oil spooge on my cr125. check this out.

[briere_06]

okay, i have posted threads on here before about the oil spraying out of my tial pipe when i run my bike. i went with what the feed back said, i played with my jetting and fuel/oil mixture. nothing worked. i got to a dealer ship and the dude says it is probably a crankshaft seal that needs replacing. has anyone ever heard of this seal causing spooge through the exhaust system or has it ever happened to you?

Yessir, if your right side crank seal goes it can/will let tranny juice into your bottom end, thus causing a rich condition and/or excessive spooge. Have you noticed any fluctuation in the amount of transmission fluid in your bike when changing it? Is the exhaust smoke very thick? Your always gonna have "some" smoke but is it excessive? What are you running in your transmission? It'll be very noticeable especially if your running ATF.

sweet dude, i havent been "Checking" my tranny oil often because i dont know how you do that, a just replace it very regularily. i guess i could find how much oil i am losing by finding the difference of the oil i drain out from what i put in it.....one question though, how will the type of oil make a difference in the oil dripping out of my silencer when i ride?
p.s. it does smoke but not excessively after it warms up, but litterally i have liquid oil coming out of the tail pipe as if someone was shooting it out with a water gun.

Theres basically two methods you can use to ensure your putting the correct amount of fluid in your trans. Measure fluid before hand and dump in, or remove your "oil check bolt" while your bike is level on a stand and dump in oil untill it flows from your "oil check bolt hole".

If oil was flowing from the check hole when you did your last change & you removed the bolt after a ride and there was no flow it "could" indicate a loss of fluid.
The oil check bolt is usually a 10mm bolt with a copper washer behind it, directly below your water pump cover(not to be confused with you "coolant check bolt" located on the water pump cover itself.

The type of "oil" you use in your transmission wont make a difference in how much oil is dripping from your silencer, BUT if you had a leaking clutch side crank seal and were running ATF in your trans the color of your exhaust smoke would be a very thick white-ish color, and could perhaps indicate that your seal was in fact leaking.

Are you exaggerating at all when you say "i have liquid oil coming out of the tail pipe as if someone was shooting it out with a water gun"? Or is there literally a constant stream of spooge shooting out? Some spooge is normal, but on a properly jetted 2stroke it should be minimal.

thanks for the walkthrough on that...no i am not joking about the oil spray, when i star the bike and put my hand at the end of the tail pipe and give it a good rev, my hand is totally black with spooge, from one crack of the throttle..its bad, my and my bro went riding and when we got home his front fender and # plate were spattered with oil from my bike.


......help please.......

Np man

Couple questions...

-How does the bike run? (when you crack the throttle do you have good response?) ie : any bogging or sputtering?

-Does it idle?

-Start it with choke on or off?

-Pre-mix ratio? 32:1 , 40:1 etc...

-When you say you "adjusted jetting & fuel/oil mixture", do you mean you actually changed jetting, changed your pre-mix ratio or just played with the air screw?

[briere_06]

yes, thi bike idles and starts with choke on or off first kick, its still a honda! it sounds good, a bit quieter then some 125 bikes , sounds like it cant breathe cause of all the spooge backed up in the exhaust system though. no real bogging or sputtering to be detected. pre mix at about 45:1 using amsoil dominator synthetic race oil. when i say "adjusted jetting & fuel/oil mixture", i mean that i leaned out my fuel from 35:1 to 45:1, and as far as jetting goes i moved the needle clip two positions leaner and one step leaner on the main jet. i noticed a good power gain, i simply mean i set up the jetting for my altitudes and weather conditions. but no progress with the crazy amount of spooge i was getting. ....what exactly does playing with my air screw do?

We'll you say it idles but at the end of the paragraph you say "what exactly does playing with my air screw do?", so for the sake of conversation ill assume your adjusting idle with your throttle stop/slide stop screw. It just pushes your slide up in the carb giving you more of less fuel to engine. If your pilot is crazy rich and wont idle right you can compensate with said screw. Its not a true idle though you just basically bypassing your idle circuit.

Your airscrew meters the amount of oxygen in your mixture, turn clockwise to richen mixture(lower idle) and counter-clockwise to raise idle. Turning it in or clockwise leaves less oxygen in your mixture, effectively richening. Theres an awesome jetting guide around here somewhere , either faded's or spanky's... goood stuff you should check it out.

"i mean that i leaned out my fuel from 35:1 to 45:1" There alot of people around here that would tell you to never run less than 32:1 with your premix in an 80 or 125 etc. Those suckers wind their brains out and usually need more lubrication. I myself dont have a ton of experience with 125's but in my kx125 i never ran less that 32:1.

When you changed your ratio you actually made your mixture richer. 40:1 is richer than 32:1. Im still not completely sure if it isnt a rich condition, namely on the pilot.Its really hard to say without the bike sitting in front of you, you know?

If your silencer isnt saturated and dripping with spooge or your exhaust valve full of spooge contributing to the drippage.... Maybe it is the seal. How long has it been since since shes had a new top end? how many hours you got on her atm?

Anybody else wanna jump in here lol??

[briere_06]

k well i never did anything with the idle because it idles like new and always has since i got it. my friends dad knows his way around a 125 and says it has got to be that clutch side seal on the bottom end, allowing the oil to burn away, today i rode my bros yz250, i noticed way less smoke and his smoke was a lot less dark than mine and he has no spooge. i know how to jet trust me i have read many how to's and i did it properly. 20 hrs on the new top end from last year. but i dont get how less oil in your premix makes it "richer" as you said. please explain that one to me. but anyways i am really thinking its that seal because even with it not jetted properly it should not spooge as much as it does, seriously its rediculous. i am thinking i will probably start mixing at 35:1 and go ahead and buy that bottom end seal kit.

[ClosedCasket]

A higher percentage of your fuel mix is now gas @ 45:1 as opposed to 35:1. The amount of fuel in the mix determines its "richness" , not the oil. All the oil does is lubricate and displace a tad bit of fuel from the mix. You put more oil in your mixture @ 35:1 therefore its a leaner mix.

Lets say for the sake of conversation that every sip of dino juice your bike takes in @ 35:1 its getting 90% fuel and 10%oil(premix). When you change your ratio to 45:1 the engine is now getting 95% fuel and 5%oil(premix) , the engine is now running richer because its getting more fuel and lesser oil than @ 35:1

Best i can splain it

[briere_06]

okay that makes sense. so back to the origin of this thread, you have seen those seals break and cause spooge? bacause that has got to be it. and just wondering how a go about tearing that bottom and up because i have never been down there, ive only worked with the top end. and just out of curiosity, what would make the seal go in a bike that has only about 2 seasons on it?

Theres many documented accounts ive come across on the forums but its only happened to me once over the years and the bike ran like Sh1t and yes spooged like crazy(the ignition side is more common and has gone out on me a few times though ).

There isnt any case splitting involved so its pretty straight forward... Remove right crank case cover, remove clutch, remove primary drive gear, remove old seal and slap the new one in.

I havent a clue as to what would make one go out on ya besides just regular wear. You say only 2 seasons but unless you only took the bike out 10 mins a day person, 2 seasons is quite a long time when yer talking about seals on 2strokes etc, at least IMHO. While ive only had one go south on me , ive never left them get to any point that one might fail. Not that im saying yours went out for lack of maintenance , im just paranoid and change crank seals , piston & rings about every 40 hrs. Im sure i could go longer in between, im just a big fan of preventative maintenance

[briere_06]

hey thanks for all the help. i do as much maintanence as possible with my budjet which is only $100-$200 once i pay the bills and all of that stuff. i thought i would have to split the cases, but say i buy a complete bottom end bearing and seal kit, then would i have to split it to replace the rest of the stuff?

Np at all

You wouldnt have to split them to replace the seals. You would have to split the crank cases to replace the crank bearings but its no big deal, theres lots of threads around here case splitting/rebuilding bottom ends etc.

[briere_06]

right on, i am gonna do that, hey even if that doesnt help the spooge, it never hurts to replace seals and bearings in the bottom end!!!

Awesome, lets us know how it turns out and dont forget the pics

[briere_06]

suonds good man, will do

[southy]

i have the same problem mine, it is leaking down the pipe
it is also leaking out of the seams at the front
i over filled it so i droped the oil and redid it but it just wont stop leaking
i have lowered the oil level in my fuel
if you have any suggestions

[chud]

Start a new thread, and include more detail, such as: Yr. of the bike and maintenance history.

Lowering the oil in your fuel will not cure rich jetting or bad seals.
