[lemmy]

I would think needle you are using would be something else of importance.

[josefmd]

Year of bike = 2006
Main jet =152
Pilot =42
Clip position =2
Mix =32:1
Altitude = 1000
Temp = varies from 40's in fall/near winter, 80's to 90's summer
Mods = Snorkle removed, FMF rev pipe, TC powecore 2 silencer. BR7ES plug.
Other = I still get spooge. Have tried a crap load of combos, going richer on pilot/leaner on clip, etc. I have basically given up tweaking this thing. I have also checked reed's, float height, repacked silencer, etc, and I am still smoking too much and getting spooge.

 

[lemmy]

Have you thought about going to something like 44:1 on your mix?

 

[josefmd]

You mean go to 44:1 and effectively make it worse by making to circuit richer. Less oil means more fuel=richer jetting. From all I have learned from a lot of threads with regards to this subject, it's better to stick with whats recommened 32:1 and jet for that. The common method is going to something like 50:1 will cure plug fouling or excessive spooge/smoke, it dosen't, it makes it worse.

 

[aussie smoker]

Year of bike = 2000
Main=162
pilot= 48
Needle clip= second from top
Mix 40:1
Altitude = sea to 500 ft
Temp hot above 10 degrees c
Mods = Pro circuit platinum 2 / snorkel removed.
Have tried many combos with jetting and found current set up suits me best .
Still get spooge / smoke , even with a fresh top end approx 1.5 hrs old.
I was told by a dirt bike expert to run 50:1 but cant get my head around that.
His theory was that fully synthetic oils of today such as Motul 800T are far better lubricating than those of say 10 years ago .
Also a richer fuel mix will burn most oil creating less smoke and spooge .

 

[mudpack]

Spooge and smoke comes from burning oil, not from burning gasoline. You can reduce both by going to premium synthetics at 50:1.
That is...if your heart can take it.

Two-strokes engines will ALWAYS have some smoke and oil residue in the exhaust; there is no way to get around it. These are not four-strokes.

 

[zeerx]

I run 64:1 Golden Spectro Concentrate with 110 race gas. If I get it exact there's no splooge. Put in a tiny bit more oil and the splooge is back. Smoke it there reguardless. KDX220. YMMV. Cheers.

yeah, i know that less oil makes the bike richer, but I assume you would know that you would have to adjust for that with the jetting.

so you think spooge and plug fouling is caused by the bike running rich (by rich I mean too much fuel, I am not meaning too much oil)?

 

[Sandman 2.0]

Year of bike = 2001
Mix = 32:1 Yamalube 2R
Main jet = 155
Pilot = 45
Clip position = 2nd from top
Mix = 1 1/2 out
Altitude = about 900'
Temp = 40°-80° plus
Mods = Air box lid opened, no snorkle. Just enough left to hold the electronic gizmo/Ready racing air filter
Other = Bike still smokes some. I tried 152/42 combination but had bad bog off idle. Mix screw had to be less than 1 turn out to get rid of it. Went back to richer jetting. Bike runs great. I'd rather err on the rich side.

Yes, it can be.

Mud pack im with you on the smoke, but spooge would indicate not all oil is burning ??

My son has a YZ 125 2000 model and I also ride with mates on Kato EXC'S . My KDX blows enough smoke for all of them .
They do not smoke any where near the KDX and I have new piston and rings .
I guess its just a KDX thing ..

 

[Sandman 2.0]

I guess its just a KDX thing ..[/QUOTE]

I think it must be. My KDX runs great as jetted and my plug is tan. Not burning any tranny oil but it does smoke more than my KX and always has since new. I often wonder if its the stock silencer collecting oil. I was planning on changing to a FMF pipe and silencer over the winter so we'll see.

 

[lemmy]

I know that when I accidentally put my 32:1 lawnmower mix in my 64:1 weedeater, it smoked like crazy and it normally doesn't smoke at all. I guess it depends on the color of the smoke.

 

[mudpack]

True. Oil residue in the exhaust system is unburned lubricating oil. This is the oil that is in the fuel. Two-strokes are ALWAYS burning oil....that's how they are designed.

Four-strokes rely on good rings...correction: good oil scraper rings, (not the upper sealing rings) this is why two strokes do not have oil scrapers and four strokes do...to prevent crankcase oil from getting into the combustion chamber, being burnt, and producing exhaust oil smoke.
Two strokes produce exhaust smoke no matter what the condition of their rings, since the oil comes in with the fuel as per design.
NO two stroke will burn ALL of the oil in it's fuel mixture; oil just doesn't burn fast enough, and some of it will always go out with the exhaust gases. The richer you pre-mix...say 32:1 instead of 50:1... the more oil you'll get in the exhaust system. But a two-stroke will always have some oil coming out its exhaust.
Just to complicate our lives a little more: some oils will burn more completely than others. This is why some bikes that seem to smoke very little will have comparatively large amounts of spooge. And visa versa....

That's it for today's lesson. Bring your Kawasaki Factory Service Manuals to class tomorrow, we'll be looking at rear suspension geometries and how to set up damping rates to take advantage of the KDX's system. :rotfl:

Back from the archives,...
