1 gallon gas 4 ounces oil
800ml
near the oil filler somewhere on the cover it will say how much you need to put in
i use motul fully synthetic factory line 2 stroke oil in my kx 125.putting 25 ml to every litre.
I think 700 cc or .7 Liters
It tells you underneath the fill cap 0.65l
32:1 mix of a GOOD oil.
no the 1985 kx 125 cylinder will only fit years 85-87 kx 125s
There should be a Phillips Screw on the side by the kick start remove screw and fill until oil comes out
80/85 weight
Does it always bog? Maybe you overfilled the case with oil. Have you tried a new spark plug? maybe your in the wrong gear. -need more info on what it does/when it does bog-
you want to be putting 25ml to every litre of fuel. ie 125ml to 5 litre .
