I have 00 rancher it says to drain the air filter box by pulling the Plastic window cap.
I pulled the cap and all this (motor oil type thickness) liquid stuff came out. Took the lid off and the filter looked ok but all that crud at the bottom.
Is this normal i pulled the filter and the bottom of the box had all this liquid stuff.
Is that normal I bought the quad used so I dont know how they are from the factory..
It was not primarly composed of water I dont think seemed to thick.

thanks

 

What I heard is that later model Ranchers have a baffle that the older ones don't have, to prevent oil from splashing and ending up in the crankcase vent (that slot underneath your air filter). Not sure if it is true???

My Rancher is also an 00, and at times in the past I have had lots of oil in my airbox. But strangely, I haven't had any in a couple of years. I think it is a common occurance especially if you ride fast through very rough terrain or if you happen to overfill your oil.

 

Ok, thanks I was kinda worried that i had a big problem but I better keep an eye on the oil.

 

The way more likely culprit to your problem is the last guy over oiled the air filter so the excess eventually drips down into the box then mixes with dust to form the nice crud you mention. I am super guilty of using too much oil in the filter and not getting the excess out. It ends up exactly as you describe.

I have got a 2005 Foreman ES with only 300 miles on it, and i have noticed a liquid in that clear cap underneath the airbox, drained it and thought nothing of it. Any ideas on what it might be?

 

Like quad2xtreme said....."air filter oil"

 

yeah it's most likely air filter oil. I sometimes over oil my filter and the excess will drip to the bottom of the airbox and collect crud. nothing to worry about, just more sticky stuff to grab excess dirt from going into your engine [img]i/expressions/face-icon-small-tongue.gif[/img]

 

No way mine was air filter oil. I use Maxima FFT on my filter, and after that stuff tacks up (after the solvent evaporates) this stuff is so thick that it isn't going anywhere. What I had was engine oil, and plenty of it. Like 1/4" sloshing around in the bottom of the airbox. I could see where it come up from the breather, and the piece of foam in the breather was completely soaked with oil (even though it is under negative pressure).

It is something that just happens sometimes.

 

If the quad has been upsidedown of in certain positions on its side you will get motor oil in your airbox.

 

Honda put out a notice to its dealers on 350 Ranchers w/ oil in the air box. The most common cause of this is the rider will start up the machine and take off immediately. The rancher has a dry sump motor, and when the machine is started and not allowed to idle, oil will be forced thru the crankcase breather which is on the right side of the motor. If I can find it when I get to work tomorrow, I'll have to post it so you all can see it.
