So lots of dirt got in the motor.
I currently have the same issue. Did you replace the airbox or go some other route? We aren't the only ones that got bit by the improper UNI filter design.
I'm toying with a few possible solutions to get me to the dead of winter when I'll have more time to mess with it and perhaps there will be some interesting options out.
This is my solution
To windblown101 what was the issue with the Uni Filter? I am running this with snorkel pre filters and mine is perfect. Just got back from a 6 day ride in dusty conditions and it is clean.
Specifically I'm talking about the Aussie UNI filter with the metal frame. The sealing rubber used on it is quite hard and a bit too thick. This generates a lot of pressure against the airbox when the wedge is pushed home which would be great except the airbox side is not designed with enough strength to stay true with that much pressure on it and the top center of the airbox side warps away from the filter seal. This lets dust get sucked in at the top and completely bypass the filter.
Here are some photos to demonstrate. I greased the seal. Installed it in the airbox and seated the retaining wedge.
You can see that the grease got squeezed out everywhere except at the top where the air filter seal never even touched the airbox sealing edge.
I took the airbox out and cleaned it, throttle body valves was clean so I think I’m safe for now.
Was out riding this weekend and the box looks better this time around.
Quite a lot of overflow from crankcase when I looked. And a O-ring from air temp sensor
Amazed how much the bike kicks up dust, snorkels socks looked horrible even tho I’m up front of the pack navigating the entire weekend.
Yep. It's great that KTM moved the filter on the big bikes out from under the tank but kind of wish they had put it where the battery is and moved the battery back. I ride mostly solo and have noticed the filter gets a pretty good workout.
I have the KTM pre filter and the filter sock from Uni on my 1290 because you can't get to the airfilter to clean it. On the 790, I just end up cleaning the prefilter like all the time. If I'm going on a long, multi-day ride offroad, I'll take the 2 spare Rottweiler prefilters in a bag already oiled up. I've removed the snorkels which you could argue puts the intake location closer to the tail which ingests a lot of dust.
I carry a few pre-oiled Rottweiler Power plate duel density filters as well while on multi day trips. Best idea ever.
The 1190 I have the Rottweiler intake with a few pre-filters as well. It normally takes 15 or 20 minutes to get to the 1190 air filter however my record is 9 minutes.
I seem to be in the same boat, here in Israel.
I just ordered the Guglatech air filter, but can't find anyone who'll ship this Rock Oil stuff to Israel (besides bestrest who sell a tiny bottle, and the shipping to here costs more than double the cost of the oil).
Can anyone here recommend a good substitute oil for using with this filter?
From what I saw in the thread the only other oil that @guglemonster recommends is the K&N cotton filter stuff. I'd prefer a water washable solution if such exists...
I borrowed a little Rock Oil from a buddy on a riding trip recently, and found that it looked and smelled exactly like No Toil red filter oil, which is also water soluble.
filter will arrive Desert Ready, meaning oiled and prepped for the Desert, we cannot ship the Rock Oil, sorry, if you wish to use another oil, follow than their procedure, no petrol-based oil in the drain please do not use No Toil, we had reports of very poor dust trapping, we did not test it on our matrix though
got with a cotton or foam oil, and grease the rim (plus our Frame fix )
cheers and thank you
the smell comes from the alcohol base, how can you tell if the oil/liquid will perform equally? it's there to trap particle smaller than 10 microns, use a foam oil from a good brand instead
I cannot recommend it, sorry
OK. I promise to try to not dump any petrol based oil in the drain...
just wanted to confirm that standard oils and detergents sold locally such as K&N, Motorex, Putoline etc. won't harm your filter.
we tested K&N, no big deal, many customers use Motul, some Motorex, unless you use solvents or pure petrol, the products recommended by any producer to clean their stuff should be pretty safe for our filters too, notoil excluded
Hello @guglemonster, could you please provide more detail on your "frame fix"?
we even made a video and all pictures are on our web too
with such a hard frame I doubt it may help, UNI is really problematic deforming the plastic wedges in some cases
here's the video
one of our in mates, to "fix the uni", had to use a file and working some time to even-up the surface and allow normal closing, cannot remember his nick though, sorry
What is the final solution to the air filter issues? Were these issues carried over to the 890 models. I would like to get ahead of the problem if I can
