Air filter help
By: truck11 Date: May 9, 2014, 7:42 am
---------------------------------------------------------
Need urgent help/suggestions. I 'just' realized the air filter
is a pleated paper style filter.... not very conducive to
dirt/dusty trail riding. What options are there (and that do
not require any 'mapping' changes)?
I need to figure something out quick... going trail riding next
Thursday. (Maybe it will just be muddy!)

I use a K&N Filter. I heard some people say they don't filter
dust that well but I haven't had any problems.

I got the UNI KTM 690 High Flow Air Filter from KTMtwins

And cut a some Flat UNI filter from Amazon. I ordered 3/8 & 5/8
both, but used the 3/8". Cut it to fit the outside of the
bottom part of the filter housing, so the top will hold it in
place. Cut out the corners for the screws. Be sure to get the
two tabs at the front put in place.

Now I can use regular filter oil. It was in place for the Big
Bend ride; there was very little dust on the flat filter where
the snout feeds-in.

I'm told that the 690 only requires mapping changes if you
modify the air box; a new foam filter alone won't change it so
much that a 15 minute idle won't allow the bike to adjust
itself. Here's an excerpt from an earlier post:
I forgot to mention, once the pipe is physically installed, you
have to conduct a 15-minute idle from a cold start. This causes
the KTM's fuel injection computer to reset itself to the pipe's
new parameters.
The procedure is just as simple as it sounds.
1. Start the bike when it's cold (as in first thing in the
morning).
2. Start a stopwatch. KTM designed this process to take 15
minutes. Be patient.
3. Do NOT touch the throttle AT ALL, or the process is reset and
you'll have to start over.
4. When the 15 minutes are up, don't touch the throttle, kill
the engine using the switch on the right side of the handlebar,
then kill power with the key.
5. You're done! Start your bike and go for a ride.
3 Tips:
1. For peace of mind, you may want to use a household fan to
blow at the radiator (your bike will get hot while sitting at
idle).
2. This process is only for fine tuning; it can't compensate for
something as drastic as opening the airbox. So until there's a
viable option for messing with the 2014's computer, leave the
air box alone--you've plenty of power!
3. Though I've not had to do this yet (living in Houston), I'm
told that this process can also help even out idle issues while
navigating extreme changes in elevation. So for those of you
crossing the Rockies, this might be a worth keeping in mind.
All this said, I went on a 12-hour desert rally a few months
ago. There were plenty of participants, so I was choking on
dust all day. Afterwards, I popped the air box cover and saw
that my filter was still looking new. I STILL haven't bothered
changing it. So your concern about the filter may be
unnecessary.
If you insist on a new filter, there are several out there but I
don't have any direct experience. I had a UniFilter on my last
bike and it worked fine.

I made my airbox & Wings mods at the same time. Did the 15
minute thing & have had no problems.

Thanks for the replies - I ended up getting the Unifilter pod
filter (dual pod looking one) - Part # NU-1417ST. Thank
goodness I called vendors before ordering - even though they
listed 'x' days shipping, they would not actually process the
shipment for 2-3 days! Really?? - found a vendor that had them
and could ship today (and pretty good price also) - hopefully it
will be here Tuesday!
I also talked to a guy at Unifilter who was very helpful. He
said it was basically the same filter as the 'orange Aussie
filter' but much cheaper (Aussie one is apparently like $140)
Normal foam filter care, nothing special required.

Truck11, did the filter seem to fit pretty well in your 2014? I
was reading the post another guy made saying his uni filter
actually bottomed out on the bottom of the air box. I've always
ran foam filters in my regular dirt bikes, and it's kind of
bugging me to only have one filter that isn't reusable for my
690 right now. Lol.

I did not really notice it bottoming out... and so what if it
does - still a good filter.

Haha good deal. I was just a bit worried that our 14s had a
different air box or something after reading that dudes post and
then seeing none of the websites listed the 14 for the uni.
Thanks for the reply, man. I'll probably be ordering one myself.

[/quote] NO- do NOT use the UNI US 1417 filter in the '14 as it
has a shallower box than previous model years - you will bottom
out on the bottom of the box, the filter will not lie flat on
the opening and you will pull out your brass airbox inserts
trying to get it to smoosh down. KTMtwins has removed the '14
from their compatibility chart. Use instead AU 1417, which still
bottoms out but only a little bit.
