Best powersports air filters according to redditors

I've been at it since 2001, and I rarely clean anything.

I keep my humidifier tank rinsed out and replace it when it looks like it needs to be replaced. Every couple of years.

I put an intake filter on the back of the machine. I buy sheets of fine filter foam and cut to size, replace when they get dusty and a quick rinse doesn't seem to do anything.

I put an inline filter between the hose and mask. I change it when it gets gray. Usually about a month, but it depends on whether it's dusty in the room, or windows are open, or its pollen season.

The hose I'll rinse out occasionally, replace every few years, or if it gets cracks or holes in it (cats!).

I use wipes to wipe off the oil around the nasal prongs. I replace the prongs when they stop sealing even after washing with a little soap and water.

Unless you're living in a really bad environment, it takes a lot less cleaning and replacement is a lot less strict than the medical supply companies want you to think--they want to put you on a set-it-and-forget-it replacement schedule, particularly if your insurance company picks up all the costs.

Mine doesn't, I have a high deductible which I haven't met in years, so I just take care of my supplies myself. The best thing I did for my sleep apnea was to lose weight. I still need the machine but it's not nearly as dire as when I first started out.

Good luck to you!

I would go to ex500.org and register on the forums first. Anyways here's my top mods:

• Replaced clutch springs with stiffer ones - this helps at higher RPMs because the stock ones start weak and get weaker with age $10.80
  
  
• Replaced rear shock with stocker from a new gen ninjette because it's a lot stiffer and raises the bike a bit $49.99
  
  
• Removed the pair system because it does nothing good and with exhaust it makes popping noises $15.00
  
  
• K&N air filter installed and drilled 4 Half Inch holes in the left side of airbox $49.99
  
  
• Airbox mod requires carb tweaking so I opened up the carbs and rebuilt them for reliability $45
  
  
• Got some shorty levers 36.99
  
  
• Replaced stock ignition with Coil on Plug type ignition for an '08 ZX6R - prices vary but i got mine for 40 bucks including harness.
  
  
• New sparks gapped at .30" $8.10
  
  
• Higher quality front brakes $32.00
  
  
• Oil changed to Shell Rotella T $19.16
  
  
• Avon Roadrider tires big upgrade over stock. Prices vary I got mine for 350 installed both front and rear
  
  
• Best for last: Racetech .90kg/mm springs with gold valves $300
  
  

Run it without the air filter. If it starts and runs OK, buy a new air filter and apply oil as directed (if it uses oil, some foam types do and some don't). Over-oiling can clog the filter and make the engine not run well if at all.

You could full bad ass and connect up one of these

Not significantly. It's sheltered, and even in heavy rain isn't going to attract much when riding. A little moisture getting through isn't an issue; it flashes off in combustion.

​

I've had bikes with pods, even ones living back in Vancouver and riding year round, and it was never really an issue. Your legs shelter from the sides, the engine from the front, the bike itself from above. If you're submerging the bike, well, that's a problem no matter what. But general rain isn't really an issue.

​

However, if you want to go aftermarket airbox for additional airflow but don't want the exposed K&N filter the Hordpower uses, you can get the DNA kit which performs comparably: https://www.amazon.com/DNA-Cover-Filter-Yamaha-MT-07/dp/B07DW3TDF4

It is an '82 XS400 special. It ran from 77 to 82. I have drag bars, but left all the cables the original length. The horn bracket got flipped upside down so I could access it/install a new one. I made a bracket that attaches to the bar running down in front of the engine to hold to LED fog lights, run by an auxiliary switch. Painted and wrapped the headers and have emgo shorty mufflers. Emgo pod filters, and a puck-style filter for the breather tube nipple. Led tails, led indicator lights, Upgraded headlight. Point of note on the headlight, mine was a sealed beam halogen. So to add a new bulb you have to buy an aftermarket reflector housing from candlepower.

EDIT: Also forgot Oury grips, cafe mirrors, new fuel lines, fuel filter and vacuum tube.

whats the type you get?
I just did some googling, I think something like this:
http://www.amazon.com/Uni-Bulk-Fine-Foam-Filter/dp/B000WJJA0U
is what I'd use.
The filter material I'm thinking of is very course, you can pretty much see through it. But servers that have been running for over 4 years with these filters in very dusty environments have kept running fine, (and the inside of the server is clean) but I need to wash the filter out almost every month because it will be caked with dust and dirt.

The other thing I've seen is these:

Man, a 125 down on power? That's a hard life!

I would ditch the box and get this OR this

I can't find if your carb is Constant Velocity type though or not. If it is, a pod filter WITHOUT rejetting is a bad idea, and CV carbs NEED metered air to go into them, and the box meters the air. But pod + rejet = more power sooooo take it for what it's worth

Should be a 28mm intake, but you might want to measure just to confirm.

Cleaning the fuel tank = draining out all the gas. it hasn't sat for SUUUUPER long so just getting rid of the old gas should be enough. Once drained, pour in some new gas, slosh it around, and drain that out too.

An example of a helpful comment from someone else here. Take a lesson.

I have no issue,being,told im wrong. But it needs to come with being shown the error in my ways. As you can see, this guy showed me that the filter can be had cheaper than I thought instead of just telling me I'm a cheap bastard.

Bye.

Other guy's post--> Run it without the air filter. If it starts and runs OK, buy a new air filter and apply oil as directed (if it uses oil, some foam types do and some don't). Over-oiling can clog the filter and make the engine not run well if at all.

That's only for the r56, as the airbox is at the rear of the engine bay squeezed behind the engine bay and the firewall. I've heard nothing but good things about it though, I don't think the rain would be an issue unless you were running under a waterfall. They do make dry filter wraps that you could use to prevent water intake if you're super worried though.


Although, i was thinking r53 vs r56s, i didn't notice this was for an r50.

Yup, I determined I had the 69 mm valves before ordering.

I will do all that with the carb tomorrow. I do have a main and pilot jet kit for when the BBK is installed.

I ordered these 2 filters to see which one worked best. Are they considered 'cone'?

Close up.

Stock intake plenum, ABS toilet plumbing (new), 70mm UNI filter.

Any idea if you used the 3/8 or 5/8 one? My engine is currently running a bit rich, that's why I'm looking into this. Figured there wasn't enough air getting in.

I've had good experience with Uni pods. Dip them in a bit of oil before installing and it'll give you a more favorable flow resistance. http://www.amazon.com/Uni-Pod-Filter-Kit-Chrome/dp/B000GZMZKC/ref=sr_1_10?s=automotive&ie=UTF8&qid=1417452486&sr=1-10&keywords=uni+filter
