Hey how do i do this...........help?

Question

How do i know what what oil mix to put in a kx250

Answer 1

THIRTY-TWO:ONE IS OWNERS MANUAL RECOMMENDATION

BUT...There are many factors that can change your need for this ratio.  

In my KX250, I used Elf Synthetic Oil with 108 octane gas, sometimes 93 octane when I couldn't run 108.  

Either grade I mixed at FIFTY:ONE.  

Because of a few reasons I used this ratio.  

1)I had a Vforce reed cage and reeds that allowed the motor to breath differently.(the reeds somehow fluttered better, mixing gas and air more effectively?..?)

2)I changed my main jet to, I believe, ONE size larger...It has been few years...but I am almost positive.

3)Also, I ran pro circuit pipe/silencer

4)The elevation and temp you live/ride at also determines the mixture/jetting needed

This may sound kind of difficult or confusing if you do not have a few years of mix'n gas every week...but, it really isn't all that critical to be exact.  

(basically you want to get bike to optimum performance by NOT having medium or heavy exhaust smoke...light smoke almost none when warmed up)

Play it safe using 32:1 with new top-end,(half gallon or so)then lean it out to 50:1....after riding for an hour, check your plug for a whitish/grayish powder tip or a wet/oily tip...neither are good!

If I was you, I would go to kawasaki online and I am pretty sure you can download an owners manual.  Read it over and over till you are sick of it.  (I used to when I was young)

Good Luck and Keep Riding!
