I need to change the pod filters on my Z thou A2 as that's what the bike came with and standard airboxes are too expensive and tricky to obtain. I did try some cheap Ebay versions but they made the bike run like shit at higher RPM (over 6K)... so, it comes down to K&N's (surprisingly expensive at £179 for a set of 4) or the foam Ramair version (better value at £48 per set).

All views and recommendations welcome?

S and Bs are available from Grumpy 1260 (and probably others) for about half the price of K and Ns and work just as well.

I had Ram Airs on my RS34s, you may need to cut out the lip inside to make them work properly, they're a bit bulky which is why I changed to S and Bs.

Ape pods are superb also from grumpy 1260

I use the cheap pod filters on my z900, I have z1r carbs on it 28mm runs better with these carbs but it should run well with 26mm z900 carbs it not the fillters why it running crap, its down to the jets been using cheap fillters for years no problems check your carb rubbers to the head check for cracks in the rubbers

If you are going to Jim's rally at the weekend I will bring some jets with me and I will fix it for you I have most sizes

As soon as I changed back to my original pods the bike ran absolutely fine so I'm fairly certain it isn't a jetting issue. The rubbers between the carbs and head are also ok. So, I think the issue was with the rubber sleeve that connects the pods to the carbs. I think they may have been partially blocking the pilot air passage hole at the bottom of the carb mouth inlet.
Anywho, thanks for the offer but I'm over on the Isle of Wight this weekend visiting some caulkhead friends!

I had cheap pod filters on my ZRX, they looked cheap too. The bike came with 'em on cos it had been converted to monoshock and had no air filter box. It also had a stage 3 dynojet kit.

It used to spit and cough a bit on medium throttle openings. I junked the pattern pods and bought some refreshingly expensive oval body K&N's.

It looked better and ran better. the spitting back vanished with no more changes. The bike has been all over Europe and never missed a beat or lost a pod. Its been caught in ridiculously monsoon-like rain and seen no issues there either.

You get what you pay for .... buy cheap, buy twice

Some good suggestions from the guys. Just be aware that K&N's are intended to be oiled and re-washable while some of the cheaper ones run better dry. Ultimately, K&N's are probably a better investment, providing cleaner flow and longer life. It depends what you need and what your budget will extend to. I guess.

You may be able to trim the rubber lip where it blocks the air jets with a craft knife, I had to do this with Ram Airs
