Noticed a drop of oil last weekend while out with MarkCBXX and slvr(Roy). Lots of ideas on the causes, but I believe it is the oil being pushed through the wiring insulation. This could very easily go unnoticed if it does not drip. What I would like for you guys to do is check your 12's and see if you have an oily residue in this spot. Even on my 02, with only 1900 miles there is a oily film. Sitting at the back of the bike, just behind and above the passenger peg on the left side, you can pull down on the plastic and expose this area. Go check your bikes, you will need a flashlight, and let me know what you find.
Here's the pics of where to look........

If I was a gambling man I would bet my 12 on it MW. Just seal it off before your connectors have a short or it will be a mess like mine was.

Hey MWR, could you put an arrow in there? I think I know where you are talking, but don't want to make a false assumption on this one.

comes from the stator. The wiring harness is not sealed off from the oil it's in and can follow it right up to the connectors. The 12 makes quite a bit of positive crank case preasure. The oil then gets onto the conectors and causes a short and eventualy will melt and cause a voltage regulator malfunction.

This all happened to me last year.

& that makes me wonder..could this problem be caused by too much oil in the crankcase? I'm kinda picky about the amount of oil in my ride & never over fill it.

Just a theory



& if it's the CrankCase pressure? Then that's one more reason to do the CrankCase mod. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)">

Blitz, the foam piece I am pulling down on fits around a round connector, I am guessing to prevent vibration, but it is that connector and the wires leading from it with the oil residue.

I did not have time to disassemble it tonight, but I will check it out on Saturday. You can see in the second pic to the right of my hand is where it seeped down and let a drop fall on the chain guard. If not for that one drop that fell I probally still would not know this was going on.



Green Mamba, I changed the oil and filter about 200 miles ago, I always change the filter when changing the oil. I always let it drain completely and put in 3 qts. It is 2/3 up on the sight window, which is perfect....

Well then, you've got the oil bases covered.

Think ya might try the CC mod?

before ya silicone the stator wiring.

Mark,



I just went out and FELT the ass end up....

And it was dry as a bone....Are you thinking the stator has oil in it that is leaking ?????

I dont know im just guessing..give Doug a call tomorrow maybe hell have an idea....



See Ya,

Slvr!

I'll check mine tonight. Hey Roy, my thoughts exactly about wheelies. They may have sometime to do with it. When folks respond, let's fess up to wheelies or not.

Green Mamba - I did not have any plans to do the crankcase mod, but that does not mean I will not sometime later on...



I rode in to work this morning. It is not leaking as you may think. Just a light film like the picture shows. I don't believe it would use any oil, but it very well could cause problems with the connections as previously stated......



I doubt wheelies would cause this, but I do sometimes let the engine slow the bike when riding hard, which I think may build a lot of pressure....Just throwing ideas around.....



Even though I'm under warranty, I'd rather fix it myself than take it to a dealer...

Here's the deal...when mine happened, I assumed it was from wheelies. How else could it get that high up the wires.... but when I dropped the bike off to get all the probs fixed, my mechanic was already aware of the problem. Said he heard someone talking about it at a tech class he went to.

He said wheelies would speed the transfer of oil but would eventualy end up at the connector anyways. He described to me just how much preasure that crankcase makes in the 12. No PCV mod would cure it but it wouldn't hurt.

I know this guy is a good mechanic, but I also know they can bullshit their way through anything. I just had him go ahead and fix the problem with silicon. He even went a step further and put the kind that is fuel/oil proof. Other wise...regular silicon would break down after a short time. He also replaced the whole wiring harness, stator, and voltage regulator.

what about cutting the insulation on the wire as a temporaray fix so that it wont seep all the way up ????

Hmmmmmmmm?? be better to keep the oil where it belongs, just don't know how much of a job pulling the stator cover off.

actually I was trying to edit my half brain response...lol.....If you fill the wire insulation with silicone you then "cap off the leak".....My concern is the silicone working its way lose in your engine case and then ultimately clogging up something else......Who Knows if oil can get in connectors on this machine....anything is possible.......Brian

If this is that big an issue -- might be something Kawasaki shoul be handling as a recall or under warranty. This is the type of things that you have no control over and it could easily leave you stranded.



I hope there is no fire risk here? Oil and electricity? not likely but any opinions are welcome?

About the oil and fire/electrical.....damn right it can burn and burn quick. My bike was real close to catching on fire. After looking at the wiring harness and connectors, I don't know why the bike didn't burn to the ground.

I wondered what the hell that crap was. Had that stuff smokin once, (coming from underneath the seat).



Only way I could pull the connectors apart was with a knife.



Smells like wet cigarette butts.



So guess it aint chain lube.
