RE Super Meteor, Air filter Mod

[@motorbikerscosmeticcompany1594]

Can't really see it affecting the air flow very much since the filter box is behind a panel anyway. Bear in mind, this bike is Indian and these guys ride in monsoons, so as the name suggests and given which way it points, the snorkel's primary function is probably to stop water when riding through deep puddles etc. Also, with it being fuel injected, the whole thing will have been set up with the snorkel in place, this could affect any resonance set up. On the bottom probably no problem but might be something to watch for on the top speeds. Nice bike btw! Ride safe.

Your thoughts were my initial thoughts, I’m guessing the induction noise occurs more due to the trumpet effect of the filler being more open at the end plus the metal panel shape will accentuate the noise. All in all without a chip, exhaust and remap I can’t see the advantage of the DNA filter other than the hype created.

She runnig sweet Mike, I honestly wasn't expecting any difference with the snorkel taken off. But just like the Suzuki DRZ 400 airbox mod, the difference is quite amazing. Have a good Christmas mate. ✌️

I’ve just fitted the DNA cover plate, like you I thought the original filter seemed pretty open anyway. I think it’s made a difference too. The only advantage in using the DNA filter is that it becomes a service item, not replacement. Over time this should save money 🤷🏻‍♀️

Thanks Paul, that's great info. I'm going to try taking the cover off on a dry day, although I may have to wait a while for the UK weather!

It sounds way different, I have ridden it a few times since removing the snorkel. Big difference.

That baby sounds healthy! 🏁

The plastic schnorkel is designed to keep the water drops away! Water can easily get sucked into the air intake in heavy rain at high speed / rev. I prefer to keep the plastic schnorkel as it is and use the DNA filter for less air resistance.

@@8ProductionRoad rain is not something we have a problem with here. 320 days of Sunshine ☀️ but yes fair point, but most people fitting a DNA filter remove it. I would love to see a dyno test I’m sure there is no significant difference with the DNA alone, maybe with an exhaust mod. Thanks for the comments, ride safe

[@grenaltuscano9545]

This is awesome i was looking for this same option on my bike as well & was thinking if i should buy DNA filter but it helps me ;) Great info thanks you

[@8ProductionRoad]

The airflow at 5000 rpm will be about 50L/s what is the average of a house vacuum. And is not much, so I wonder if you can feel any pull while adding / removing the cap with the bike running at 5k rpm.

[@motechRevolution]

@@8ProductionRoad I'm not sure if it adds any more power, the induction noise is noticeable, especially on throttle down. I rode with a mate last weekend, his first words were 'Your bike sounds meatier than mine and the induction noise sounds great' It does seem to pick up quicker, but it could be a placebo effect, anyway I like the free mod. Thanks for commenting ✌️

[@DLoneRanger]

I would suggest you try the DNA even borrow one from a friend then you will see.

[@johnrocker2986]

Noise is that placebo that fools bikers into thinking the engine is performing better, but when put underload on a Dyno and the fuel plot shows these K&N or these copy style filters, never flow air like a conventional paper filter as I said its just placebo. Until a modern engine can be forced more fuel, their is NO gain in power.

[@motechRevolution]

That’s a great answer John, I suppose a Dyno is the only way. It would be interesting to do an air flow through the standard filter and say a DNA. I do Think directional flow may influence induction sound etc, it certainly does with plumbing. I run a salt water marine tank, some plumbing tweaks certainly cut flow sound dramatically. Thanks for your comments and input

[@mikeyerke3920]

I’m not a big fan of the K&N style filters. I’ve done a lot of dyno time and never noticed any discernible difference when using them, so I’ll have to agree with you on that. I use paper in most of my machines, including my big block 7.4L Chevy engine, and that thing moves a LOT of air! I do use foam elements in my off road bikes for convenience and the extreme filtering needs that off road riding demands. The K&N filters are greatly overrated in my humble opinion, besides, they are a pain in the ass to clean as well. 🔧
