 Posted: Sun Mar 06, 2011 11:55 pm Post subject: I have a question about air filters for 1973 CL 350 |
 |
|
Does anyone have an opinion on putting newer air filters on a 1973 CL350? I was looking at the UNI Air Filters for my bike and I am curious whether they work well or not.
Thank you guys for your constant help.

Two problems. First, the fuel system is calibrated to work with the restriction and flow characteristics of the stock air filters. Using any non-stock filters, you could end up chasing jetting and needle position till you're blue in the face. And you won't get any performance increase. Second, the rod that passes through the filters to secure the side covers needs the OEM filters and metal covers for support. Without that, the side covers will move around and probably get damaged, especially the one on the left side.

For me, faced with no-longer-available pleated filter assemblies for my '74 CB200, the best bet was to burn out the old pleated paper, cut a piece of generic 1/2 inch thick air filter foam to fit around the remaining screen, glue it into place using Gorilla Glue which sealed up all the foam to the OEM metal housings, oil up the filter element and squeeze out the excess and put 'er all back together.
The bike ran (runs) perfectly after this, and required no re-jetting or anything. Best of all, you retain all the original boots, metal brackets, fittings, etc. With the metal covers back on, you can't tell they're not OEM, and they do the job - no dirty air!
Here's a link over to the HondaTwins site where I posted about it:

Yep. That's the best alternative when you can't get the OEM filters. I also use that foam to replace the filter elements in the crankcase ventilators of the later models.

Or, get a K&N air filter and never have to buy another air filter. Have done it on all my bikes with great success. No rejetting or carb issues.

Does the K&N filter not suffer from the same problems of other filters? Namely that it allows more air to pass more easily (or less air less easily) than does the stock filter? Do they specifically mimic the stock filter?

| Is there no way known to man to simply clean the paper in the stock filters or even to burn out the paper and rather than replace it with foam, just replace it with more paper (whatever kind of paper that is)?

I put UNI filters on my '73 CL350 and bumped the main jets up to #120. No problems. Of course, I'm now running without side panels (but I'm in the process of making some custom fiberglass side panels of my own that have cutaways for the filters).

If you use the stock airbox setup, you don't need to rejet. My original post was intended to reference the stock replacement with K&N, rather than individual pods (those will require rejetting).

| K&N does not make a stock replacement filter for the 350 twin, they only offer pods.
