with regard to the scotts filter, i believe its a re-branded J&P...

as far a micron vs. micron, a synthetic oil molecule is 12 microns in size...(averaged) as lee posted earlier. if this is the case, and a stock harley filter claims 5 microns full pass, that would mean that the oil molecules are not able to pass through the filter media.....

i would guess that the harley filter falls in line with the rest of the tested paper filters of similar quality on the market place, with respect to the level of filtration they are capable of.

and sisnce harley doesnt build their own filters, this is almost surely the case...

if in fact the harley filter does filter to this level, the filter by-pass system would surely activate, allowing unfiltered oil to circulate through the motor....so the question remains....is it really 5 microns, or is it closer to the 25-35 range as seen in other filters...

either way, the inside of my motor is clean as a whistle. can i say the filter is the reason for this ? or the more than frequent oil changes the motor sees....i'm leaning toward the oil changes as the primary cause.......

and i dont miss the degraded filter paper getting into the motor either.....g

This is an old science experiment that is still used today with a great deal of accuracy. It is based on the fact that when floated on water, oil will form a film that is one molecule of oil thick. Pretty cool.

Measuring the Thickness of a Molecule .........

If you take the results and convert it to microns, then a molecule of oil is0.00833 microns, not 12 microns. Granted, some oils probably contain a few more atoms than other, but there is a big difference between 0.00833 microns and 12 microns.

If a Harley 5 micron filter didin't let anything bigger than 5 microns pass through and if oil is 12 microns, oil could not pass through the filter.

I could not find any reference to oil being 12 microns. Did I miss something?

Here is the link to the info page at Pure Power....Their filter is set at 22 microns absolute...Also reference is made to "Beta" filter testing at 5-10 microns...More info is coming from Pure Power..The owner/developer is an aircraft engineer with a background in oil developement.

Good information for sure.

I noticed that Pure Power has listed on their site that they are the ONLY reusable filter certified for FAA applications.

When I started working with K&P Engineering a couple of months back, he had mentioned that they to, had recently received their FAA certification on their filters which they explained to me was an extremely stringent process.

At the time, it didn't register with me the value of that information. But if you think about it, if Pure Power and K&P filters are good enough for a 250k Cesna all the way up to a multi-million dollar Boeing, than it can't be all that bad for my $15k bike.

Just my 2 cents on the topic.

Very true..I talked to the owner/founder of Pure Power on the phone about 2 months ago..what a wealth of information he gave me...Wow ...He overloaded my brain...I have been running the PurePower filter on my own scoot...combined with Mobil 1 oil I have seen over a 25 degree decrease in oil temperature alone...I know several people that have been running them for quite some time and swear by them....

as do i...the short of it is "i suppose" these filters are true to their claims, and are a benefit to the motor.....they dont scare me....i use them, and they work better than a paper filter in several different ways.
if there good enough for a million dollar aircraft, there good enough for a 10k sporty.....g

Harley's filters are made by Champion Labs. The same people that also make WalMarts filters, Motorcraft, AC Delco, and a host of others.

Oil Filters Revealed - MiniMopar Resources

I've personally had email conversations with them.

Champion Labs - Electronic Catalog


Another member at another forum also wrote to them, receiving the same response and a few others.

Despite the "Micron rating" the Beta ratio and Max flow rate was not discussed, and I was told that not knowing those two factors, and just having the micron rating means nothing. It's only part of the equasion.....

I believe HD uses the Beta rating...rates at a lot lower number...

That's my point..... I have NO CLUE as to what these ratings are or mean, yet people are talking about a "micron rating" (the only one I know what it is) and hanging their hat on it, yet the two other important factors that may explain all of this, aren't even factored.
