Changing the Fuel filter on a 07 S2R 800, I assume this will be similar on the S2R 1000, maybe somebody wiser than myself could post a reply and advise how many different models this would suit, anyway on with the show.
You will need:Flat blade Screw driver (long and thin would be a good Idea)
Socket set and Allen drivers (Allen keys will work, but the Socket set and allen drivers make it easier)
Wire cutters (for any Zip ties that are in the way)
Zip ties (To replace any cut zip ties)
Needle nose pliers
Nice long Extension for your socket set (Not essential, but makes life easier)
Fuel Filter (Thanks Desmo times)
Hose clamps (I used 1 x 40mm to 65mm and 2 x 6mm to 16mm from Tridon)
Lots of old cloths/rags and 2 x Soft towels (Don't raid the linen cupboard, they may get fuel on them)
A full bucket of water (Just in case a rouge spark starts a fire)
OK, Go for a long ride and get that tank empty, I went for a long ride this morning, kept going until the fuel light came on and then I rode another 30km's after that, this ensured that there was almost no fuel in the tank.
DO NOT RUN YOUR TANK DRY!! YOU RISK DAMAGING/DESTROYING YOUR FUEL PUMP!!If you can't go for a ride, get a fuel safe container and siphon the fuel out of the tank..
Next, place your bike on stands (if you have them) this will make the bike easier and more stable to work on.
Now remove your seat and place that somewhere out of the way so it won't get damaged.
Ignore the wire cutters in the photo, I was removing some zip ties before gently lowering the Tank down onto the waiting towels
Nice solid front and rear stands from Anderson Stands Australia. makes life much easier when servicing or...... Replacing fuel filters
Gad damn my Garage is a mess, I really should clean it up!
Anyway, back to the show!
Lower the tank back onto the towels, while tilting the tank back ensure your not stretching any fuel or vent pipes or power leads.
Unplug the power lead to the fuel pump (Centre right of Photo)
Remove the Inlet and outlet pipes, this is where the long this flat blade screw driver comes in handy, I used the tip of the flat blade in between the alloy pipe protruding from the alloy base and the little clips on each side of the pipe connection, gently prise them out and clear of the alloy base.
Be gentle, they are plastic and easy to bend out of shape or break.
Get those rags/cloths out, some fuel will spill from the lines and the housing/tank
It should now look like this,
Remove the Vent lines, this is a personal thing, I just found this made access easier to remove the plate from the tank, you will notice the nipples on the left of the tank in this photo. (below)
(Ignore the LEDS on the left and right of the photo, This bike has a LED kit, purely for wank value!)
Remove the six (6) Allen head bolts holding the plate in place (4mm allen head bolts) again have some cloths/rags nearby to catch any spilled fuel when you lift out the fuel pump assembly
(Might I add, if you haven't already, put your cigarette out, it could get kind of crispy if you don't)
This photo shows the fuel pump/filter assy sitting on my work bench, I have replaced the filter with a Napa filter, you will notice the plastic OEM filter sitting on the bench.
Some Points to note:* The OEM filter has a small plastic threaded tab in which a screw attaches it to the assembly, I cut this off and
reattached it to the housing, as this screw is a vital earth point for the pump and the low fuel light. (You can
see the tab just to the right of the Hose clamp, Yes, with a bloody big arrow pointing at it!!)
* The OEM fuel line clips are almost impossible to remove without destroying them, I used 2 Tridon hose clamps
to replace them at each end of the filter, I was assured at the parts store being stainless steel they should be
safe to use in the fuel tank (I found out later that Lt Snyder of Desmo times does the same thing apparently)
* Check the housing's large O ring to make sure it is not flattened or nicked/damaged, mine appeared OK and
upon reinstall I had no leaks.
* While the assembly is out check all the lines and connections for wear or cracking
The Napa filter has no mounting tab, so I used a hose clamp to attach it to the Assembly, here is a photo from the reverse side of the pump assembly.
While I had the tank open I removed the last of the fuel and wiped out any remaining grit or rubbish I could spot
I reinstalled the Fuel pump/filter assembly, Made sure to check and then double check all connections, I had one little leak from the outlet plastic plug after I plugged it into the base, I had not seated the little clips correctly, clipped them in all the way and no more leaks.
I then took the bike for a ride to fill up the tank (I only put 2 liters back in when I put it back down), I checked the bottom of the tank to ensure no leaks while out and about just to be safe.
Final note: The Fuel pump now has a lower pitch note and is quieter, after consulting with Lt Synder of Desmotimes, he said it is quite normal for the pump as it works harder (EG: Dirty filter) it's pitch will rise and it will get louder.
When I put clean fuel back through the original filter the fuel that came out the intake side was very dirty.
It has done 15000km's with our shitty fuel up here in northern Australia, so it has done well!
I hope this helps!
