There is no fuel mix needed they are 4 stroke air cooled. Just use straight gas. dbg
it depends really i have the same bike and i do 40:1 ratio that's 16oz to every 5gal of gas
The 250 uses straight gasoline.
20:1
50:1
50:1 ratio
VERY likely your fuel mix is too lean. Adjust the air/fuel mix settings and it should fix it.
2% fullsuntetic oil
switch up the air fuel mix on the carb or maby the spark plug is bad
for my 1982 Cr125 the gas mixture is 40:1... not positive if its the same for a 250... but my suzuki 1991 suzuki 250 is also 40:1 so its most likely 40:1...
i use 927 mixing oil and i put 4 ounces to the gallon. : )
