i use motul fully synthetic factory line 2 stroke oil in my kx 125.
putting 25 ml to every litre.
you can use a lot of different oils, I use ams oil 10w40 in my kx 250, almost all wet clutch transmissions can use normal 10w40 motor oil. as for the crank, it is lubricated by the oil in your gas.
SAE 10w30. I recommend you use synthetic in this air cooled engine.
32:1 mix of a GOOD oil.
no the 1985 kx 125 cylinder will only fit years 85-87 kx 125s
1 gallon gas 4 ounces oil
80/85 weight
In the crankcase your looking for 10W40 or any gear case oil from you local 2 stroke motorcycle store. I use 80W Racing oil. If your talking about the fuel then you need 2 stroke mix oil with your gas and that ration I would suggest would be 32:1
no i have a 2000 yz 125 and can beat a kx 125 blind folded
Yes
my 87 kx 80 bigwheel has the same problem. it needs a new water pump gaskett
the difference is that a kx is a 2 stroke bike and a klx is a four stroke. the difference in strokes is the cylinders and a 2 stroke needs gas mixed with the oil
The seat height on a 1991 kx 125 is 37.1 inches
