Any recommendations on what type of air filter I could fit to my 1300 xflow and where to get it from? It's a bog standard carb and I have a hole
cut in the bonnet already! At the moment I'm running the engine with the original filter but it's the size of a frying pan.

ITG or K&N sausage...
Is it really called a sausage?
I was thinking of something like this:

something like that would be ideal!
You cannot get better than a K&N filter in terms of quality and performance.
Only thing that worries me about K&Ns exposed like that is they do not like getting wet. The airflow capacity drops to about zero and the engine won't run if it's really wet.

an umbrella .............
sorry, but i thought it was funny (and it takes your post back to the top!)
On a rolling road my clean K+N showed a 2 BHP reduction over no air filter. The rolling road dude said the Pipercross was better, but really hated the wet!
if it sticks through the bonnet, it'll want cleaning regularly too.
i've done 800 miles so far, and the filter you see above is now completely black, and full of flies/general shite.
it still seems to flow alright, but doesn't sound as nice as when it was new.
i have no screen, so don't drive in the wet if i can help it. it stings too much

hmmmmmmmmm!!!!!!
As most on here know, I race an autograss car, and there is not much that tests an air filter more than running in dust that you can't see
through whilst racing, getting plastered in wet mud, and getting soaking wet too.
I have NEVER had a problem with K&N's when they are wet, though I have had problems with foam filters (ITG and Pipercross) "sucking
in" when they are wet.
The K&N's that we use still flow fine (pretty much 0 restriction) even when covered in 1/16" or so of dirt.
Certainly on the rolling road, taking the (dirty) filter off and putting it on again made 0 hp change.
Just speaking from experience.
BIG K&N, no water probs, no dirt probs

K&N looks better, On a stock carb you probably won't get any extra hp out of it, might sound much better, and has lifetime warranty,

i won't bother washing it then.
cheap as chips!

Two experiences I've had with wet K&N's
1) On a bike I owned that came with the K&N's already fitted. The first time I rode it in heavy rain the bike started a misfire that got
worse and worse. I though it was the HT leads and coil that were tracking, but the black smoke from the exhausts pointed back to carburation.
Pulling the filters off restored full power. I've since heard simmilar stories from other bikers, so not an isolated case.
2) A friend had a mini with a big downdraugh Weber ( DCNF??) and big K&N sticking out of the carefully cut bonnet. Once saturated in the rain,
RPM was limited to about 2500 RPM, above which the engine misfired chronicaly, produced clouds of black smoke and stunk of fuel.
If I had to do this I'd personaly make some kind of shroud in front of the filter to deflect the majority of water away. I guess you could make
it removable for dry weather if you wanted to.
you want a little buldge by the sounds of it, there was a post a while back, surrey dave had one and i think david jenkins fitted one.

All very interesting, but where is the best place to get one like the one in the picture?
EBAY
which picture?
if it's mine you're after, the round one, its a 56-9038, and i got it through halfords. they're £43 iirc, needless to say, that's
not what i ended up paying. it's listed for a 1.6 sierra, but i don't know which carb it's supposed to fit, because it has 2 bolt
holes, and a circular hole about 3" across.
i jigsawed it out to shape, and then stuck it on my carb.
ebay would be a start, but i wouldn't expect to get something an exact fit for any weber carb except for the dcoe variety. i rang K&N and
either got speaking to the office fool, or they simply don't do exact fit filters for weber downdraughts.
hth

forgot to mention, halfords is having a big stock clearance atm, and one of the things we have in dewsbury is an oval K&N. iirc, it's under
£20. can't remember what it fits, but a bit of ally sika'd to the bottom would make a fine new base plate for it.

i cut mine out and screwed it on, ISTR there was an adapter plate involved too. Easy!
