Individual air cleaners?

Bare with me here, I'm a good auto mechanic but new with motorcycles. I've seen a number of custom Kawa fours where the air box has been removed and small air cleaners attached to each carb. What brands are these cleaners? I really like that look, but what is done with the vacuum line that went to the airbox? And is this mod legal in...say, California? Thanks?

dont bother with anything but k and n's......pricey, but worth it....as far as legal in california...CARB probably knows when you slip out a silent but deadly one....i m gonna guess no.....then again, my k and n cold air intake on my car came with a CARB exemption sticker of some sort i stuck underneath hood......

You may like the look, but be sure to keep the stock airbox handy. Many folks switched back after expeiencing a variety of pod related performance issues. Ed

K&Ns are the best. You will need to rejet the carbs if you use them. Sorry I cant help regarding your question about the line to the airbox as we did'nt have that emissions stuff up here in Canada.

Personally, I prefer the Emgo pods over the K&N's. The K&N's cost a lot more and are a pain to clean and oil. The Emgos use paper and are used dry. They are disposable, but are far cheaper. They look very similar to the K&N's.

I've used K&N's for many years, but have preferred the Emgo filters for several years now.

I've also used the Uni foam filters. They were just as much of a pain as the K&N's, but disintegrated over a few years.

On two bikes, I went back to the airbox (as 650 Ed says), and I think that is still the best overall solution even though it is really a bitch to take the carbs on and off. It's much better in case you get in the rain. The filter is way cheaper and disposable. The performance is also a little better for stop and go driving, especially with a passenger, but the pods do have a slight edge at wide open throttle on the highway.

I still run pods on one bike. That bike can't take a passenger and I like the open look on the frame when using pods.

I found the foam UNI's to be the best middle of the road filter if you don't want to fork out $$$ for the K&N's. I beleive when I bought mine JC Whitney had the best price.

My bike runs good with them, even in crosswinds. I have also used the Emgo's and they didn't seem as good.

I also like the fact the UNI's are serviceable. Mine haven't fallen apart yet and I've had them for a few years now.

Not a pod man myself but consider K&N's the best. I have K&N in ALL my vehicles. Bought the one (stock air box) in my 650 for $11.00 back in '80. Have not bought an air filter since. I live in SoCal and you can do anything you want to motorcycles as they are not subject to emmisions testing.
