Made my KDX street legal in VT and enjoy going to bike night on it more than i can describe.
Mix is right, or fairly close, always had 4 strokes before, but... oil every where even on jacket. beautiful black stuff dripping out of pipe.
does not seem to be loading plug, any ideas?

What kind of oil do you use to mix ?

Excessive spooge is generally due to a rich condition. Check the jetting guide on this forum.

not necesarily (uh how do I spell this?) true, my bike is jetted a bit rich, no spooge at all.

The right two stroke oil is the answer in my opinion.
Putoline MX5/MX7
Castrol TTS/TTX
these are the 2 I mostly use.

Both are full syntetic oils and are designed to produce no/minimal carbon deposits, burns fully up.
Spooge is unburned oil.

What ratio Frysk? I mix the cheap SuperTech stuff from Walmart at 40:1 and get the same excess spooge on my back and fender at high speed. I know the oil is my problem.

spooge will be affected by the type of oil you run, temperature, humidity, the ratio you use and obviously: the jetting.
It is not just un burnt oil, it is un burnt fuel mix due to too rich of a condition.
you will get some spooge no matter what unless you could be spot on all the time under all temp, humidity and your altitude never changed... close to impossible imho.
if you are getting a lot of spooge all the time, one of your circuit is too rich (from what you describe, i'd guess the main is too fat).
I'd follow the jetting guide again and do a plug test.
My .02

I noticed that when I started using marine StaBil in every thank my spooge level decreased with no jetting changes. I attribute it to the anti ethanol properties. But yes, jetting and premix oil is the main cause of spooge.

I would stop using that walmart oil and go to a full synthetic. Also, even if you 'cured' your spooge problem you'll never know without repacking your silencer.

Yeah, I will. I hate having oil splatterd all over the back of my shirts. Going to pick up some 'smokeless', full synthetic this weekend. Then I will work on repacking the 22 year old silencer. I'm sure it is going to be real pretty in there.

be sure to get oil from a good brand..
And don't get Denicol oil, thats mineral oil and creates even more spooge.

I personally think a little bit of spooge is necessary, remember you want your power valve to be at least a little bit wet!

yet that doesn't mean that it should come out of the back end of your bike.

Depends, in the 80's it did. Now everybody wants to run 9999:1 fully synthetic ratios. There is a big difference between the odd drop here and there and pools of it though

The reason for that is that oil and gasoline nowadays are of higher quality (especialy the oil)

I run 1:40 full syntetic and not a drop of spooge at the back of my bike, but when I pulled my cilinder apart the kips was greasy.
