I was wondering if the 76 air cleaner could be put on a 75 kz400. The filter for the 74-75 is really bikes is really hard to come by and expensive.

Here's the low-down: The 76 frame is exactly the same as the 74/75 EXCEPT FOR a few differences in the tabs for mounting things like side covers and the parts around the airbox.

All of the parts *around* the airbox are different on a 76 from a 74/75.

So, while an irbox from a 76 *would* fit in a '75, you need all the mounts welded on your frame and all the other mounts and parts from *around* the airbox to make it work.

I feel you pain buddy, I'm glad I have a 76 for my rebuild project. Here's a pic of my airbox experiment on my 75:

There is a couple of dealers that are selling the 74-75 filters for $12~14 on Ebay. That is less than you have to pay for a KN pod filter.

Also the battery box and the tool box are different on the 76 model btw. And some of the elctrical components are located on the opposite side of the bike.

Hmm. Good deals, but I was looking for a way to use a K&N filter. They don't seem to make it for a 75. If they did, I'd go that way since I wouldn't have to change it ever. How hard are the K&N pod style filters to install? That sounds like the ticket.

This is only my opinion:

Keep the stock airbox. There is plenty of info here and on Ibsen's site (kz400.com) on how to keep and maintain your stock airbox, including how to make a new one out of your existing filter chassis and an auto filter.

Pods are easy to install, and *can* be difficult to tune and maintain. Many people are not happy with the results, though others are. It's almost like religion...

bombloader,

I ran with pods on 75 for a few years, it was a pain.

I had to reduce the intake area with little metal strips to get it to start reliably, it ran too rich, and I got about 45 mpg (I think I should get 50+).

I was stoked to find cheap stock filters (they were $85 three years ago), and after rebuilding the carbs, setting the floats I can usually start it on the first press of the starter button. I have yet to check mileage, since i've only rode about 150 miles this year.

Thanks,

George
