Not pleased with K&N Air filter!

Thats a good idea. Try a Toyota 4runner early 90's air filter.

 

Sorry buddy I have to disagree with you and the K&N being a POS....no video=it didn't happen. Im proper cleaning techniques could lead to failure.

First off I"m not discrediting your claim. Just saying that you could of been the few that had a defective product. My K&N came from 2 owners ago....back in 2008, the first time I cleaned it, it hasn't been oil since installed. It held up pretty well even after my trip. I have video for it too...

Nice car! I have had my K&N on the same bike as yours for over 50,000 miles. I have re-oiled a few times, with no issues what-so-eva. My velocity stacks never had dirt or grit in the tray either. Recently, I did a carburetor over-haul just for PM sake, new float needleds, gaskets, etc. I have to say, all the brass parts were clear and the neat part was that the bowls were immaculate, seriously, maybe one bit black shate in the bottom of one of them, but that was it. So, based on that, and your observations, I would go with a K&N over other competitors for any other bikes I own down the way.

Video age is crazy shit huh. You can watch everything. Nice going! ; )

 

The reason you had oily dirt stuck to your carb openings are common from over oiling. It takes very very little oil to make the filter work properly. Many over oil. Then the oil will get sucked in and get deposited on the carb entrance. Then over time fine particles, tiny micron dust, will collect and look like the filter isn't working. ALL filters pass tiny micron particles because they come with the air being sucked in. Stuff you can't see and doesn't hurt the engine.

I've seen that from when I first used them and over oiled them even though I thought I didn't. You just have to get educated about how to oil them properly. Most like you don't. After doing it correctly I've never had any dirt on the venturies of any of my carbs afterwards. What you may call a little may be still to much.

Norcal you said the test was done with new filters. So how does your test equate to very dirty filters?

 

I use the K&N oil which is red. Haven't tried anything else so I don't know.

braceyoself777 your video speaks volumes even for kool-aid drinkers.:drinkers:

 

Not likely, as it was the first service to the filter, and the filter came pre oiled from K&N. I believe it's a design flaw. There design causes holes to form in the folds of the cotton. If they used a wave pattern instead of a steep Z pattern, there would be no weak/thin spots in the cotton weave. If you look at your K&N, you'll see small holes in the folds, but no holes in the flats.

I understand there trying to get more surface area by using a Z pattern, but I feel there compromising some filtering in doing so. IMO.

 

A retest of the BMC after 6k miles showed no drop in the filters effective air flow. I never retested the K&N as I was totally unimpressed with the flow characteristics out of the box and never used it. My choice was performance based, as maintenance has never been something I have slacked on. Routine inspections of the filter and airbox never showed any dirt past the filter.

FWIW: the BMC was cleaned after the retest at 6k, again after the engine was worked on and the airbox was insulated at around 9k. The bike was sold before a third cleaning took place.

I have attached a pic of the airbox, the snorkel was removed and the entire flapper assembly was removed.

Dont need the money, and I've had more then my share of that-a-boy's. I'll let you run with this one! Knock yourself out.

 

Wonder what kind of filters the heavy hitters use on Baja 1000 bikes?

 

Is the silver stuff for heat? I got a little carried away with my air box mod. The bike sounds Fantastic with an open box.:wink:

 

Wow.

Yes, it was for heat.

^^Same here, without the right jetting it causes more harm than good. I put my snorkel back on...

 

Bike runs great! No after fires or back fires, and power wheelies in second and will raise the front a few inch's in third under full power. and I'm at 250lb in gear. Plus when I ride in the hills, I'm 90% of the time between 5k and 9k rpm. But I'm thinking of a PC5 with AutoTune.

 

Best of both worlds right? hahahahaha

 

I live in the panhandle where every square mile is pretty much plowed year round for cotton. Doesn't take much of a breeze to start a sand storm here. It's nice being sand blasted daily.

It sucks royally when it's all over the road and the vehicle's tires in front of you is throwing it up in the air for you to ride in.
