The Harley maintenance table says replace at 100k. I'm sure they know more than I do about it, but today marks the second time I've replaced them. The first time was at 48179 miles, and today I have 82066 total miles on the bike.
This is what it looks like after only 33887 miles. The junk in the strainer is not magnetic, it's just crud. So, like @Steve Cole recommended in another thread, I'll start doing this every couple of years.
Anyway, I thought some of you might find this interesting.

Fuel filter at about 60K Miles. Maintenance Manual shows 100K. I'm going to replace it again at 100K.

My feel is that as the fuel has changed over the past several years, the new fuel cause things to breaks down more in the fuel tank area and it ends up in the fuel filter. If we could only go back to the days when the fuel did not have all the additive crap in it, we would be much better off. So for now it's every other year for me regardless of how many miles I put on it.
Tell.me your NOT putting that nasty filter BACK in till you hit 100k!!!
The very first thing I did when I bought my 2010 RK 3 yrs ago was change the filter.
it had about 32k on it.....and it looked like yours.
As has been mentioned, today's fuels have so many additives.
Plus......who REALLY knows the condition of the storage tanks at the gas stations?
Maybe it's just OCD, but for the money we spend on our rides the peace of mind that comes from regular filter changes is more then worth it.
I'm going with every 50k.......but that's just me.

I have been suspicious for a long time that the fuel filter material turns black when exposed to gasoline even if no fuel ever flows through it. New filters are always better than older ones, just saying that the color alone does not indicate a need for changing. To validate that theory, I would have to buy a new filter and put it in a jar with gasoline and change the gasoline every few weeks for about 2 years. I am not about to waste my time and money doing that. My 08 King was not on the recall list for the filter basket recall. Years later, the filter basket failed about 1000 miles after a filter change. The filter was a light gray rather than white even after a short time exposure and relatively low mileage.
In 08 the filter change recommendation was 25,000 miles. A few years later, I believe it went to 50k. Will have to recheck my book on my '23 to see if it is 100k. I believe I won't exceed 50k regardless of what the book says. Every 2 years "just because" seems a little excessive to be disturbing the fuel lines and fuel gauge mechanism so frequently, especially if you have only run, say, 10k. As always, whatever makes you comfortable is what you should do.
