Stewart, as a result of watching this video, I bought a DNA air filter for my car a Kia Picanto 1.25cc to replace the stock airbox filter. I wasn't expecting any performance difference at all, I just liked the idea of the long life of the product. Now I know that you are an honest and sensible guy, so I trusted your opinion and I am so glad that I did!. The filter has made a very noticeable improvement to the torque and runs more freely, the engine is more relaxed and copes with any situation that I ask of it!. The fuel economy has improved, acceleration is quicker, it really does feel like the car has had a larger engine fitted!
Induction roar on my Kymco AK550 with DNA was enhanced further by fitting a small aluminium louvered cover to the lid above the still air box. This lid is between the riders knees and not hidden/ sound muffled by a petrol tank. A most enjoyable sound further enhance by the Arrow exhaust muffler and 270 degree firing sequence. Brings joy to this 68 year old.
Another great video, on a product that seems Necessary! Amazing how manufacturers use budget parts on things that effect performance, a thing I noticed coming from the Harley world, a few quid at the manufacturing stage could add so much enjoyment for the owner. Another great common sence production. Keep up the great work.
If you were my teacher at school... I would have paid more attention. Excellent explanation. I'm test riding one of these tomorrow... can't wait! Been riding 3 years, my current bike is a suzuki gsf 650, but when I saw my boss rock up to work in his new royal enfield, I knew I wanted one... and tomorrow, I may be a proud owner.
I can't believe I watched a 15 minute video about an air filter. But it was very well done, and it convinced me to subscribe. I m still on the fence about buying an Interceptor but videos like this are warming me up to the idea that I could live with 45 horsepower.
@@stuartfillingham, honestly I'm really tempted because it looks so much like my first street legal bike, a 78 Honda CB550f. I even painted it almost that same burnt orange. Next summer it's either a new Royal Enfield or a used Honda CB1100ex. I'm getting old though, so the lighter R.E. is looking pretty good.
I have been reading these posts with interest because of a recent purchase of a DNA filter, this was purchased purely for the fact that it does not need to be replaced (only re-oiled). When I fitted the new filter I went through the 15 minute idle routine as mentioned in several posts and other bloggers, took the bike for a ride and the engine seemed to be struggling to accelerate smoothly especially from low revs and vibration. The next day the same result, the engine was definately down on performance in many ways and not pleasant to ride. I don't know anything about "self learning ECU's" or performance plugs but I do know that my ECU did not want to know about an increase in air flow from the new filter. As a possible solution to the self inflicted "problem" (the bike was working fine before the filter replacement) I replaced the original snorkel covering the air filter and went for a ride. Immediately the bike was buzzing along beautifully, smooth acceleration from any revs, the vibration problem disappeared and the world was wonderful again. So I'm happy with the result, a reusable air filter and a bike that puts a smile on my face when I ride it, life is good.
Hi from Argentina! I installed the DNA filter and have the same sensations as you. But you expressed them with the proper words. Thanks for the recomendation of run the engine 12 minutes, to allow the electronics make the necessary changes.
Hola Marcelo, que es lo que dice? que hay que dejar el motor funcionando con el nuevo filtro 12' en ralentí? para una moto refrigerada por aire me parece mucho.
Spend spend spend! Me too! Over the past 24 hours I have blown £70 on a luggage rack and £40 on a DNA filter for my classic 500. And it’s all Stu’s fault! I daren’t think about what I’m going to spend tomorrow. I might even get an Interceptor, after all, it’s only money 💸💸💸 PS: I might just go easy by following Stuart‘s recommendation by buying a NKG spark-plug. Oh, wait... 🤔
Thanks uncle Stu for the great explanation about the inner workings of the air filter. I've been using the DNA air filters on my bikes for at least 5 years now and I have been happy with them.
Stuart, slightly off topic but there is a very interesting article in the weeks MCN regarding S&S performance parts for the Enfield 650. These include stainless steel exhaust cans and a 865cc big bore kit. Well worth a read.
Excellent Video as always, Mr Fillingham.... Your video convinced me to go with DNA. I thought that I noticed a distinct new "growl" out of the engine after installing my new DNA air filter. Between the air filter and my new mufflers, I hear beautiful tones while riding my Interceptor on the beautiful roads of the Arkansas Ozarks......
Hi Stuart. Hitchcock superb service ,ordered filter and mirror plugs yesterday ,today all fitted run for 13mins then few miles around the town ,sounds great. Job done next Thanks to your videos 👍
Touring the USA on my Royal Enfield Interceptor 650, putting in a lot of miles per week it seemed like my life revolved around always cleaning, lubing, and adjusting the chain, trying to keep close the manufacturers recommend intervals 1,000km/621mi, which I can easily do in a day. I really wanted to keep My Royal Enfield stock but eventually broke down and installed the Bandidos Pitstop Belt Drive conversion kit. I love it! Even being very picky to clean off excess lube, after 17,000mi/27,000km it took forever to get it cleaned off all the little cracks and crevices. Plus it is smoother and quieter which I wasn't expecting. The downfall for my use is the gear ratio they use between the front and rear pulleys give more torque, which I don't care about while touring. That also means my gas mileage has gone down. I'm still using the stock paper filters. You mentioned in this video you would be checking for fuel consumption increase later. Did you check? What was the result? What video is it on? Thank you so much for your quality videos!
I was lucky I got a 2022 interceptor the other day With DNA filter fitted 16t sprocket, GT tank and bar risers fitted, like brand new with just over 1k miles on it, I won’t say hoe much it cost me but it was by far the best bargain I’ve ever purchased, I’m still in shock and absolutely love it,
Totally agree, fitted the DNA filter to my XT660Z Tenere and the best improvement is the 'characteristic' change..more important than HP figures. You are aware the engine is breathing better. A DNA filter and free flowing exhaust will make a big difference to the 'way' a bike rides. Cheers, Steve
Much appreciated Stuart. In the states we have K&N filters available. Quite similar. Added a couple of lower restriction mufflers and the sounds are glorious indeed from my GT650. I very much appreciate your attention to the details and nuances of wrenching on these bikes while delivering your message in poetic fashion. Thanks very much.
I have just installed the DNA filter on my Classic 350 (2022) and the performance is absolutely better. Sure it did not turn into a race bike but the ride is a delight even more so than before. I recommend it 100%. One note though: at least from my experience, the 12 minute idle run after installation did not do anything. On The first ride after installation, performance did not feel better and actually felt a bit worse than before, which was disappointing. I thought that’s the end of it. However, during my rides on the following days the engine felt better and better, like it’s “learning” during actual rides rather than running on idle.
Great video, really enjoyed your detailed commentary. So right about leaving the ECU to 'learn' too. I did the same mod a few years ago on a KTM Duke 390, with a K&N filter & my findings mirror yours.
Excellent video This is an upgrade that I'd decided to do on my Interceptor when I first found out about this product. I had a very similar setup on one of the bikes I had way back in the day and to be totally honest I didn't fit the filter just for a little bit of extra performance, because the bike didn't need it, I fitted the filter for that gorgeous sounding induction roar. I'm going to fully run my bike in before I change the filter because I want to be able to see what difference it makes.
Very helpful guide for those of us considering whether it's worth spending 80 quid on something that may give minimal improvement to performance & economy, bearing in mind the extra cost of its periodical cleaning & maintenance. You put my mind at rest regarding letting the ECU self-adjust after fitting this filter and slip-on pipes, so it's not necessary to remap or fit an expensive power module.
A rather splendid video descriptive my sir. It’s indescribable, the feeling of passing molecules onto the combustion chamber. Why would anyone someone suffocate such a power house
ok that does it! I'm not touching my bike until I check in with Stuart first. Thanks Stuart for explaining what I did incorrectly. I purchased the DNA filter a month ago not because I wanted more power but because I used to race off-road and I know the benefit of a high performance air filter for power consistency but also because it's cheaper in the long run to clean your filter instead of replacing it. But, my bikes never had fuel injection and an ECU so I replaced my stock filter with the DNA and rode the bike like I normally do to work. My INT is a commute bike and so it rode fine to work, but later in the day when I started it to go home, it wouldn't idle and it was very rough idling when I got it to start. I had to be careful on the way home to not let the revs drop below 3k or it would stall. When I got home I thought I must have done something wrong so I removed the filter and put back in the stock filter and left it that way for about a week. I then thought that was crazy as this must be working for others so I decided to trouble shoot it. I put it back in and started the bike and I must have gotten dumb lucky as I let it idle while I looked around. Of course there was nothing I could do so I didn't change anything but after a few minutes it seemed to be idling just fine. So I then took it out and rode it and stopped it and let it sit, and started it and rode it and everything seemed to be working properly. I then went back to commuting with the DNA installed and it's been great since. I agree that there really isn't anything noticeably different, but I wasn't expecting anything as my reason to install it is for better long term consistency and for a less costly maintenance. Thanks for the great write-up again!
Changing the stock air filter to the DNA Kit was the very first modification I did. The engine felt more powerful and responsive. Maybe also due to a noticeable increase in volume when fully opennig the throttle at medium revs. The induction noise might fool us, as our ears tend to make us feel that louder is quicker. Thank you for the information about the self learning process of the ECU. I'll go downstairs now an give the bike an idle run.
Sir, I was just blown away by the incredible amount of information you provided here! This screams of a real passion for motorbike, not just shallow throwing things at it. Thanks so much! I plan to get Int 650 myself, in Bakers Express colors. Would you by any chance adding any leather or waxed cloth vintage travel bags? Couldnt find any online without the need of a massive metal rack. Triumph has some nice looking bags
Sigh. Every time I come up with some question about how to make my INT 650 better, you have already elegantly, comprehensively, and satisfactorily answered it. Save some for the other RUclipsrs Mr. Fillingham! Thanks so much for your great videos.
Increase in torque is increase in power. Torque times revolutions equals power. One should maybe claim that not the >maximum< power is more, but the power over the mostly used rev band.
S&S filter and plate ordered. No DNA I. The states I could find. Nope don't have 100 miles on this motorcycle yet. Going to change the filter at my first service. Looking so forward to it though!!! Love your videos!
The air filter is important however I can't help but wonder what changes to the flywheel would do . The Enfield appears to be one of those bikes that responds to fettling. Bikes like this are rewarding to own . Keep the vids coming.
Love your vids , am 74 and worked my years in the industry , meaning incredible long rides for vacations on many different bikes , started on the first hondas than came to Canada a cub trail 50cc and ended with a Ducati my riding love affair . The desmodronic sound gave me biking orgasm
Great video Stuart, I hope they do the filter for the Himalayan 👍🏻, and you have an uncanny knack of making my bank account have less and less in it, every time you review something 🤣👍🏻
@Mark Dolby - HAHA! I too keep going shopping after his videos - first it was the Tank Knee Pads, then the Tank SS bag frame both from Motone Custom, Oxford heated hand grips - although I don't think he has discussed those or fitted them, and now the air filter and cover plate!
Stuart, I installed a DNA filter and bellmouth on my Meteor 350, and wow, what a difference! I followed your advice about letting it idle, but I let mine idle a little longer, as it was cold out today. I let mine idle for 15 minutes, so as to ensure that it had reached operating temperature. Then, I rode around my neighborhood to make sure the bike was all right. When that felt good, I went for a longer ride. While my Meteor 350 will never be a superbike, the DNA filter DEFINITELY woke it up! It pulls and accelerates in all gears, even in 5th. With the stock filter and snorkel, my bike didn't really pull in fifth; it felt like it had run out of breath-because it had. It pulls and accelerates more for sure. It also has a nice roar. I'm DEFINITELY glad I got the filter! Thanks again for the tip to warm up the bike first. Cheers!
Perfect timing, it’s an upgrade I’m planning to carry out. So it’s good to see a review beforehand. Great info regarding the ecu. Haven’t seen that mentioned anywhere else, so thanks for that. Cheers, Martin.
I think many people are just ignorant of it Martin, as with the LC Bonnevilles when they were first introduced. The ECU will cope eventually if you dont do it, but this way ensures a glitch free install.
Once again great video. Thank you for sharing. And yes, I think it's important to talk about fuel consumption. Some people are worried because RE claimed 70 mpg but in reality makes much less. Would be nice if with this k&n filter got a better fuel consumption. 🎅🤶
regarding the Tip to Letting the Engine run at idle to its optimum operating temperature, some say you need to wait until the fan starts to operate. this applies to water-cooled motors, so your Triumph might need this if you ever do the same thing on it. I don't know if it is true or not but it seems many say to wait until the fan kicks in.
Just fitted the DNA filterto my Interceptor; I agree entirely . I particularly noticed a difference on roll on, and also a livelier response. Thanks for talking me in to buying one, not just the filter but the bike.
You remind me of phaedrus from Robert M Pirsig's 'Zen and the art of motorcycle maintenance' Stuart! :) Delighted to have subscribed to your channel. My Interceptor is running in at the moment :)
I suggested watching this video to a friend who owns an Intercepter. Extolling lyrical about a new free flowing air filter. He looked up the particular item in question and said it costs ninety or more pounds !!...depending where you look...I remember buying a K&N filter for my Striple, it wasn't anything like that price... Why is the price so high??..... Okay, it last a lifetime, its a one off buy, but even so its pricy compered to over conversions...
Its great when one makes small modes and feels a significant improvement...( I changed the Air filter system ...K'n'N...on my Striple, to find the engine more eager) What's next Stu?, Ace bars, Meggas, a new leather jacket with artwork proclaiming you're a badarse ''Rocker''. Seriously though, I watched a guy fitting some new Megaphone exhausts to his Intercepter....gave it a nice 'growl' without annoying the neighbours...Greeting from España
Hi Mr. Straut, great content and much relevant to us normal riders. I have seen a lot of pistons getting fried because the engine was running lean. Please let us know your comments on long term effect of performance air filters. does learning ecu helps in solving this issue of running lean??
Usually, you would want to get a tune right away since now allowing more flow thru the air filter you have now kind of changed the air fuel mix ratio. But like you said the ecu will make adjustments but idk how true that is tho.
I’m buying this filter right away after seeing your video @stuartfillingham sir amazing and super informative as always -inwas in 2minds till now but this has clarified all my doubts-id thank you sir for these informative videos and please keep more of such videos -thank you once again!!
HI Stuart, Love your videos sir and this being my first bike I really appreciate any English spoken content and tips/recommendations. I am definitely going to purchase those 22mm handlebar risers from Motone based on your recommendation (wish you had even a 1% discount code so that you would gain more recognition from that company). I already purchased the tank pads, which were an absolute gem of an addition to the bike ergonomics and control. I have done many snorkel deletions on my vehicles and I always love added roar. My thoughts on this particular subject (mostly curious to my inexperience with bikes) is that sometimes I have read about user error when oiling performance filters. In particular, a user will over oil the filter and this residue will then build up on the MAF (mass air flow sensor) which in return will affect the fuel/air ratio reading by the ECU. Now from my own personal experience (still speaking of applications related to 4 wheeled vehicles) in using K&N filters and applying oil understanding this method... There is always some form or residual that will build up on the inside walls of the intake plastics that will lead to additional cleaning, but with a motorcycle having such a short intake setup; I am wondering if the oil residue would be sucked into a harder to reach area and cause additional maintenance? I always try to find an oil less performance filters, but I think that cuts into companies revenue stream in relation to the oil servicing kits. You mentioned that the rain guard on the intakes are usually installed by the factory keeping in mind to avoid any unnecessary water being sucked into the intake. If I am wanting to ride my bike this winter do you think that it would have any consequences leaving it that exposed when installing this kit? My thoughts are that the main market of the RE lineup being based in India, is that they would also want to keep dust pickup to a minimum. Apologies for any poor verbiage and I wholeheartedly appreciate your great content!
Appreciate the video. Trying to sneak the S&S slip-ons past the missus for my new RE GT 650. Clearly, I also need to get the S&S (DNA) air filter at the same time. Bugger. ;) Fitted the S&S air filter last night... ;)
Hi Stuart, I love your very informative and exhaustive videos 👍🏻. I need a clarification though. Isn’t the stage 2 kit meant to be used with free flow cans? Or can we use the DNA air filter along with the stage 2 kit with the stock exhausts without any heating or engine issues.
Air box and filter design have come a long way since the days of my '71 Commando. There, no thought given to preventing water egress, just a housing of perforated metal. Left me stuck on number of times on the side of the road in pouring rain.
I wouldn’t think that a little water sucked through would do your engine anything but good. Read quite a bit about water injection and seems like it’d do some good to get an occasional squirt!
Hey Stuart, what’s your take on using this type of free flow filter with stock exhaust? I am not looking for any major power upgrade but always liked the idea of things being more smoother. Will the engine be affected in anyway if I use this with stock exhaust?
I would have never thought be so interested by an air filter présentation... Thanks sir, interesting and informative, as usual ! Hi from Paris.
Extremely well-explained, Stuart. And a great tip regarding idling the engine from cold to normal running temperature.
Thanks. This is a no-bullshit channel. No hype. Very helpful. Unique and pleasant accent. Keep it going, I will buy an Interceptor very soon.
I didn't think that I needed to upgrade my Interceptor's air filter. But now after seeing your review I think I'll upgrade.
It would be a downgrade don't do it!
Stewart, as a result of watching this video, I bought a DNA air filter for my car a Kia Picanto 1.25cc to replace the stock airbox

Great stuff! I’ve always fitted a washable filter to all my vehicles. Pays for itself after a little while, better performance & mpg 👍🏻
Induction roar on my Kymco AK550 with DNA was enhanced further by fitting a small aluminium louvered cover to the lid above the still air box. This lid is between the riders knees and not hidden/ sound muffled by a petrol tank. A most enjoyable sound further enhance by the Arrow exhaust muffler and 270 degree firing sequence.

Maybe also due to a noticeable increase in volume when fully opennig the throttle at medium revs. The induction noise might fool us, as our ears tend to make us feel that louder is quicker. Thank you for the information about the self learning process of the ECU. I'll go downstairs now an give the bike an idle run.
no need if you've been running it for a while. they do sort themselves out eventually.
A Shakespearean delivery of an otherwise mundane subject. Thanks!
Excellent video, fantastic explanation, going to fit one to my Super Meteor 650 today. 👍
Sir, I was just blown away by the incredible amount of information you provided here! This screams of a real passion for motorbike, not just shallow throwing things at it. Thanks so much! I plan to get Int 650 myself, in Bakers Express colors. Would you by any chance adding any leather or waxed cloth vintage travel bags? Couldnt find any online without the need of a massive metal rack. Triumph has some nice looking bags
ill look into it when I can.
Thank you Stuart. This is a fantastic piece of information that is so important to the performance of the Interceptor.
Thanks again, Stuart. You've answered my question about the difference between S&S and DNA filters - they are the same! :)
Just ordered one for the RE Meteor Fireball red. Thanks for the vid.😎
Great info for "rookies." Have a great day Stuart.
Sigh. Every time I come up with some question about how to make my INT 650 better, you have already elegantly, comprehensively, and satisfactorily answered it. Save some for the other RUclipsrs Mr. Fillingham! Thanks so much for your great videos.
Increase in torque is increase in power. Torque times revolutions equals power. One should maybe claim that not the >maximum< power is more, but the power over the mostly used rev band.
S&S filter and plate ordered. No DNA I. The states I could find. Nope don't have 100 miles on this motorcycle yet. Going to change the filter at my first service. Looking so forward to it though!!!
Love your videos!
Stuart, I like the way you explain things
Fascinating presentation with equally fascinating accent.
The air filter is important however I can't help but wonder what changes to the flywheel would do .
The Enfield appears to be one of those bikes that responds to fettling.
Bikes like this are rewarding to own .
Keep the vids coming.
This is one of the first Mods that I did.....
Absolute delight to listen and watch your videos ! Thanks again Stuart !
Love your vids , am 74 and worked my years in the industry , meaning incredible long rides for vacations on many different bikes , started on the first hondas than came to Canada a cub trail 50cc and ended with a Ducati my riding love affair . The desmodronic sound gave me biking orgasm
Great explanation! I just ordered my kit for my brand new black interceptor 650.
Great video Stuart, I hope they do the filter for the Himalayan 👍🏻, and you have an uncanny knack of making my bank account have less and less in it, every time you review something 🤣👍🏻
@Mark Dolby - HAHA! I too keep going shopping after his videos - first it was the Tank Knee Pads, then the Tank SS bag frame both from Motone Custom, Oxford heated hand grips - although I don't think he has discussed those or fitted them, and now the air filter and cover plate!
RE650NZINT 😂 I know what you mean, I now have cameras outside watching the garage, and it looks like I’ll be getting a bike dryer too 😂👍🏻
Thank you very much, Stuart! You are truly the treasure trove of information! ATB🙏🏻🍀
Stuart, I installed a DNA filter and bellmouth on my Meteor 350, and wow, what a difference! I followed your advice about letting it idle, but I let mine idle a little longer, as it was cold out today. I let mine idle for 15 minutes, so as to ensure that it had reached operating temperature. Then, I rode around my neighborhood to make sure the bike was all right. When that felt good, I went for a longer ride. While my Meteor 350 will never be a superbike, the DNA filter DEFINITELY woke it up! It pulls and accelerates in all gears, even in 5th. With the stock filter and snorkel, my bike didn't really pull in fifth; it felt like it had run out of breath-because it had. It pulls and accelerates more for sure. It also has a nice roar. I'm DEFINITELY glad I got the filter! Thanks again for the tip to warm up the bike first. Cheers!
I don't know... Have seen fine particles and fine dust on an intake (clean side) personally on oil cotton filters... Mind you this was on cars.
Nice? good? I don't know what to comment.
Thank you as usual and I will try to get this upgrade for my INT.
definitely going to have a go at that mod. Cheers Stuart. Always excellent information.
Dear Stuart, it is always a pleasure and education watching your videos. Keep up the good work.
Perfect timing, it’s an upgrade I’m planning to carry out. So it’s good to see a review beforehand. Great info regarding the ecu. Haven’t seen that mentioned anywhere else, so thanks for that.
Cheers, Martin.
I think many people are just ignorant of it Martin, as with the LC Bonnevilles when they were first introduced. The ECU will cope eventually if you dont do it, but this way ensures a glitch free install.
Man, your videos are documentaries hahaha thank you for this and my bike is not even a Royal Enfield
I always enjoy your videos. Very informative
Once again great video. Thank you for sharing. And yes, I think it's important to talk about fuel consumption. Some people are worried because RE claimed 70 mpg but in reality makes much less. Would be nice if with this k&n filter got a better fuel consumption. 🎅🤶
My 2022 Euro 5 iteration consistently gets 87-90 kpg (imperial). Original factory filter over 10,000 km so far.
Such an elaborate explanation!!! Excellent.
First class video Stuart, informative and interesting and beautifully shot too, i never thought an air filter could be made to look sexy lol
That ECU was very important, thanks. And damn those leather wrapped grips look fantastic.
regarding the Tip to Letting the Engine run at idle to its optimum operating temperature, some say you need to wait until the fan starts to operate. this applies to water-cooled motors, so your Triumph might need this if you ever do the same thing on it. I don't know if it is true or not but it seems many say to wait until the fan kicks in.
Just fitted the DNA filterto my Interceptor; I agree entirely . I particularly noticed a difference on roll on, and also a livelier response.
Thanks for talking me in to buying one, not just the filter but the bike.
You remind me of phaedrus from Robert M Pirsig's 'Zen and the art of motorcycle maintenance' Stuart! :) Delighted to have subscribed to your channel. My Interceptor is running in at the moment :)
Another spot on, very good and instructive video Stuart.
By the way I learned something new today! Thank you!
I suggested watching this video to a friend who owns an Intercepter. Extolling lyrical about a new free flowing air filter. He looked up the particular item in question and said it costs ninety or more pounds !!...depending where you look...I remember buying a K&N filter for my Striple, it wasn't anything like that price... Why is the price so high??..... Okay, it last a lifetime, its a one off buy, but even so its pricy compered to over conversions...
Its great when one makes small modes and feels a significant improvement...( I changed the Air filter system ...K'n'N...on my Striple, to find the engine more eager) What's next Stu?, Ace bars, Meggas, a new leather jacket with artwork proclaiming you're a badarse ''Rocker''. Seriously though, I watched a guy fitting some new Megaphone exhausts to his Intercepter....gave it a nice 'growl' without annoying the neighbours...Greeting from España
Hi Mr. Straut, great content and much relevant to us normal riders. I have seen a lot of pistons getting fried because the engine was running lean. Please let us know your comments on long term effect of performance air filters. does learning ecu helps in solving this issue of running lean??
I would have thought a clogged air filter would make a bike run rich ?
Cracking little review, very interesting and informative as usual.
@Stuart brilliant mate and explained very well. Makes a lot of sense
Usually, you would want to get a tune right away since now allowing more flow thru the air filter you have now kind of changed the air fuel mix ratio. But like you said the ecu will make adjustments but idk how true that is tho.
Was waiting for it. 👍
I’m buying this filter right away after seeing your video @stuartfillingham sir amazing and super informative as always -inwas in 2minds till now but this has clarified all my doubts-id thank you sir for these informative videos and please keep more of such videos -thank you once again!!
HI Stuart, Love your videos sir and this being my first bike I really appreciate any English spoken content and tips/recommendations. I am definitely going to purchase those 22mm handlebar risers from Motone based on your recommendation (wish you had even a 1% discount code so that you would gain more recognition from that company). I already purchased the tank pads, which were an absolute gem of an addition to the bike ergonomics and control. I have done many snorkel deletions on my vehicles and I always love added roar. My thoughts on this particular subject (mostly curious to my inexperience with bikes) is that sometimes I have read about user error when oiling performance filters. In particular, a user will over oil the filter and this residue will then build up on the MAF (mass air flow sensor) which in return will affect the fuel/air ratio reading by the ECU. Now from my own personal experience (still speaking of applications related to 4 wheeled vehicles) in using K&N filters and applying oil understanding this method... There is always some form or residual that will build up on the inside walls of the intake plastics that will lead to additional cleaning, but with a motorcycle having such a short intake setup; I am wondering if the oil residue would be sucked into a harder to reach area and cause additional maintenance? I always try to find an oil less performance filters, but I think that cuts into companies revenue stream in relation to the oil servicing kits.
You mentioned that the rain guard on the intakes are usually installed by the factory keeping in mind to avoid any unnecessary water being sucked into the intake. If I am wanting to ride my bike this winter do you think that it would have any consequences leaving it that exposed when installing this kit? My thoughts are that the main market of the RE lineup being based in India, is that they would also want to keep dust pickup to a minimum.
Apologies for any poor verbiage and I wholeheartedly appreciate your great content!
I dont think you really need to worry about water ingress. perhaps just need to be a little more careful with the hose while washing!
Appreciate the video. Trying to sneak the S&S slip-ons past the missus for my new RE GT 650. Clearly, I also need to get the S&S (DNA) air filter at the same time. Bugger. ;)
Fitted the S&S air filter last night... ;)
A good air filter permits a hotter spark accelerating the flame flash , all in all the bike responds faster to acelleration
Hi Stuart, I love your very informative and exhaustive videos 👍🏻. I need a clarification though. Isn’t the stage 2 kit meant to be used with free flow cans? Or can we use the DNA air filter along with the stage 2 kit with the stock exhausts without any heating or engine issues.
I have the same question.
following
Great explanation and excellent video. Through and exhaustive 👍🏻
Air box and filter design have come a long way since the days of my '71 Commando. There, no thought given to preventing water egress, just a housing of perforated metal. Left me stuck on number of times on the side of the road in pouring rain.
12:27, oh remember the days when we weren't fleeced quite as much at the pumps....
Nice production without waffle.
Thank you. Some really great info!
I wouldn’t think that a little water sucked through would do your engine anything but good. Read quite a bit about water injection and seems like it’d do some good to get an occasional squirt!
Well that review got you a lifetime supply😁👍Great review and good advice.
Hey Stuart, what’s your take on using this type of free flow filter with stock exhaust? I am not looking for any major power upgrade but always liked the idea of things being more smoother. Will the engine be affected in anyway if I use this with stock exhaust?
Great tip with the retract👍
