As a Yank who bought his Classic 350 about a month ago, I did find this video informative enough to actually order the new filter cover from Hitchcock's as well as a bit of touch-up paint. I also enjoyed the ride down those beautiful UK country roads.
I've fitted one last week after watching your video, and yep it's made a noticeable difference, well pleased with it, cheers for the pointer ,and a bargain for £26 delivered! 👍 Next thing will be the decat pipe!
@@ianhughesroyalenfield Hi Ian , I fitted a decat pipe but I took the cheap option of going to my local car exhaust specialist that do custom systems for cars , and asked them to cut me a 435mm length of 39mm stainless pipe and flare the ends out to 40mm ID at the front and 40mm OD at the rear to fit my silencer and header pipe, the front end I've slid directly over the header pipe, and the back end inside the silencer seal , I had to fit a new clamp at the front, and it works perfectly, and sounds fantastic with the standard silencer! The cost was the grand total of £30 and some heat proof matt black I had already in the garage! It runs a lot better throughout the rev range as well . Obviously I haven't got the heat shield anymore as I haven't welded the nut lugs on but I'm not bothered about that , or the mid section hanging bracket , the clamps at each end hold it firmly in place . 👍
Designed and 3d printed same thing, just installed it at otherwise stock bike, still in run in period. It definitively pulls little better, and i noticed it pops more from exhaust during slow riding gear change. Definitively sign it is getting more air and running at leaner mixture.
The de-cat helped with the sound, best thing I did 😉 I might just go the whole hog, and buy the filter too, but it will have to wait, more pressing things to pay for 🙄😂 Stay safe, and enjoy the ride 😎
I think the DNA filter itself is unnecessary but just replacing the venturi cover from Hitchcocks away from the snail type should be just as good. I heard from an Enfield engineer that letting the engine idle for 5-10 minutes is a waste of time, it just isn't necessary. P.S, Video at 07:35 to 08:06 I know how motorists feel about walkers enjoying the countryside but I would delete your personal comments at that scene. Be thankful they were walking on the correct side of the road for oncoming traffic. The horse-crap is definitely a hazard for motorcyclists. Other than that, it's an informative video.
The Hitchcock’s de-cat is really good quality. Just a tip, allow a bit of the gasket to protrude from the de-cat pipe at the down pipe end, so when clamped up, it won’t shoot inside the pipe (as I found out 🙄) 👍
Lovely ride, enjoyed that, cheers. Nice mod to Clem, ur right she does sound nice, especially on the overrun. Gotta DNA on Edna our Inty; deffo feel a lil bit of a performance boost. Gonna put one on Hera our Himmy; see what that does. Mind how you go Ian, our best to Anne too. Cheers Neil
I think the cover is a sound only change. Maybe. I have K&N filters in car and truck and bike all make noticeable difference. Your stock cover is tuned for noise reduction interesting to see if it is less open area than the new one. Great vid really good riding style for exciting show. Thanks.
Yes they do, but that is irreversible if they don’t like the sound. By buying and fitting an open intake, if the noise is too much, it’s easy to return to standard……which is actually what I ended up doing 😉
Morning Ian I fitted the full DNA filter kit on both made a difference but personally I think it uses a bit more fuel Andy from bellas adventures said the same but to me worth the money to just to hear the better induction sound 👍👍
I will see how we go with just the cover for now, but as the Classic 350 does a ridiculous amount of mpg, a few less won’t overly bother me. I found that it also exaggerates the exhaust volume too. 😎
A dino test might settle any doubts about the perceived benefits of swapping out the standard air filter. Or a vacuum gauge to show the resistance to sucking air into the engine with the different filter arrangements.🙂
Yes, don’t hold your breath. If this genuinely add more Torque/HP the manufacturer would dyno the bike and post the results. Complete snake oil. Those who like to pull off or open up airbox’s should read up on “resonant motorcycle air-box’s to understand what it is doing.
Interesting comment. I believe most owners aren’t expecting any/much power increase, rather attempting to help the engine breathe more efficiently. Are you saying that is also not true or false info being banded about the internet?
As you probably know, though I doubt Terence does, I have fitted a K n N to my Interceptor, plus Scorpion pipes, plus fitted a booster plug. That definitely works, and no it has been dyno tested 😂
After a while, I removed the open air intake, and replaced it with the original, as the roar gave me a headache on longer rides. I still have the original fitted now. Eventually, I would like to fit the DNA filter, but with the standard air intake, fit the fuel x lite and would like the cam. Another UA-camr you maybe aware of youtube.com/@TheNorfolkThunderbolt?si=TyQt2YSNIocX6hWo has already fitted some of these, and has the cam ready to fit too. I am following him on this journey, he is also a thoroughly nice chap too. Hope this helps.
@@ianhughesroyalenfield thankyou very much for your reply, i am wondering if fitting the performance cam might put extra strain on other engine components like the crankshaft? When I have my classic 350 I will be checking with Enfield first before changing things?
@MsDenver2 morning Donna. Tigerness has also been busy modifying his 350, here is a link to one of his ua-cam.com/video/kaUzgE9iFQk/v-deo.htmlsi=AEb33Agac2iXbfP1 where he has fitted the decat, the DNA filter and camshaft. The engine is so under stressed, there haven’t been any negative reports after fitting the cam. The ecu still restricts overall performance to 73mph, but the cam changes how the engine performs to that point. I think if you contacted RE, they would say not to carry out any mods to your bike. Any manufacturer would say the same. Cheers
She feels a bit more eager, and I imagine that fitting the free flow filter would improve it even further. I haven’t a clue about gas mileage, as I never keep an eye on it, I just fill the tank when needed and ride. They do enough mpg to not worry about losing a few, if any. Nice to have comments from the U.S, cheers
Makes a difference to the pull Ian doesn’t it 😁 be good to ride it back to back with another with both stage 1 and 2 to see the difference as the stage 1 is quite pricey, I like the induction roar 😁👍 let it breath and let it rev! 😁👍 Cheers Bruce
@@ianhughesroyalenfield I should refit my stock filter with open end cap like you have and see if any difference 🧐 could save you £70ish but I imagine the more air flowing stage 1 filter will be better 👍 There is definitely more mid range power available with both mods along with a deCAT pipe, non believers are welcome to have a go of my bike to feel the benefits😁 even with buzzy trail tyres 🤣👍
Definitely more zip. For how easy it is to swap over, you could just try it, and put a vid up on your thoughts. Ok, it won’t be a full on ; Dyno techno test, but it would give peeps an insight on your thoughts. 😎👍
I would leave standard air filter in. More air. Also more crap. Spend the money on petrol. Shawn smoak was showing difference between 2 bmw gs. One standard. One with popular after market air filter but he did.nt mention names. Clean cylinder heads on standard. Non standard was full of dirty deposits. Shawn is pro mechanic in Washington if you don't know him. Cover won t be a prob. Maybe a de cat pipe. But for me bike runs fine as standard. 👍
Yeah bikes run fine as standard, unfortunately especially with the modern eco restrictive requirements they also run better if you un-strangle the engines 'breathing'
Good evening Donna. No noticeable difference, but then again, as the 350 is so economical, I have never checked mpg. When the gauge shows a couple of bars, I top up.
Sound of the exhaust seems louder, but intake roar is also louder. The intake roar, is the reason I have put the original cover back on, as it gave me a headache on longer rides.
@@90gen26 well, I have just the decat now. Runs and sounds perfect to me. If you have a look at some of my newer videos, I think you will get a decent idea of how it sounds.
That’s what I did, and no. It does let the engine breathe a tiny bit better, but there is quite a difference in intake roar. I ended up putting the original back in place.
@@Mr.han_777-v2y you will never get a massive increase in performance from the j series 350. What you will be doing, is simply allowing the engine to breathe better. Maybe giving a bit more acceleration and throttle response, but it won’t be much. Even if you also fit a free flow (straight through) exhaust as well, you might notice a slight increase. Fitting a Fuel X (search UA-cam) would help with fuelling, by making the fuel/air mixture richer. You will never get over 73mph as the ecu has been restricted to that speed. Hope this helps.
They run very lean due to emissions. Free flow filter will make it leaner. Not good. So then you need one of those fuel commander things. Hitchcocks love all this. Ker ching.😂 you are still welcome to try my 500. Can never make up mind which I prefer. Longer rides 350 less tiring. 500 is full classic ride. Noise. Torque. Tiring after an hour 😂
Sounding pretty damned sporty there Ian good mod even if it's only that but I am sure it's only going to enhance the power delivery too good one despite the minor irritations that these insignificant twits provide one with every time one goes out 😉👌👍
So sad this product has sold out :( , hitcook told me this open cover will be re stock in few months. Is there any other way I can buy this product (from other shop.... or somewhere else) . I'm wondering can the DNA cover filter stage 2 fit with stock air filter Mr Ian?
Unfortunately, not having the DNA filter or DNA cover, I don’t know the answer. I have just had a look at the description of the DNA cover on the Hitchcock’s website, and it suggests that it would fit with the standard filter. My best advice, would be to drop Hitchcock’s an email asking the question. It does look rather expensive though 😳
@@ianhughesroyalenfield hello, hitchcock told me the DNA cover filter can work with air stock cover. After ordered and tried DNA cover, I saw that it doesn't fit as the stock cover but good enough (fit around 98-99% compare with the stock). This mod can also work with the meteor 350 (they use the same air filter). So far - so good, Just quick update, help this information can help someone else 😁

You could well be right, but it didn’t do any harm letting it tick over. 😉
Hi! Loved your clip! Question: how has the fuel consumption changed after these 2 mods? Thx Bernie
Hi, thanks. It hasn't reduced noticeably, but then I don't really keep an eye on it. Sorry I can't be of more help.
I feel it makes the bikes more willing to rev in the gears and pick up is better, more torque when climbing hills
Hopefully, I will get out later this week, possibly aiming for some hills to try it out. Cheers
Great that, think I'll invest in a de cat pipe 👍 already got the DNA filter kit .
The Hitchcock’s de-cat is really good quality. Just a tip, allow a bit of the gasket to protrude from the de-cat pipe at the down pipe end, so when clamped up, it won’t shoot inside the pipe (as I found out 🙄) 👍

Does this air filter harm the engine in long time or any issues will occur?
I wouldn’t think so, as the original air filter is still there, and when the outer cover is closed, it is a kind of sealed box.
Would it have a big impact on the output if I only changed the open airfiller cover?
That’s what I did, and no. It does let the engine breathe a tiny bit better, but there is quite a difference in intake roar. I ended up putting the original back in place.
