, 4 oz. of oil must be added as well.
135ml to 5 litres of petrol.
MANUAL SAYS 20:1
50 to 1 2.6 oz oil to 1 gal gas
IT IS 50 PARTS gas 1 part oil so 1 pint of oil for 6 gallons of gas
Forhonda says 20:1. People run 32:1 and synthetic for less plug fouling
if it is not oil injected rule of thumb is 50 to 1 ratio.
The manual say 20w40 but I use 10w40 normal motor oil with any trouble.
