Commando Oil Filter

Hi All,
Is the Fram Filter PH2389 a fit for the Commando?

Some guy on eBay is offering them & all I have ever used is a Champion model.
Thanks,
Stephen

Does anyone know of a Wix alternative that fits the Norton?

You can plug in the framm number on the wix site and they will give you the WIX number. They do have one.

Wix 57013 identical to the NAPA PS7013
Also look to the K&N kn153. Order it right of their website.

Baldwin B474. Longer than most. More filter media, more oil.

A friend noticed the filter on my 850 and tried to convince me that the oil only gets filtered at low presure and tried to convince me that at normal running presure the filters by pass valve opens and the oil is no longer being filltered. Is there any truth to this? I find it had to believe.

For there to be pressure in the return line there has to be a restriction to create back-pressure, it ends in an open hole so no pressure. There are bypass valves in some filters but these work when the filter clogs and creates the back pressure, but it has to clog first.

It's the pressure differential caused by a blockage within the filter which causes the filter's bypass (if fitted) to open, and that is extremely unlikely to happen if the filter is changed at the normal service intervals.

NAPA number here is PS7013. PH 2839 is an old Fram number and although I cannot find it, the Fram number I have found is PH6019. The K&N kn153 is top notch.

FWIW
I think it is important to know that this link http://atlanticgreen.com/oilfilter.htm is over 20 years old.

20 year old info for a 37 year old bike just about balances out, right? Has anyone used a K&N ? I wonder if they are really a much better fillter for our systems? I have no trouble spending a few more smackers for something like a fillter that could add many miles to the bikes life if it works and I do use there air fillters in all my cars & but being washable they pay for themselves.

I put 13,000 miles on my 69 Commando with no filter and no problems and the sludge trap was 90% clean when I broke it down. It may depend more on how much the oil is changed or how it's used? I did install a filter recently, by the way.

I use it. Any filter that fits a 2000 Ducati 900 or 750 ss and many many more models and years, will fit and supersede any filter for a Norton. Like DogT said, oil filters on a Norton is an after thought (for the most part) although a good after thought.

This is a free flow, low bypass, anti drain back filter that has a larger capacity than most. Welded 17mm nut makes the day. It's easy to get, $13.99 with free shipping when purchased right from K&N.

I use the K&N 153s. Although in Boston, I buy them from Sir Chris Kelley in California, ca-cycleworks.com, for $12.
