Oil filter nipple exchange?

[ldbandit76]

As you may or may not be aware, the options for high-quality oil filters for the Bandit are rather slim, as per this web page:

http://motorcycleinfo.calsci.com/FilterStudy.html

Mark, the author, asked me about possibly exchanging the nipple in the engine block with a compatible part from Suzuki's line of outboard engines, thus allowing the use of Pure One filters.  Has anyone heard of doing this?  

Here is Mark's message to me...

Btw, you seem to be hooked up with a bunch of other Suzuki riders. I
have a homework that I've been unable to get done. The oil filter on
Suzukis fits in a nipple sticking out of the engine block. The nipple
screws into the block. It has 20x1mm threads on the filter side, and
something else, I think pipe threads on the engine block side. There is a
comparible nipple for the Suzuki 4-stroke outboard motors which has the
same threads on the block side and 20x1.5mm threads on the oil filter
side. If someone could look over an outboard motor parts fiche, order
the correct part, and verify that it can be used in the motorcycle
engine, then we could all use Pure One filters and feel a whole lot
better about our oil. I don't have a part number, there are no Suzuki
outboard dealers anywhere close to where I live.

Has anyone even removed or replaced their oil filter nipple?  Even with a stock part?  

This may be a lot of work for a small benefit, but it's an interesting question.

I did not know that  the filters we have to choose from are rated that poorly.  I  hope some of the other filters he is going to test will be better!  I measured the distance from the bottom end of my stock suzuki filter to  the exhaust header and it looks to me like the "pure one" or "super tech"  filter would be to long and  touch the pipes. the bosch might work,  if it is not any  bigger around.  I hope  some one comes up with a better solution.  I guess I will keep shelling out the big bucks for the over priced suzuki filter and  keep changing it ever 3000 miles to avoid an old sticking valve in the filter.

I had a 1986 1052 block, so I pulled the nipple to measure. It is 32mm long, 20x1 on the filterside, and 19x1.5, on the block side. The 19mm thread is a stright thread, not a pipe thread. It should be a easy job to machine a nipple to fit a Pure One filter. I might give that a go myself.
Thanks for the idea.

Even the OEM filter may not be that good.  They're being made in China now, not Japan.  I have a Chinese filter I'm going to send to Mark for evaluation.  If that one isn't too good, either, we may be forced to do something drastic.  

BHolland - if you can machine a nipple that does the job, would you be willing to machine two (or a dozen) and sell the extras?  I bet you'd have at least two buyers.

I will pick up a Pure One Filter and check out the thread size, and then get a price from a friend, who works in a machine shop. I will post my results.

I got this info from the internet

If you have the room, I recommend the longer filters.

I am afraid the 3.25 inch long filters  would touch the exhaust at the very bottom edge of the filter. I think the 2.5 inch filters would work fine. I am very interested in a nipple if some one can get it figured out. I think that just about every one on the board  would be interested in a better filter if its a pretty easy conversion.

[ldbandit76]

I'm also looking into machining a nipple.  BHolland, please don't stop your investigation, since my machinist is, umm, not very reliable.  We'll see what he brings back, and when.

This topic isn’t nearly as kinky as the subject would lead you to believe.

As for "good filters", i got 30k out of my Amsoil sf103
last oil change. Good numbers from the oil labs.

Now I would be interested in seeing if I can install a sandwich
switch so I can remote up to a filter(or two) in the fairing.
This would allow the use any car sized filter including
the new nano-fiber oil filters amsoil got from EAo.

A couple of these 'vette sized filters(I'm getting one for my car)
should filter nicely as well as providing some extra cooling.
Can you say seven quarts of PAO oil?

     

[bandibull]

That is of course the SMF109 Amsoil oil filter that I've been using
on my Bandit.  The SMF103 is used on the FZ1 among other
things and as I was recently turning a fzzy onto the Big-A recently
I no doubt had that number stuck in my brain.

Besides I bought my filters several years and 70k ago.
The memory isn't what it used to be.

P.S. Also on the topic of remote filters.  Am I correct in thinking that
as long as I pick up a universal filter reclocation kit thats M20xP1.5,
it will fit?  Or am I missing another variable here?

The STP filters are quite good.  I have been using them on my bikes for ten years and have never had an issue.  Alot of miles too.  But consider this.  Modern oil is so well refined and filtered that unless you have an opening in your system there is vitually nothing to filter out.  Enjoy!

The filter isn't there to filter new oil; it's there to filter used oil.  And used oil obviously has a lot of crap floating around in it.  Why do you think it turns black?  Cut open a used oil filter the next time you change yours, and take a look at the media.  I'll wager there's plenty of garbage caught in it, unless you have very short oil change intervals.  

I'm sure there are adequate filters available.  I'm just looking for something that's better than adequate, mostly because I can, not because it's absolutely necessary.  

Any luck with your machinist, BHolland?

If advertising is to be believed Perf-Form filters are very good, made in the U.S. and reasonably priced.  Check their web site at <www.perf-form.com> for a listing of your bikes and check out their claims.

I've been using them for many years and order half a dozen at a time to keep shipping costs/unit down a bit.  

My Nighthawk, W650 and Bandit seem to get along fine with them even at extended mileage changes (6-10K).  Oil analysis by Brookstone Laboratories says the filters are working well with minimal particles found in the analysis.

Is that Blackstone Labs doing your analysis?  I've had them check the oil from my cars, but not the bike yet.  

You should do all of us a favor and ship one of your filters to Mark here:

He hasn't reviewed the perf-form one yet.  I just sent him the new Suzuki OEM filter (from China) for his page.
