One of the many doubts ,
I have been using UNI pods on my cafe racer bike and every year they dis integrate , the RED layer wears off in few months and then the second stage black foam pod also tears off ..
I dont use my cafe daily and mostly in summer , so she's parked a lot of time , and I don't oil the filters , so that is the reason they go out of shape ?
I had been holding the K&N POD filters for long and heard that they don't work well due to metal plate .... is there anything we can do to make those work ? like adding some extension between carb and filter ?
I don't want to replace UNI Pods every year : (
Cheers.

you leave your bike outside, dont you? Ive run unis for many years no issues. but i don't store them outside. that being said... run a y boot and k & n of you have to stay away from the hard backed ones... and , fwiwi, they don't really hold up that well either.
IF you have to leave it outside, cover it. IF you have to try hard backed filters, make a 2" or so runner between the bellmouth and the filter neck.
are you running genuine unis or something else?
No SC she's parked in a stilt parking well covered ... I don't oil then so they go dry ? And disintegrate?
Just don't find a reason why in a year they go bad ..:(
i never oil mine. i get 5+ years out of them. usually more.
Wow that's good life , do you oil them or run then dry ?
i never oil them.
:( may be coastal humid weather then here in Mumbai ..
For now I'll replace them though as they work well !!
Cheers

im sure the coastal environment is mostly to blame then. its rough on everything. :twocents:
Mine last forever as well, dont oil either. I wouldnt think it would just be the weather even tho its notoriously hot in India. The sun is also usually hard on plastics but they are covered mostly.
Maybe something is in your fuel that is not in ours and whatever blowback you get is eating them? Or maybe you are not getting the real ones

Fuel is a valid point , possible ....2 sets I got from usa so I think they are genuine ..
I am runin premix ...
You could try some Ramair filters from the UK next time.
+1, if you are doing it every year, you could try just about anything as long as you are not losing pistons and cylinders. Sock on a gutter guard?
The humidity + salinity is the culprit.

Yes I'll try RAM air ....i do have k&N Pod filters which I bought back in 2009 in usa but never installed reading the reviews ...those seem to be solid ones for Mumbai weather ..
It's the humid and salty sea level air :(

Yes and the chrome also doesn't last more than couple years of you don't coat it with grease in monsoon which makes the bike look like shit when u ride in rain n muck on the roads
I run a ton of Uni filters on bikes, mostly dirt, but a Ramair on my RD. Never experienced my filters disintegrating. I do oil them with Fab 1.

I use cheap foam pod filters from ebay and UNI, I oil them and they all last few years so far. I find the cheap ebay filters clamp better on the carb because they have a smaller diameter. I also used k&n pods in the past, they worked fine too.

Wax the shit out of your chrome. Regular carnauba wax. (Turtle Wax). With no grit is important. That works best on chrome.

Any specific turtle wax ? I see many turtle wax , liquid , finish rubbing compound , super hard shell finish , etcetc ....advertise for car polishing ..
These wil do right ?

I do have similar experience with UNI in India. I feel its the humidity that eats up the thing. won't last more than a year and a half max

I run both.
K+N's from 1984 runs so much better.
Uni's still good since 2014.
The KN's are with the big flat chrome back and are perfect.
I switched to UNI just for the 15 degree angle.
cliff
so... what is the theory on these K+N's?

As it was explained to me, the chrome back can cause an unsavory reverberation, or something to that effect. It was in response to me considering a pair with a 4" diameter filter and 2" depth. I needed something to fit within the frame and the carbs.

Yes I also have same knowledge or review on them which I have heard and read so far
ive hear plenty claim they worked well.. but the unis will 99% of the time work better. depending on the distance the hard back of the filter is from the bellmouth is where the difference is. if its a LONG filter, usually the wave wont cause any issues. but you cant fit really long ones on most rds. hence why the unis are used or a y-boot. :twocents:
While living in Houston close to the ocean, my UNIs lasted 3-4 years when oiled on my RD400. It was always kept in a garage. I haven't installed the new UNIs I have for it now that I live in Alabama..

Thanks SC .... WILL A 10MM REED SPACER Make any difference ?

I think my issue is the weather and also my bike is not kept in closed garage but undr a stilt parking and I use them dry
I am going to order new ones and til then am going to experience K&N Pods and see how she goes : )
not really. its the effect the reed closing has from the carb back.

Ok I thought if we can increase the distance between the metal plate at the back of he pods and the reeds it may help reducing the effect ...
its been tried. for decades. doesn't work.
Ive heard people say their bikes (rds) run 'great with k&n pods' right on the bellmouth of the carbs. well, ive ridden enough other peoples bikes to say.. nope. they really don't. there usually a huge flat spot somewhere in the power. the reply usually is 'they are all like that'. no, they aren't.
so, i think it boils down to really knowing what its supposed to run like. amazing how many people don't have a clue as to what a solid baseline is supposed to feel like.
Im not sayin that's the case here. Just offering a theory as to why you see so many on bikes, particularly 'boutique' builds that rarely go over half throttle and just get putted around on.

Try oiling the next set of foam filters you get and see if that helps protect them from the elements.
