I see so many posts about rejetting and lots of trial and error work to get the carbs tunned right to run with pods.... and it seems like much of the time it is done simply for the better look of the pods on said machine. Has eanyone ever thought about trying to tune the airflow through the pods to match the stock carb settings? maybe a layer of filter foam inside the pod filter or a simple restricter plate in the mounting boot? I am looking at possibly having this same problem on a future project where I want the pods for the looks. so I thought i would throw the idea out here for discussion.

I have an old Henry Abe "bread box", it tunes a lot easier. I've been trying to fins time to design a new one.

I have seen the bread boxes, but didn't really like the rectangle shape for my kz1000 project, I have a plan in mind for an oval shaped filter box that I will try to match to the stock carb settings. but later on when i get to rebuilding my kz750, I was thinking about going with pods and trying to tune the airflow to work with the stock carb settings. If, however, I can get the oval one for the 1000 to work right, I might just build a similar one for the 750.

Some folks have reported that installation of a Dynojet kit designed for pods, which includes a different jet needle, helps significantly with carb tuning where the stock air box and filter have been replaced with pods.

Good Fortune!

I love pods. Bought a nice 79' KZ650 for cheap last November. Guy cut out the airbox and installed pods. After about a year of trying to tune he gave up and sold me the bike for cheap. I have 4 more 650 airboxes waiting for bikes with pods. BTW the 650 is now running like new and I'm in talks and about to triple my investment. The orig owner wanted to buy her back but I won't sell to a butcher. Don't know what else to say. Keep podding those puppies!

An airbox is not just a restriction, it is a contained volume of air, with mass and momentum and pressure, and some restriction. You won't be able to replicate the physics of that by simply restricting a pod filter. When you use pods, you tune for pods based on their physics.

You can make some noticeable power gains with pods, and if you can tune them properly, the bike is every bit as driveable as with an airbox. It depends on how much time and effort you want to put in to tuning. A wideband o2 setup makes it much easier. CV carbs will take longer, but can still be done.

A wideband o2 setup makes it much easier.

Z-650-Spirit over at the KZ650.Info site posted a writeup w pics for tuning a 650 with an oxygen sensor.

The dynojet kit seems to have worked well for me.

Until a big truck passes or you get hit with a stiff crosswind......

I ride a lot and this has yet to happen to me.

Just make sure the bike it running great before you make the switch, my big mistake was changing to many things at once and then having to chase problems.

Why would a big truck be passing me?

I tried that but could never get the material to stay on the inside. Tries wrapping the outside that did not work either. I found that the "bread box" filter works the best. I have some design ideas for one but have nit had time to draw it up in CAD yet.
