To expand on cbxer's comment, the 109 actually has two filters. If you look at the parts diagram there is a filter inside the pump that is listed as "Fuel Filter (for high pressure)" and then the one we change, that is listed a "Fuel Mesh Filter (for low pressure)". I've never heard of anyone changing or cleaning the filter inside the pump, or even if it can be. Kind of sounds like the same design as you mentioned on your Honda. There are instructions in the service manual on how to disassemble the fuel pump, but no mention of the internal filter in that process.
My B-King, the pump has to be disassembled to get access to the filter. I did it without a manual or a diagram, it was that simple. But who knows on any other bikes And the B-King responded to a plugged filter the same as the Nine. Backfired, stumbled on throttle application, and stalled when coming down to a stop. A new filter fixes it right up. It's even smaller than the filter the Nine has. And hangs totally below the bottom of the fuel tank, in a can on the bottom of the pump. It's the lowest point in the entire fuel system.

When I took it into Suzuki in 2021 to diagnose what was wrong with it, a different problem that occurred a few months after I changed the filter. I told the mechanic I had already changed the fuel filter. He said "really, how did you do that?" LOL!!

The B-King is a PITA to do anything that is under the tank. Takes nearly an hour to get everything off the bike so you can take the tank off. Even worse getting it put back together properly.

Mine was dying when coming to a stop occasionally.. Once I replaced the filter with one of the Ebay ones, the issue was gone, so they worked for me. 2 for $10 or so is much better than 1 for $50+, even if you have to change it more often like bigpapa said

Anyone can tell me when we need to change fuel filters, mean after how many miles??
There is no schedule. If you experience loss of power under hard acceleration then it might be your fuel filter.
If you have no problems, relax, and enjoy the ride!

Mine has been fairly consistent with about every four years or around 10,000 miles. Even my B-King needed a filter change at just around 10,500. Having said that, I'm now at five years on the M109R, and I'm hoping my filtering the fuel going in will keep it going for a lot longer than this.

There definitely is no schedule, or not that I've seen. I've changed mine about every 10,000 miles just for preventive maintenance, and it's never had any symptoms of being clogged. No stumbling under acceleration or dieing at idle.

Mine has always let me know when it's bad. The only exception being the one time that the little sliver in the fuel cap got out-of-place. It was stumbling then as well. But, removing the fuel cap and putting it back on cleared it up, briefly. So that told me there was something wrong with the fuel tank vent, which is that little sliver of metal in the cap. Have no earthly idea how it got out-of-place, but it was.

I changed the fuel filter on my 2013 m109r a couple of months ago for the first time . The bike has 8,000 miles ... Bought it at the dealer , it cost me $82.00 plus tax .
I had no problems filtering , just thought it was time to replace it to avoid possible future problems . It was black but it was filtering ok thou .
