Pods n' jets

Does anyone have any experience/opinions about Uni foam pod filters? They're half the price of K&Ns.

I have the carbs out and figured I'd go with the pods instead of putting all the stock airbox back on.

While I'm at it does anyone have a good starting point for jets? Currently I have a Mac 4-1 pipe (horrible quality but sounds nice). Main is now at 114 with needle in the middle (three down from top). No idea what the pilot jet is. Mix screws 2.5 turns out.

I was calculating a 125 main with 47.5 pilot while leaving the needle where it is.

If the mack pipe is not a performance pipe you may not have to change anything in the carbs. put the pods on first snd run it a bit. Read your plugs and go from there.
speaking of cheap pods i just bought a set of emgos for about 36 dollars. I would like to know what the difference is between them and the $100.00 plus K&Ns

The main diff I have been told scotty is that they are junk. My mechanic told me that as well as several guys here on the forum have said it. But I don't know that first hand so I am just repeating what has been said by others. But I know that several of them know what they are talking about so that is why I swayed away from getting them myself.

Let us know how they work out for you. It would be nice if there was a low cost alternative that actually worked!
 
Interesting feedback on the filters. To be honest I put a pair of Uni foam pods on a KZ750 twin a few years ago and they worked ok. Granted, the K&Ns are the best available but with a budget in mind it's hard to argue against the price difference.

BTW, the Mac is a 'performance' pipe and flows nicely. It's just a low quality product. I picked mine up off ebay for $100 so it seemed like a bargain at the time. It started rusting after a month! Now I can't decide whether to have it powder coated and keep it or get a V&H or something else... It's ugly as sin but works.
 
i bought a set of emgos and after inpecting them and the k&n i dont know what the difference is. iam an auto tech. i have found thru the years that some brand name parts are more expensive just because your buying a name. the off brand par in almost every case performs just as well.

just my professional opinion :lol: :lol:
 
Thanks for the reply on the filters. I think I'm going for the Uni's just because I'm a cheap b'tard.

BTW, if you're from Venice then maybe we can converge someplace. My bike's in pieces at the mo' but it should be back together soon. :D

I'm dying to hook up with Scotty too....

Ron when my bone yard said why not use the emgo filters, i said i dont use crap on my wheels. Then he showed them to me. It looks just as well made as the K&N I run on my bike now. I took them . From the recent research i have done it seems that these emgo pods are being used on some top performing road racing bikes. ????????????????? well thats what the ads said. They look fine to me. I truly cant see the diference in quality. Who knows??? really who knows????

i didn't know that mack also made performance pipes. Can you tell me about the model numbers or something. when i bought my 1100e it had a mack 4 into 1 pipe and with or without the baffel it ran the same. then i was told by numerous folks that macks were cosmetic pipes with a good sound and not performance pipes.

So whats the story guys????
 
I don't know the model number but the pipe has a nice header and free-flow can. It's a very basic construction but 'looks' like it flows much better than stock. I had a jet kit installed to get the carburation corrected so it evidently provided a performance boost. 'Seat of the pants' feel shows a dramatic improvement but I haven't splurged on a dyno run.

I wouldn't recommend Mac pipes to anyone unless they're on a budget. Like I said before the quality is terrible but the effect/sound is nice.

If anyone else reads this then splurge on a V&H or similar system.
 
is this the pipe you have

and what part is rusting, and can you paint it with some high temp exhaust paint?

My street tracker has a mack 4 into 1. i have repainted it with exhaust blACK SPRAY PAINT A COUPLE OF TIMES. iT WORKS FINE FOR ME.

That's it but with a black can. I've painted it twice now with different brands of high temp paint. Still gets rusty after a year or so.

Maybe I'll just get some of that exhaust wrap and cover it all up. Out of sight, out of mind... 8O
 
You mentioned in your first post, you plan to keep the jet needles in their same positions. If they ARE in the stock position, I would at least raise the needle 1 position (lowering the clip) if your needles are adjustable. I can't tell you how well the Uni's flow but they will allow a lot more air in than the stock air box. In fact, 1 position richer may not be enough, but it's a starting point.
You spend the most time riding on the needle circuit, so don't overlook it. A hot running motor will be the result.
 
The uni's flow pretty well, I had a set before the K&N's I have now. They do not flow as well as the K&N's though. I think the biggest difference is durability though, the foam on the UNI's will degrade after a while. As for the EMGO's, they have a paper element, and are not washable. They are disposable, like a car air filter. Other then that I don't know how well they perform.

BTW, if you keep an eye on ebay you can find K&N pods. That's how I got mine, for $50.

I was wondering about the disposability and cleaning business. no instruction or paperwork came with them. well they wil be good to experiment with using the stock carbs and then ill go for the K&Ns when i use the larger pots.
 
Since I made comment earlier and this is still going around I just asked Paparo why he said that just now since I was on the phone with him for other business. He said this last time and just reinforced it now,

You get what you pay for. The Emgo's are way more expensive than the K&N over the long haul because the K&N are high quality parts and will last almost a lifetime as you can clean them and go again over and over. The Emgo's you basically run until they clog up and then you chuck them and buy new ones. He also said that in the time that he has been servicing vintage bikes he has had to replace several Emgo and other lower cost brand pod type filters because they are either disintegrating or they have actually started to collapse. He said they crush with the greatest of ease. He also said that it is much easier to setup jetting and the like with the K&N due to the available specs whereas the others can be a lot more work to dial in because they do not setup the same as K&N's. He also said the K&N's will flow much better and are more consistent. I asked him what he meant by that and he said that the Emgo's and other brands are known to flow differently from one filter to another. Now that one scares me. 8O

Again, not my words as I have no experience with them at all. I have only ever used K&N and have never had to replace them once purchased so I guess time will be the answer as to if any of this is true or not.

The only thing I would add to any of that that comes from me is that I value what Joe tells me more than mostly anyone else simply due to his level and amount of experience. He is a 52 year old man who has literally done nothing but this his entire life. So for me, I would just never even try them. You know, and I could be missing out because of it so it is good that some of you guys are. I have to believe that they will ultimately work OK as so many of them are sold and I too have seen them on countless bikes

Take that info for what it is worth to you.
 
I picked up what I assumed was a MAC 4-into-1 header on eBay for my 550. Who knows, but I had it sandblasted though to get all the chrome and rust off, then painted it flat black for the rat bike look. The paint was Rustoleum B-B-Q and has rust inhibitors. No rust at all and I don't worry about it. The Rustoleum will get stained by oil and gas drips though so next time I'll spray excellent PlastiKote. BTW, I'm not sure any header makes that big a difference in performance. Maybe a tenth in the quarter-mile according to the tests the magazines used to run in the "heady" days of the '70 and '80s and Kerker and Hooker and RC and Yoshimura and SuperTrapp. But they look great and are so much lighter than stock and with the right meg can sound a lot throatier. About pods, I know K&Ns flow more than Uni's but if the Emgo's are just as good I can't say. I'd appreciate some user's comments.
 
Well, I decided to go with the EMGO pods when I did the Stage-3 rejet of my GS750L. I like the sucking sound that they give though the only thing I have to compare it to is my cars' cold air intake. To me they seem like they will do the job just fine. The only thing i'm a bit concerned about is water intake. If I ever got caught in the rain i'm quite sure water would get in the carbs. Because of that I'm creating a shield to go over the pods so that they don't suck in water but still have open access to air. This shield will also help control the flow of air around and into the pods so as to allow consistent flow through the venturi and allow for good fuel:air mixture. I have never tried the K&N's but if I can ever afford them I will give them a shot just to see how they are.

Ride safe,
Dm of mD
 
GOOD INFO MARK. I WIL GET A SET OF k&nS AFTER I MESS WITH REMOIVING THE AIR BOX AND INSTALL THE LARGER CARBS. I MIGHT HAVE FIGURED THAT THEY WERE NOT WASHABLE.
