Beer Can Air Filter

    So I am riding my motorbike to work this morning in light traffic and, boy, is this thing running great! The engine just keeps getting better and better - even after thousands of miles!

    After my full workday, I give the bike a lookover and - hey! - the air filter is GONE! Ha!

    So I rode the thing home, stopping along the way at the hardware store for some 4mm screws.

    I've been amassing styrofoam pieces lately and I dug up some foam that came in the packing of my newest bike helmet. Quickly searching through the archives of I saw an example of a beer can air filter. I can do that!

    So I drank half a Pabst Blue Ribbon, poured out the rest, then cut the two ends down to around 1/2" thickness. I drilled small screwholes 1 1/2" apart, and I used a tiny drill bit to drill a bunch of little holes in what did serve as the bottom of the aluminum beer can. The foam filter was sandwiched in between the two end pieces.

    Screwed the thing in there and it works very well! Takes up less space than the stock original one.

    Poured the rest out? What a waste, Pabst is a good beer.

    That's a nice and creative way to do things, and you've got a good excuse to have a beer before you start working. I might do something like that just on that basis.

    Dragons Milk, but alas . . . only in bottles. Gotta love the creative mind. Well done!

    Gobisox, that old beer we grew up with here AKA "Falls City" is long gone. There's a new craft beer outfit that produces beer under the name of "Falls City" but it is a much different animal from the one in the past.

    The PBR can I used was a "Tall Boy" - I just couldn't drink it. About a month ago I had a battle with a bottle of whisky and the whisky won. My alcohol intake has dropped precipitously since.

    Took a quick zip down to the supermarket on the moto and the beer can fix is fine. But, I tell you, the engine never ran better than when it was free from the air filter assembly altogether.

    My beer can fix is OK but I want to do something a bit cleaner. I think I can do something with a 1 1/2 inch PVC cap - maybe even glue in a few 1/2' PVC elbows to improve airflow. Lowe's doesn't have an appropriate replacement for the air filter I lost, but they sell a bag of generic air filter material for about $5. It would be smart to have a couple on hand in case my beer can falls off - even though I used thread seal!

    Yet another great reason to drink beer from a can. They make good muffler end caps too. I have made
    a lot of shims with them.

    I've made shims, gaskets, all sorts of good stuff out of cans of PBR

    PBR has been bought by a Russian beverage company. There goes another one.

    Complete misinformation brought on by sensationalism. What actually happened is a Russian-born American citizen named Eugene Kashper bought Pabst Brewing Company for an American company called TSG Consumer Partners. Kashper used to be chairman of Russian company Oasis Beverages (which formally was seeking to obtain a small nonvoting stake in Pabst Brewing Company) but has since moved on to bigger, better, more American things. Between being born in Russia and formerly having ties to a major Russian beverage company, people assumed he was buying it for a Russian company and that's the information that hit the news first.

    Pabst Blue Ribbon always has been and always will be a distinctly American product. Besides that, with the current political climate in Russia, with all the American sanctions over their treatment of Ukraine, what good would introducing such an American product to that market do?

    You can't always trust what people tell you, especially when they're being paid to tell it.

    Butre, thanks for the info. The hipsters tend to like the craft beers but PBR still has that super cool cheap beer status that hipsters will make room for.

    Of course, these same hipsters will not be seen rigging up a motorized bicycle!

    I am glad that PBR is still red, white and blue!

    You never know, motorized bikes aren't a far cry from top tank mopeds. I came in as a straggler from that scene and I can tell you there were a lot of mustached and tattooed 20-somethings from Portland in that group.

    Cool and cheap.
    If you want a better looking performing air cleaner SickBikes has a couple.

    They have metal elements, to clean then just soak then in some Dawn dish soap and water for awhile, rinse it off, and let it dry.

    As for PBR it was the better tasting of the cheap skunk beer until the Yuppies thought it was good.
    The price went up to Bud prices and that was enough for me.

    I don't drink much beer these days, just an 8oz can of Bud for things that require beer be the beverage like Pizza.

    Yeah, now that PBR is sold at a premium price point I mostly drink Mickey's. It's smoother and has less adjuncts to it anyway. Plus they come with those puzzles under the caps

    Damn! Maybe *I* am a hipster!

    Here's a pic of my beer can air filter. I have since removed it and trimmed it into a neater unit. beercan.jpg

    I like that SBP air filter unit. Maybe I shall buy one.

    Had a major malfunction on my commute home today. This is a toughie. More on this later.

    Thanks, guys!

    The SBP standard filter is what I run, it looks great and the fit and finish is excellent. I used to live in W. KY. back in the day, they had Falls City, Cooks, and Sterling (in the big mouth bottles, like Mickey's) alas, all gone! Now, I drink Schlitz. (owned by Pabst)

    Sterling was nasty! Vile! PBR is pretty good beer, especially at $1 a can!
