kx85 i need some help

[03kx85]

i have an '03 kx85 and it runs alright but when i ride, oil comes out the pipe and drips down the outside of the pipe. it gets all over the engine and the airbox and makes a mess. i use a 32:1 ratio in the gas and measure it perfectly.WHAT IS WRONG

too much oil in the gas. the motor isnt burning it go leaner in your mix.

WRONG!
It is caused by rich jetting, not your pre-mix ratio. Reducing the amount of oil will make the air fuel ratio richer, and only make the problem worse.

Try leaning out the jetting a little bit. Most of the KX85's benefit from leaning the needle one positon too.

I think we have the same problem with Grant's 95' kx80. How do you lean it "one position"?

Thanks! We have a service manual on its way....will it be in there?

Move the needle clip up one position, this drops the needle and leans it out.

I have not jetted any of the older KX80's only the KX85's and 100's so I do not really have any good jetting set-ups for you to try.

Most of these little KX's like to drool, I don't know why the Yamaha's and Honda's can be jetted pretty clean, but the little KX's always have a little bit of drool. I have leaned our bikes to the point that they were boggy and too lean to ride, and they still drooled even with new packing in the muffler. So I just jet them where they run good and the plug looks good. We have never fouled a plug after several years of running these bikes, but we always have a small amount of drool, nothing bad, but a small amount none the less.
