Another air cleaner question

I've searched through as many relevant air cleaner threads as I could find. I'm looking for some more detail, though. There a quite a few choices and I'm hoping to learn even more.

I'm looking to figure out which one provides the most extra clearance for my knees. I'm 6'2" with a 36" inseam. If I sit pretty far back on the bike I can clear the stock housing but I can't ride comfortably that far back for very long.

So far, I've found the following choices:
Kuryakyn Velociraptor - narrow but very tall?
Kuryakyn HyperCharger - Still big and maybe gimmicky? Looks good, though.
Cobra PowrFlo
Cobra (Plain w/o the scoop) - anyone try both Cobras and have an opinion?
K&N (RK-3940) - seems no smaller than stock
Vance&Hines VO2 - Maybe the smallest but requires buying the cover as an extra
xXx Big Air Kit from SS Custom Cycle - Seems very similar to the V&H
Two Brothers (seems to no longer exist?)
Low and Mean adapter to use Harley filters - Performance Air Intake Adapter for Star Bolt, Stryker, VStar 950 - Low and Mean

I know that there are plenty of riders who don't contact the stock housing, buy I definitely do, and by a couple inches.
For those who do have clearance issues, have any of you found the cleaner with the most clearance? It's hard to tell by a lot of the photos.
I'm more interested in knee space than airflow, but increased airflow would be a great bonus.

So far, it seems like more people like the Cobra than the other options but the V&H seems like maybe the most put together (hate the gouging on the price of the cover plate that should come with it, though.)

The Low and Mean system is more what I was looking for to create the most space, but that seems like a bit of a cobbled together item that feels sketchy to me. However, I'd love to find another 90 degree elbow style adapter. Any others out there that I didn't see?

I don't plan on getting caught in the rain much. I have a KLR for that, lol. It's garaged so I'm not too worried about water getting in and potentially hydrolocking a cylinder. I'm assuming I could find a dry sock for the more common housings, espcially the ones that use a K&N?

Sorry for the long post, but I'd love to get as much knowledge as possible before I drop $250-$350 on this. Thanks in advance.

I'm 6'1" with a 34" inseam. I hated the stock air cleaner from New. I replaced it with the Velociraptor and while I liked the way it looked and sounded, it still wasn't comfortable. I plopped down the money for the Cobra Power Flo and I couldn't be happier. Jevers ⁸

Great info! Thank you! Did you do the full Power Flow with the front facing inlet or just the bare filter version? I don't suppose you have any photos?

I did the full Power Flo with the front facing snorkel. It is one of the best mods I have done, and I have done quite a few. My knee doesn't even know it's there! And the machining on the velocity stack is a work of art. BTW, that is a full Bassani exhaust. I love the way it looks, but, MAN is it LOUD!!!!! Good luck with your mods. Jevers

Thanks for the info and the photo. That's exactly the angle I was hoping for so I could compare the amount of space gained. That exhaust is sexy!

It looks great! You ever consider painting the fenders black?

NOOOOOO! I love the retro look. It reminds me of my 1975 DT400 enduro I bought when I was 14 years old.

I totally get it, and I love your reasoning! I plasti-dipped mine black a few years ago and I really like it, but I can always peel the plasti-dip off if I ever want to go back to that more retro-look. Cheers!

For a while, I was considering repainting the tank and side covers with a retro yellow, white and black scheme, similar to that '75 DT400. I just couldn't bring myself to take sandpaper to my pristine red paint! Maybe I should find a tank and side covers 🤔.

I would never touch the factory paint job but have aspirations of a different colour, can anyone confirm direct fitment of a bolt fuel tank?

Cobra power flow intake is the best preforming one. Most power. I’m 6’3. No knee hitting. I think I it looks great. Get a Ivan’s tune with it. He was the one who recommended it to me.

Great info. Thank you! I do intend to get an Ivan's tune. Perhaps over the winter. I'm pretty settled on the Cobra at this point.

I really like it. You can hear it sucking in the air! Ivan also recommend to me the slip on freedom performance combat exhaust. Best sound and performance.

I've looked through as numerous pertinent air cleaner strings as I could find. However, i'm searching for some more detail. There a many decisions and I'm wanting to learn much more.

Well, I've ordered the Cobra PowrFlo based on a number of recommendations. It should arrive this week. I'll do a write up of it when I get it installed.

Lockheed, how did your Cobra PowerFlo work out for you?

So far, so good.

The installation was very easy. All the parts were correct and the instructions were very accurate. It clearly flows more air than the stock unit but I haven't had the ECU reprogrammed so I'm not seeing any power gains, though I think I saw a very slight bump in gas mileage. It's definitely louder with a pronounced intake "honk" at large throttle openings.

From a space saving perspective, it frees up room at the knee, which is what I was looking for, but not as much as I would have liked. It's very smooth with a rounded rear area so it's not rough on the knee when you do contact it.

There is, however, a plate that mounts above it to protect the EFI wiring and whatnot and that plate has hard, 90 degree corners on it that my leg sometimes contacts. It's not necessary, functionally, and I might remove it. Here's a picture and you can see that I'm already wearing the finish off the corner of that guard. Overall, it's an improvement but a pricey one. If I do flash the ECU it will be worth it.

It would have been helpful if the wiring protector plate was rounded too. Thanks for the report. Very helpful.
