[manshack_one]

Anyone have a comment positive or negative about putting these on my 79 1100 Special?

Lots of folks use them. They are the cheapest option. You need to make sure they don't have an inner lip that obstructs the airflow into the airjets. There are apparently to types of these EMGO's ones with the lip and one without. If money is the concern these are your bet. If not someone recently posted of a Legend car site that has very nice dual inlet filters. Oh yeah, you will need to rejet if you are currently jetted to stock specs. Do yourself a favor though and don't start the pods vs. stock debate.

Hi Manshack,

Don't ask the questions; just do a search........ you will be reading for days!

These are cheap... but you won't like them. TC made an adapter for them and made them work, but without some work, they will choke out your motor @ 4500-5k rpm. Also, the filter element just kind of snaps on to the rubber boot lightly and one fell off on me.

If you look at the bottom pic in the ad, you'll see that inside lip closes off the opening considerably and will actually cover several of your air inlet jets on the bell of the carbs. Here's a comparison of some decent ones with those cheaper type.. notice how the opening doesn't close down. Both of these actually fit a 54mm throat.





Here's what they do to your carbs. I took the boot off so you can see...







And here's the little rubber lip that's supposed to hold them on....





So I guess you can tell my opinion of them.. lol. I thought it was a total waste of money, and I paid $40 for mine. The filters I have had pretty good luck with are the ones you see in the first pic. You'll have to call them because they don't list them, but these were $60 for the four at aperaceparts.com They are the cheapest I found for the quality.

One last thing... I think you should be looking for a carb opening size of 52mm... not 54mm. I am wrong a lot, but I think the XJ carbs are the only ones that have 54mm throats?

Just my 4 cents.. lol.

HI, I bought the cheap ones thinking I was aving money. Once I installed them, my bike would not rev over 5000 RPM.
Buy the good ones that do not restrct air flow. You will be not be dissapointed

Or, you can do like I did on a friends bike and just take a Dremel to that lip

[trbig]

I tried trimming that lip and it made the little lip that holds the filter on even MORE flimsy.

To each his own...

I bought the cheap EMCO brand and the lip in question on mine is angled back and does NOT block the air holes. Mine work great. For what it's worth!!

UNIpods

Hi Manshack,
besides the adapter rings blocking off the carb's secondary air intakes, on XS650s anyway (and the XS11 is more or less the same carb) the sheetmetal end and it's closeness to the carb does something technical to screw up the airflow above 5,000 rpm. WTF, UNIpods work on my bike just fine. I have no beef at all with the stock airbox performance, it's that my carbs seemed to need cleaning once a week and I wanted to be able to take them on and off without fighting with that effin' stock airbox for an hour and besides, I was running out of bandaids. So I fitted UNIpods instead. And fitted a secondary carb support to hold the carb rack at the back because the 'pods don't do that. The bike runs fine with the UNIpods and it takes perhaps a minute each to take one off or reinstall it. As a demonstration of McPherson's Law of Dynamic Negatives, ever since I have had the ability to whip the carbs off quickly & painlessly they have not silted up and I have not needed to remove them.

Can you link me to the right UNI's for '79 carbs?

Can you still have room to leave the airbox in there if you remove the boots? Seems like it would look empty in there without that shiny chrome showing on both sides of the bike.

Hey Manshack,

They list the Uni's for the 80+ series, because they are for the 54mm sized inlet bells. But I've measured a set of 79 carbs I have and they also have the 54mm diam. inlet bell, vs. the 52mm size!! So...measure yours, and if they are 54mm, then you can use the Uni's even though they say 80+ models.

This is an old photo of Godzilla with the older Uni filters on, not too much room between the side covers and the filters, and you can check your battery fluid levels easier!

Thanks Topcat!

You're always there to fill in the blanks for me!

I think I'll get a set of these unless by some miracle the carb gods smile on me and I get a perfect bench sync and rejet done in one shot!
