Changing the Fuel Filter on a S2R800

AFAIK, it's just a convenient screw to attach ground leads from the pump and fuel level sensor.

I will go out on a limb and guess that it not a convenience thing as it  forces the factory to use a more expensive filter and a more cluttered pump wiring harness.
I bet there is another reason, It would be too easy to just ground the pump as they used to, externally.

I'll guess plastic and static electricity warrants the ground on the filter.

How often do these buggers need to be replaced anyways?

[clubhousemotorsports]

I recommend changing them every tune, A few thousand miles here or there will not make a difference. I have been the victim of a clogged filter and i feel it should be a part of a regular maintenance.

early supersports had plastic filters for about 10 years with no ground straps.

but then back in the day they used to have bare wires in the fuel tank also.......

What clogged it??  Just dirt or what?

i filled the 851 with fuel one day and got about 3km down the road and it stopped.  blew the hose from the pump off at the filter end.  took it apart and the filter was so blocked i couldn't blow thru it.  cut it up and sat the paper into a cone shape and poured fuel on to it - none came thru.  dunno what it was.  went back to teh servo (around the corner from home) and got the usual "the manager's away" story.

we used to change them at the first service and every 10,000km.  now we do them every 20.  we use the same steel filters in bmw and they specify 40,000km - we do them at 20 too.  mv is 12 or 24 depending on which schedule you read.  the aprilias use the same filter in some models (and the later plastic one too) and they don't specifiy an interval for lots of them.  i think the idea is that plastic tanks don't need filter changes.

i've seen a bad tank of fuel block them enough to clearly effect running, anywhere from 2,000 to 15,000km.  and i've seen them go bad 500km after a tank repaint or repair.  kind of luck of the draw really.  replacement interval is often just a back up.

the older carby ss ran a plastic one in the tank without earth, but i'm guessing those pumps generated a lot less heat with effectively zero pressure, if that's a consideration.  dunno really, but i wouldn't run without the earth simply for liability sake.

might be a dopey question,  but wont all the fuel spill out by dropping that bottom plate?
Do you have to syphon all the fuel out of the tank first?

[clubhousemotorsports]

if you have a fuel tank that the pump comes out the bottom you are best to remove the tank and flip it upside down to change the filter. drained is best.

My reasoning for doing the filter at every major service is simple. The filters do not cost much $$$. the hassle if yours clogs could be great.

I also had filter issues on my 851 and changing the filter at road side was not fun. newer bikes with the pump  attached to the base are going to be much worse.
My case was a tank full of bad gas, If the filter was fresher it may have had enough flow to get me home. hard to say. I have always kept the filter fresh since and no problems so far.
