The owners manual calls for 20:1, however with the improvement in 2 stroke oils since 1980 a 32:1 to 40:1 should be fine.
the mixtuer is 40:1 I like to use a 32:1
mix fuel honda atc 200x 1984
air/fuel ratio problems p1259 Honda civic/Honda accord
The factory owners manual recommends 20:1 fuel to oil ratio.
17.
20:1 is what honda states
Every 2 stroke Honda that I have had is 20 to 1.
32 to one
32:1
32-1
This ratio is 40:1.
Are you trying to go leaner or richer????
