Proper Technique for Oiling Uni Air Filter

harfooz · May 20, 2011

Hi folks,

What is the proper technique for oiling the Uni air filter for the Gen I FJR? I bought the filter and a bottle of the oil. The instructions say to put the oil on it and squeeze it out -- but the foam filter is behind the mesh cage and I can't really get my hand in there to squeeze it out completely. I'm concerned that there is still too much oil on the foam. What I did was pour the oil into the inside of the filter. Let it soak in and then try to squeeze as much as I could out with my fingers pushing the oil from the inside out. It was just about a mess.

Am I doing this incorrectly?

Thanks,

Doesn't the filter come out of the mesh cage? https://www.unifilter.com/maintenance.html

I saw that too and thought that it should come out, but the one I have seems to be glued in place at the edges.

I've emailed the folks at Uni to find out if the inner foam element will come out of the mesh cage exterior and will let everybody know what I find out when the reply.

I got word back from Uni:

Hi Clint,

Yes... You will need to squeeze out most all of the oil.

Use paper towels to soak up the oil.

Would be best to use our Spray oil for your type filter.

UFF-100 spray oil

UFC-300 cleaner

Kit with both... UFM-400

When I went out to the garage on Sunday, there was about a half-teaspoon of excess Uni filter oil that dripped on the floor. Not so good.

Off comes the Tupperware (again) to mop out the filter with lots of paper towels.

Note to self and other folks: use the spray oil next time.

P.S. Free to a good home: open bottle of Uni Air Filter oil.

I have a Uni filter that was in my bike for a while. Now it's in a box on a shelf. Went back to the OEM filter. No more worries about too much oil mucking up my throttle bodies, or too much dirt passing through the filter. I can't dicsern any difference in the way the bike runs and I have piece of mind...I also have a useless to me Uni filter if anyone wants one cheap.

I'm glad to see I'm not the only one who is concerned with this Uni. The uncertainty of whether there is too much or too little oil, and possible engine damage is enough for me to see about ordering up a replacement OEM air filter.

I would think of any engine damage, due to over oiling, would be zero. The excess oil would just be sucked in and burned off; problems arise with vehicles that have wire-type mass airflow sensor getting coated with oil and rendering them inoperative.

You would thunk that, but you'd be wrong. That extra oil gets sucked over the throttle bodies and gums them up. It may have happened more, but I saw the pictures of Asher's bike when he found the issue in his bike.

That's when I removed my Uni and went back to OEM. When I checked my filter during my maintenance today, there was still some residual oil around the filter housing that I had to wipe off. My OEM filter looked great, so I blew it off and put it back. A $30 air filter every 8 or 12 thousand miles is too cheap to risk the problems.

I got tired of wiping down the daily drop of excess coming out of the filter. Never could get enough squeezed out of it. The Uni is out of the bike and I put in a new OEM (after giving everything a wipedown inside the air box). Eventually I suppose I'll try the Uni again one of these days, but only after giving it a thorough cleaning and using the Uni spray filter oil.
