great airbox tip. Keen to try positive pressure on my 890AR somehow. In your riding experience in Australia, generally speaking, do you reckon most filters get dusty from following others or dust being churned up from your own back tyre?

It’s so funny when you are ripping it up and my 2 year old points at the tv and says “dada..dada”. Then I just look at him and shake my head up and down and say “oh yeah bud that’s dada” knowing damn well that I’ll never be at that skill level😂😂

Adam, I work for a Filtration company- we always talk about a filtration train (multiple filters of different grades, coarser to finer) where the coarser filters protect the final filters. Each filter cuts down on the particulate load going through the next filter. You can then remove/clean the coarse filter when it blocks, in this case the foam filter. Technically the foam filter would be called a Depth filter which forces particles through a Tortuous path where particles are then removed from the air flow as they impinge on the filter media. Your fine filters (the paper elements) will filter fine particles from the air but they do not have a large dirt holding capacity. A bit technical but you explain it well to Non-filter people!

Have had my Africa Twin RD07A for 22 years and have always used foam filter over my paper filter.

Watching all your vids has given me a new ambition in life. My journey to get my motorcycle licence starts next week, at the age of 51. I want access to some of this fun!

Every time I see one of your videos I wonder why I don't watch your videos all the time, you are easily my favourite motorcycle KZfaqr I think you have exactly the right mindset about motorcycle's.

You wanna become a better rider , watch every video on this channel! This fella can ride with the best of em!

Was trying to think of the word and then you said it... stoked. It means so much more getting THAT amount of performance from an old bike. I'm done with listening to those pricks trying to tell me how great new bikes are and what makes them ride great. THEY are not great, they are HEAVY and over complicated heaps of shit and THEY can keep them and their never ending BS. Everything I have tried from your advice has improved my bike so I am listening to you. Thanks

Driving these bikes myself since the late 80`s and I am happy to see you giving them the credit they deserve. The biggest improvements for me was a "more" modern CDI unit, which totally changed the way the engine worked, as well as using fork emulators. Thank you for your excellent work and spirit!

How i love the way, we, the people who appreciate, and we are owners of this old Bikes, always find a way to improve these lovely machines... From Patagonia, i surely i'll take this tips to modify my 89' transalp to get it on dusty roads and adventure tracks!! Keep pushing the warhorse. Cheers from Argentina

Really cool advice that can benefit all of us with older machines. Keep up the great work Adam!

I love the work around! Also, I enjoy how much thought you’ve put into it. Good stuff

Thankyou for your video Adam, you show real motorbike passion. Love your work from Spain

That’s spot on that Adam. Makes sense. A lot of sports bikes have been using something similar, RAM air. Air is pushed in through from the front as you ride. Your new set up is the same.

These are the kinds of practical & experienced lessons are what I'm here for. Thank you for sharing your insight. Gratz on the 164 kph/101 mph.

Always learning from you. I've even startid a mechanic course on my own. Your existence, hints, job, life is my whole inspiration. Thank you so much Adam, Thank you! My the life give you awesome rides and joyful moments with family and friends. Cheers!

You're looking so happy during that presentation. Thanks a lot.

You’re an absolute beauty man. Hands down the most raw/ no bullshit, true enduro rider on KZfaq. Keep up the great content !!

Awesome content, been following since you got the WAR HORSE. My 2006 Honda TA has been running rich since my last dusty trip, and tomorrow I'm checking the air filter, which is washable and oiled. Thanks for your channel.

Best ADV channel. My favourite advice out there. And Adam's presentation is meditative.

Thank you for the extra knowledge regarding everything about air filter, air box, air flow, etc. It helped me to understand better the all concept.

The joy on your face and in your voice while talking about this!! Love it. Were those A-Star wellies?

I had the same model with 100 000km on clock. My first bike. Rd07 model solved the problem with airfilter putting it in fron of the gas tank. But i think they made it more road oriented. As always vids are so informative and full of passion for motorcycling even 10yrs after I started to follow.

Always good and informative to stop by at this channel. See you soon in Australia mate.

Interesting , this is why it’s good to talk to people who run in different conditions . I would not of thought so in depth about the air filter if I had not watched you riding in those talcum powder roads you have in Australia .

Geweldig dit kanaal de foto van mijn eerste rd04 hangt boven mijn bed rood wit blauw. Heb er drie gehad ook een rd03 geniale motoren . De rd07 ook twee gehad. Perfecte reis machines wordt hier zo blij van. Ook de modificaties en jou glimlach, terwijl je de mooiste en nieuwste machines kan rijden!!! Love it 👋🥳🙏👊✔️

Went in to update a new CC number and saw the levels you recently created...glad to upgrade and support a good man and his family. Cheers mate!

I binge watched the war horse series. I never thought to apply a foam pre filter over my paper one. Thank you for a great series.

Excellent advice! I am very conscious when it comes to what my dirt bike breathes (EXC500 2012) and in dusty conditions I short shift to take advantage of the torque (I also do it more regularly to keep the motor healthy for as long as I can). Lower gearing helps that too. Running 14/48 at the moment which for that bike and my riding is a golden medium. As always great clip man.

Mate, I love it when you talk (down) to the keyboard warriors. I constantly ask myself “why do people watch this stuff if all they want to do is say that you know nothing” !!! I’d love to know how many 4 Day Enduros, bike tests and international events they’ve done. Alex, I’ll listen to you mate, firstly I know sod all and second you tell a great story, your enthusiasm and knowledge is immense. And most of all I just love how much you love that bloody bike !! Good on ya mate.

Great you won't have problems with toasting the reg/rec on account of the relocation from earlier generations. Nice work on the improvement and the content. Love it. RD03 owner in Norway 🤟

Very interesting and instructive. I appreciate and understand more this knowledge about the concept of airflow. Thanks Adam!

Thanks for the tip that all the community will follow 😁. I suppressed the separation in the between the airbox and put a hand made filter inside like we have on enduro and mx bikes. I can feel increased air flow and better mids

Thoroughly enjoying the content Adam👌🏾

Love your new air intake system Adam. Another fab! video.

So glad you kept the FrankenScreen!😊

Hell yea!!! I’ll been waiting on the next video!!

Another great video - I am picking up my RD07 tomorrow and the inspiration for the project has all come from your enthusiasm. Ignore the nay sayers, my guess is none of them ride in anything close to the conditions in Oz so have no idea the issues it causes.

They have addressed this problem with dusting the filters on the new Africa Twin.. the intake is forward facing high up in the front. Thanks for the educational videos.. even though I drive a crf 1100.

Loving it - keep 'em coming!

Adam, you are awesome man. Keep it up 🤜🤛

Love it.......All the best from Canada!!

I like the stitches and scar in the windscreen. Saw the drop done in the Netherlands and how you fix it. So cool that you still have it like a war memory…. Cheers from Germany.

I wish I had something to contribute to your project but you have got it all covered.

Hi Adam Im an adventure rider in Alice Springs and a plastic welder. I can see some real easy mods i could help you with but understand you want to keep to standard as much as possible. Love your work !

Great episode with clear results. Advantages two, disadvantages zero. Thanks for showing us, Adam, what practical knowledge can do. Happy days with the Warhorse, Günter/Nürnberg

Really enjoy your videos 👍 cheers for making them.

you are an inspiration for the younger generation!

Thanks Mate! Gonna do exactly the same to my transalp ‘94 same airbox, same issue. Do a lot offroad in france and spain. I love your understanding of the air velocity and not having vacuum fuel abuse.

Mate top Stuff , tapped into what a lot of Men enjoy about Motor bikes and we see it in you . Stew Baylor Gncc on the Big Dog 450 yamaha made a easy win avoiding a filter change in super dusty conditions one round . Tightish bulldust like corners dusting out the traditional airbox location. The War Horse legendary .

The way you grin at 1:05 in anticipation makes me happy 😄

Great masterclass top. Amazing this Africa Twin

Brilliant as always Adam 👌

Love this videos Adam! Thank you❤

Thanks Adam very interesting info on the air box and air filter set up Just look the War Horse get up and go Thanks Dave

i remember back in 1997 when i got delivery of my new xr400r , still in the box at the dealership, the mechanic and i pulled out the air box and the intake pipe had this 1/4 inch cut that was vertical instead of the 40mm round hole, that was the restrictions put in for being road legal instead of off road use, it's had a big restricted spark arrestor and they had the carburettor running tiny jets, i was amazed at how much Honda restricted that bike. it was a fantastic bike after it got proper airflow through the motor. , it's been fantastic following along with your journey with the bikes over the past year

Excellent work as usual Aman. Go the horse 😎

God Bless you Adam and you take very good care of yourself my friend

Super awesome. Also, got a good chuckle when I noticed at the end of the video that your thumbnail pose includes the yard boots and a hoody. Cheers!

I have had to pause this at 1:45 mins just to comment on the absolute amazement at the way you ride the bike - I can’t even begin to comprehend how to cope with a drifting rear wheel without a major incident into the nearest hedge!

All your video are full life, experience and joy All the best 👍 for your future projects Stay Blessed. Lots of Love & Respect from Qatar 🇶🇦

It's interesting to notice how Honda have adressed this issue with the RD07 model. Until watching this video I never knew exactly about how the airbox was designed in the RD04. The RD07 has the airbox attached to the top of the carburetors and it sucks in air at the top of the fuel tank right behind the handlebar, so it doesn't have to deal with dust thrown up from any wheel, and you also can go through deeper water. Besides, they were able to lower the seat a bit by re-locating the airbox and also put the regulator/rectifier unit on the left hand side, away from the hot muffler. Great video again, Adam! Thanks!

Geez you look enthusiastic, missus must be so jealous 😜 Love what your doing and your camerawork rocks Also love the Frankenstein windscreen look

I love how proud you are of yourself 😄

Where it's at, always great advice and wholesomeness

Awsome information. Mine will be getting the same treatment later 👌

I have turned the pipe other way and closed air way so it can take air only from the front side to create positive preasure. Every part stayed original, didn't cut nothing..Thanks for the tip

Absolutely epic what you’ve done with this bike, giving it life from the very beginning finding it in that garage. I’m not sure I’d try a top speed run in no gloves though, you’ve got balls. 😅

Great educational video. Thank you so much!

Awesome work!

You're right, over the years, some of the crazy air intake positioning has baffled me. I have always attempted to clear it up. Sometimes successfully, other time with little effect. Even on my old 1600-2.0Lt Kombies of the 80-90s running foam pod filters has contributed to noticeable running efficiencies. Keeping the dust out of the engine bay and the fresh cool air coming in, was always a factor. Have a deposit down on a 450 Himalayan, one of the things I like is that air intake up high under the tank. One less problem to think on. It sports a paper filter, as long as I'm not trailing, all good. Can't wait to get my grubby hand on the ride. Maybe not so grubby these days. There are a few things I'm not sold on, but let's see in the next few years while I can still ride. Cheers.

Nothing says adventure more than donning a pair for wellies on the War Horse! Love the video

I was surprised with this video and had to check the books... my AT was born in 1993 and she has filter on top of the tank... yours must be the earlier one.

Makes sense, cheers mate

Brilliant practical engineering!

Greate video. Thanks for sharing your knowledge. And there will allways be someone that thinks they know better. People should learn to be quite and just listen for a change.

Waterproofing is such a cheap and cool improvement, it is so worth doing it besides if done right it will significantly improve the longevity, performance and economy

Totally awesome mate

Basic stuff, but just as important! Well done, good Sir. Oh, and I love your new adventure boots 🤭🤟

Amazing! Love it

Good to see you back in the dirt kitchen Adam😅 Seriously can't believe anyone would doubt ur knowledge of dirt bikes?? But I'm guessing there are a whole new generation of "adventure" know it all's these days 😅

Woow Adam now WARHORSE engine run soo smoooth👍💪, its Symphony for ears,,, Love IT💯❤‍🔥

Amazing achievement well done

This bike is becoming quite the treasure. Also, you're a brave man documenting your speeds, and then posting it to youTube too! Be careful out there!

Now that's what I call a useful video

I was looking for a collector bike, it was between the super tenere and the African twin. Found a perfect S10, so I got that, but it always bothered me that I maybe should have gotten the Honda. I thought they were very similar. Turns out that's not the case. Thanks! Love your channel!

Clever mod on the airbox… that’s a massive top speed difference!😲 I knew they weren’t going to be power houses, tuned for torque and all that… but I was shocked how low the stock HP figures were in your earlier video. Interesting point on the foam filter skin… we were discussing recently filter skins including using a pair of tights around the K&N cold air intake kits for desert use, or even round the snorkel intake. Definitely helps. Fine mesh and all that. 😅🤘 I always run the Twin Air dust and sand covers on my KTMs… people say… aww yeah, I change mine every ride bro… pffftt… I don’t. 😅 I grease the lip, grease the contact area, make sure the airbox is dripping a little and run those extra two filter skins. When it’s hard to start in the morning when it’s been out on the truck overnight in the damp/humidity then it’s time to change. Take the skins off and the filter still looks new. Still moist too. Can bang on a fresh sand skin if you’re caught short for time or clean filters. 😅🤘 Do it right the first time and save yourself a load of dicking about. 😅 Those skins are not for shovel hands though… wrecks them every time. 🥴 Better that than the motor though. 😂👌

Nice one Adam, it will be really interesting to see how much further you can go on a tank of fuel. Should see some real improvements on those long hauls in the outback. 👍🇦🇺

Man Ive gotta come down under maybe even move for the riding. What a place what a bike.

I took the airbox inspection cover off the klr650 and rode 300km. I got 24km per litre. Before it was 21kpL. When I put cover back on it felt like a wimpy puppy. 😊

Excellent theory! The free flow of clean air through a motor is truly needed to make an engine breath for maximum efficiency.

Nice mate, very similar to how the new WR’s airbox/ I take is. I have a 2020 husqvarna fe450 and my mates have 2023 wr450 and after the same amount of riding on the same track, same day - very big difference between air filter cleanliness. The big “snorkel” set up on the yammys are much better, not sucking up your own dust all the time.

Ive done this on a few of my bikes. easy mod to get better air in. My xt660x are very restrictive, DNA side filter fixed that, I got the ktm 690 airbox lid, That made a great improvement with the evo tune. My dads klr we removed the snorkel and made more holes, My xr400m we drilled 6 1" holes on the side. A built motor so needed the extra air. on our dirt bikes we always remove the little rubber snorkel but no holes as we cross water. easy mod for an small boost and a large boost with a tune.

Fab Adam so life affirming. Got my old man's head on now, get those gloves on!

Thank you for sharing.

I ride 2016 Africa Twin. Never liked the dual pleated paper filters and didn't want to go to K&N oiled. Watched what you did and ended up finding Uniflow filters there in Australia that sells and foam pre-filter with a very minor mod to the snorkels. I feel the 16 Africa Twin has a great air intake position just needed a little more for dirt. And now I feel I'll have that. Thanks for the thought process of finding a solution.

master is creating new ways!

Warhorse sounded like a completely different bike while you were at speed on track. I'm jealous! 😅

Engine sounds so healthy! 👌

👏🏼👏🏼👏🏼 so much truth in this video.
