Link Here for Filter and filter cover amzn.to/3Zs1w38 As someone rightly mentioned , the cover I took off seems to be a non OEM one anyway, but it was still a OEM airfilter, thanks for mentioning that because I did think it looked a bit "open" ha! Hope you enjoyed the video and Thanks for watching.
I didn't quite see the filter cover when you removed it but the standard OEM Cover has a trumpet on it with an opening of about an inch. Effectively the air enters this trumpet and then turns through 90 degrees before entering the filter and air box. With the DNA cover the opening is around an inch larger and air enters into the filter directly. There are a number of replica filter covers on the market and some owners have modified their own, the DNA filter itself also provides increased air flow. Some people suggests it makes the engine mixture run leaner, no it doesn't, the ECU has capacity to compensate for that - if it didn't you would have rough running issues, EML Light problems and it would eat Spark Plugs. The increase is noticeable both on inclines and makes overtakes a little easier with the increased throttle response. DNA has invested a large amount of money in developing this filter upgrade and from memory their Dyno figures suggests it gains another 2 BHP at the back wheel, not to be sneezed at when you're starting with such a low output in standard spec. Their is also a noticeable increase in torque which shows through when performing overtakes. As for fitting the Fuel X, I wouldn't bother. Owners report little or no difference in performance. I'm on my 3rd Meteor and have fitted the DNA filter to all 3 of them, it's one of the most cost effective upgrades you can do to this bike, as for the increased induction roar, you get used to it.🙂👍
Hi Steve. When you took the side panel off, it looks as if, it’s already ? Had the Hitchcocks open cover fitted. Which is half the price of the DNA cover. The original cover is snorkel based, with small opening at bottom right corner. So your findings would be slightly reduced, due to it already having the open filter cover, with standard filter. But good that you was able to feel the difference. Which is a win win!😊
Had a DNA filter in mine for over a year and it does increase the noise and give a boost. If you're going uphill on motorway for example it has a tendency to hold the speed better with less drop off on power. Well worth it.👍
Every bike is different, seems that the Royal Enfield must have been quite restrictive so it's a nice upgrade! Good to watch the installation being shown, helpful for others.
@@exeterrider Most people do, my heel doesn't flex enough to use it, also I kept hitting it when my foot was relaxed on the peg. It's good to have options.
If you feel it benefits from the upgrades then great. I fitted a DNA filter and a booster plug to my old Interceptor. With the induction roar it definitely sounded better but I i couldn't notice any difference in performance. I've recently fitted a booster plug to my T100 to smooth out the previously snatchy throttle and its help a lot.
That was quite erotic you rubbing that chain like that with that rubber glove on Steve😂😂😂😂 If I want more power, I get a bigger bike😂😂😂 Glad it seems better 👍
Well worth it Mark. It's a game changer. The bike came with a de-cat pipe, but i took it off....it was stupid loud!! No baffle either just straight through....you can have it if you want, I'm going to skip it anyway so its youres for free if you can pick it up.
@@exeterrider wow seriously thanks for the offer but I'm to old to have a no baffled very noisy bike but thanks again for the offer. I will definitely do the air filter upgrade. Take care and see you soon Mark Ps a great idea for a video would be one of those emergency cable repair kits 👍
Hi mate the air filter cover you removed was already an open flow cover maybe a Hitchcock's one the standard one has like a really restrictive trumpet looking openning on it so can't see how it's made a difference by just fitting the DNA filter and cover ? A difference can be made by just fitting the more open cover and keeping the standard air filter
Hi mate, yes I know, I thought it was a bit off when I pulled the cover off but kept going for the camera haha. The DNA filter is 80% less restrictive than the OEM filter, its the OEM air filter that clogs things up. Big difference : )
Brick work here is shocking mate...I got left with the house the apprentice built, it seems to have been repointed years ago, they chopped out about 5mm. I made it worse with my first bit of brickwork there, hence the multi coloured swap shop look.
0:14 Mmm I don't think the statement 'a lot more power' is quite accurate, it improves the mid range pick up and throttle response, but any power increase is moderate 😊 the holy trinity of upgrades for the J-series engine is a de-cat pipe, the dna performance air filter and cover, and the fuel X lite to richen up the fueling 👍🏻
I have a De-cat but it was a straight through with no baffle and it was just too loud. Not sure I'll bother with the fuel x...but you never know. Thanks Kev
A good way to remove the weak mixture restrictions imposed by Euro 5 regs. Booster Plug does the same but costs a lot more. You may find your fuel consumption increases a tad but at the mpg you're getting it will be hardly noticeable.
I haven't looked into booster plugs as yet. Euro5 does more damage than good I think. All rules and guidelines these days that gives someone a job .Thanks Jim.
@@exeterrider You're right, ER. A constantly lean mixture will accelerate engine wear and eventually cause damage to valves and pistons as well as causing excess engine heat. In an effort to overcome this problem manufacturers have had to generally increase engine capacity. The crappy ethanol fuel doesn't help either.
@@kenbrooks7794 Helps with fuelling Ken, for example, my beemer sometimes "surges" a lot, but a booster plug softens all the via the ECU....I think thats right anyway.
At 4:18, the air cover on is not the factory fitted cover. Yours already has the DNA cover fitted. The cover is what makes the biggest difference, (that and a couple of thousand miles to loosen the engine). I’m at 3,000 miles now, fitted the DNA cover at about 1,200 miles. Immediately noticed a difference, not arm wrenching, but better. At about 2,000 miles I removed it and put factory one back in, just to see if the difference was psychological and noticed its absence through subtly less power, it has been back on ever since.
I think I'm happy where it is now tbh....I'm not sure they do a camshaft for this one but its too much of a change for me tbh...so will keep it simple : )
Hi ER, have you considered putting a DNA air filter on your Nc750x, I’ve got a SP engineering exhaust box on mine, and I have de cated it as well , I’m thinking of putting a DNA air filter on it to complete the air flow, (I don’t think there’s anything else I can do to improve it, I did it on my old bike and fitted a booster plug as well (NT 700) it did make a difference, the booster plug is a plug and play electronic device, that smooths out the snatchy throttle, and obviously, the DNA filter gives a better air flow, which is why I’m looking to replace the air filter. Cheers. 😎🏍👍😁
@@roberthallas349 You have me thinking now...Not sure, maybe later next year. It's a bugger to get to the air filter though. Maybe ........the booster seems a good plan too. ummmm....I'll have to research that...good shout : )
The Meaty was looking good in this one Steve ! Nicely shot maintenance video too. I do my chain lubing the same way. I hate spraying crap all over my bike so prefer to do a hand job with a nice smooth glove on 🫢 As you know, I have to keep my Buddy standard until the first MOT is done, which will be next May. After that I will look into getting some Hunter springs and then, if I get bored, maybe do this. Although I do worry that it will result in higher fuel consumption as the ECU adds more fuel to adjust for the increase in oxygen coming in. Being tight, I'd rather burn less fuel than burn more for a little bit of added grunt. I'm sure you'll let me know how the fuel consumption is working out, post mod 👍 Cheers Steve. Nicely done. Always enjoy a tour around Exmouth with you. The place has changed a lot since I went there as a kid ! Love to the crew, George et Jacqueline in France
Thanks George, This was shot in Barnstable . Yes that will open the flood gates once you get that MOT done. lots to look forward too next riding season. Its all worth doing the they hunty shocks is the best mod for me personally. Have a good day matey Outro in
Using the mpg calculator on Google search, I get between 90 and 100 mpg depending upon how I ride. 40 miles an hour everywhere in eco range tops 100mpg. 70 miles an hour prolonged gives me less than 90 mpg. I have a side pannier, top box and a few more bits and bobs too and I'm on the heavier side of masculinity 😅

Thanks Jon, good info there, Yes I'll leave the fuel X....its only a 350 after all. Hope your enjoying the Guerilla : )
Nice post, Great mod especially with the decat pipe, that is all you need, I also fitted fork gators and it transforms the look of the bike
Yes I have been thinking about gaiters too : )
the hunter has already got them.
I could be wrong but I don’t think the filter cover already on the bike is the standard filter cover .
I believe your right , I'm sure all the J platformed bikes have a more restricting air intake that faces down and backwards.
This is true
That did Cross my mind, thanks for confirming, I thought I was going mad.... Shame I bought a new one then 🙄
@@exeterrider I will get down to your manor in the next few months so we can compare, am about 90-100 mins from ya!
The first time I've ever seen that method of applying chain wax👍 Replacement of OEM airfilters with a DNA or Sprint filters is almost always better.
Ive never done it on any of my other bikes before ....I'm thinking of doing it on the NC next : )

If you're going uphill on motorway for example it has a tendency to hold the speed better with less drop off on power. Well worth it.👍
100% mate , Thanks
I imagine it's the engine management system reacting to increased airflow by richening the fuel mixture which gives the improvement.
Yeap that makes sense 👍
Well worth doing👍
Thanks for the heads up on it Dave

Thanks, A nice easy job too...Yes Euro 5 really does strangle these bikes.
That was the first thing I changed on the Meteor; second thing was to get rid of the toe-heel shifter. Much more better now.
I now like the heel toe now tbh 👍

Just waiting for you to do yours first then I'll do it 😎😜
Rumour has it, that it's the cover and its better air flow that makes the biggest difference.
For sure but doing both is best...I had the cover it seems but the difference when the fllter was changed to was massive!
Good vid. Definitely need to do that 👍.
Also are you running the de-pipe? Or did you take it off?

It's nothing for how it makes the bike feel, the engines happier and so is the rider 🏍️👍

It's a brill mod, yes it had already been changed for sure.
The old filter struggled under load.. Good to hear it made a difference for you to 👍
How often do you clean the filter?
Don't know the official time TBH, but if its like a normal filter then every 12k or so its worth having a look and seeing if it needs a clean.
Are you considering the camshaft and/or less restricted exhaust ? If so will you get Power Commander or FuelX boxes? Or does your ECU map that far ?
I’m feeling the Bullet 500 really needs something to help the mapping even without the race cams. But haven’t got round to any further surgery
I think I'm happy where it is now tbh....I'm not sure they do a camshaft for this one but its too much of a change for me tbh...so will keep it simple : )
