Greetings all,

This is my second post after my 'hello world' post :grin2:

I just got my 2017 Grizzly, and I was giving it a thorough look over. I am a little puzzled about thick clear blue liquid I found in the airfilter box. It is on the back top side (towards the rear) and there is a little standing in the back bottom of the air filter box.

It has no smell to it and is pretty thick. I do not recognize the color or or thickness from other common engine fluids.

Anybody have any idea what it could be?

Thanks,

WanderAlaska.

Excess air filter oil, mine had the same thing... I've seen other posts here on that subject.

More then likely air filter oil. It often blue, thick and very sticky. A properly oiled foam air filter gives you maximum protection against dust and other contaminates from entering your engine.

It is what I was suspecting. But it looked very thick to me.

But I am comparing it to a K&N air filter recharge which is quite opposite :)

Thanks all for the quick response. I hate to have to call the dealer for a repair this early into having the ATV :)

I was used to the k & n filter oil too. This stuff is way thicker and sticker for sure!

K&N oil is for a paper filter which is much thinner than the oil for a foam filter.

I may be 3+ years too late. But I have a 2019 Grizzly 700 SE and it ha a the exact same problem.
but I noticed under the air box, where that blue thick liquid is at, there’s a clear tube holding the liquid. It looks like it was meant to catch or hold some of the liquid there.
Anyways did you find out what was going on or if it was normal?
Here’s a pic , the tube is on the middle right held by a metal ring , furthest from the picture.

Welcome from Colorado.
Your picture is poor, try following the tube to the other end. Does it connect to the engine?
We use thick oil on the filter, and some can run off.

Hey, greetings from Texas.
It’s connected to the air box where the air filter is at. Basically that is under where the concentration of the blue liquid is located in my air box when I open it up. I’m guessing that’s how it looks on these newer model grizzlys.

The other end is blocked off?

That is a plug for the drain hole which is there to drain water out if water gets into the air box. The blue oil is air filter oil that Yamaha uses from the factory and they use way too much. Which is why it ran off of the filter and onto the bottom of the air box

I hope they just used too much of it and nothing goes wrong. I’ll keep a close eye on it and re clean and oil the filter myself. I’ll see if this problem still occurs or not. I’ll keep you other Yamaha owners updated.

Older bikes have a hose from the air box to the case for ventilation, didn't know about the newer bikes so asked.
Most here knw its better to add too much oil to the filter and some drip off in the box than to add too little and let fine dirt get into the engine.
Mom?

It should be somewhat clear too so you can glance at it to see if it has any water or dirt therefore needing maintenance. You will probably need to remove it and give it a good cleaning until it's clean/clear.

Your worrying about it too much. As previously stated yamaha really goops the shit out of the filters at the factory, its fine. I had a puddle in mine that I wiped out after I cleaned the filter when it got filthy.

did you also drain it?
Mine didn't have as much as yours does, I only had a little puddle under the filter.. but it won't hurt your machine to get whatever oil is in the tube out of it.

How full is the tube exactly?

It was all full. My puddle was all in the back side where the drain plug is at so of course it filled the tube.
Just cleaned everything and yes I can confirm it is the Air filter that is very oily. I pressed it against my hands and almost a teaspoon came out on one end of the filter.
