- KTM Owners seem to like the open style air filters and airbox - Such as the Rottweiler or this type of filter we are using in this video. So we took this opportunity to do a comparison video for you all :0)
Brilliant.
Interesting. I suspect the DNA filter may actually be restricting top end airflow as it's bottom is solid, which causes the air to make a right angle turn at the filter's bottom, instead of flowing straight down like the stock filter. Further speculating, the side discharged air, after hitting the solid bottom of the filter, then hits the inside walls of the airbox and has to make yet another turn. You'd think getting rid of the obviously ridiculous snorkel would matter a lot more, but perhaps the side exit of the air from the DNA is creating a resonance, turbulence or a restriction at higher RPM.
For one reason or another, that filter is creating a top end issue that can't be tuned out. A flat panel filter like the Twin Air may be better, it would be interesting to test that as perhaps you can indeed have your cake and eat it too, with the fat midrange gains realized and at the very least a bit more than stock top end. If not, then the tradeoff is worth it, as big thumpers are all about that fat midrange and those are some nice gains!
23 Husky 701 Enduro here. Running the stock snorkel with the last 2/3 of it removed and the front part still in place but with the "floor" of the snorkel removed. The residual top of the snorkel helps to keep water out of the filter element if it rains or during washing. It also spreads dust far more evenly over the filter, the stock setup concentrates all the dirt to a small area on the front of the filter. Speaking of the filter, since it's an Enduro that sees off road, it is running a Twin Air flat panel oiled foam filter.
Tuning mods are a Yosh RS-4 can with spark arrestor screen but no DB killer, Rottweiler's O2 eliminator dongle and a PC6 with their map. I've not dyno'd it, but the bike is a monster with loads of smooth power everywhere, perhaps a little much for it's dual sport semi knobby tire Enduro format! As with the bike in the video, the low end and midrange gains are impressive.
It's not just "seat of the pants" as the bike can accelerate from lower RPM in taller gears in a way that it couldn't when it was stock, and 2nd gear wheelies are much easier to initiate, even with taller +1/-1 16/45 gearing. Top end is nuts, a good sign there is at high revs if ya give it 75% throttle and then roll it on to full throttle, there is notably stronger acceleration, blasting past 100 MPH very quickly. The modded motor has abundant power out the wazoo and probably more fun than I should probably be allowed to have.
It is too bad the 690 platform is so choked up in stock form, but the difference in the post tuning riding experience is just ridiculous, which is good for tuner's business 😆
we are getting the bike back in with a different exhaust so we will do a follow up video.
How about trying the stock airbox with a cotton oiled filter (K&N) and a DECATed exhaust? Have bike, can supply
Wouldn't the best setup be stock air filter, de-cat performance exhaust and the power commander with tuning?
all depends... some set-up give more top end some more midrange. from a consistency of mapping.... i have to say stock airbox work better
I got confused when you started talking about the BMC filter. Thought that was another configuration that you tested but I guess you actually meant DNA?
ah... you spotted the deliberate mistake :0). Your right.... I did say BMC for some odd reason
Can the 2014 Duke 690R stock ECU be reflash for fuel/timing for 100 octane pump gas?
it can....
Nice video. Full open dvr pipe or is the db killer mounted?
you know what, I cant recall....
Looks like db removed
Perhaps the stock airbox is designed to resonate at about 8k rpm?
we are getting the bike back in with a different exhaust so we will do a follow up video.
Seen this before with the DVR system its usually caused by the CAT/Baffle still being in the exhaust
This is my bike and had to tighten the endcan bracket up as it was loose. Tony did mention there was a little device sitting in the link pipe/ endcan...took it off and it fell out 😅 I guess it will have to go back for a little tweak at some point during winter
@@ethansenior9918 Thanks for letting us know. looking forward to the next tweak.
That’s interesting. I’ve done others that were like this with a Rottweiler filter and full systems but never this set-up. Interesting what you say….. something that worth looking at in the future for back2back testing perhaps
@@ethansenior9918 bloody single cylinder vibrating themselves to bits 🙈 how big was that mesh?
Like to see a no air filter test too.
we will bear that in mind if we have another come in
