What's the part# for the hose?
NAPA H 209. It's a 1 foot piece and sells for about $30.

I just noticed you have an S2R. The OEM filter has a ground lug and the NAPA doesn't. Also the NAPA hose is straight and it looks like the OEM is pre formed. You might want to consider OEM parts for this application. I've never used the NAPA stuff in this application.

I ordered a new OEM fuel filter. Why is it recommended to replace the hose?

I mentioned that the bike runs rich. If the fuel filter is not flowing properly, wouldn't it run lean instead?

It might be mapped rich and starving for fuel at full throttle due to flow...or rather lack of it. The fact that it will rev at less than full throttle kind of suggests a flow problem.

It also eliminates a possibility without replacing a non maintenance item.

Your S2R has the corrugated plastic hoses, I've not seen those degrade.

The earlier models had rubber hoses, and if the bike sits for a while, the current ethanol-contaminated fuel will attack the rubber hose.
I've seen them spring a small leak that reduces delivery pressure enough that the bike then runs poorly.

I know the vet has seen bikes with clogged/restricted filters show full throttle issues.

If you are in there to change the filter on an older bike with rubber hoses do consider replacing them with with SAE 30R10 hoses.

Okay so I replaced the fuel filter with an OEM one and now it won't start. I can hear the pump prime but it just won't start. It just keeps cranking and cranking. Some some occasions it seems to fire up for 1 revolution but just goes back to cranking.

I was quite sure that the filter was put in the correct position. But even if it's the wrong direction it should still start right?

When I had the assembly out I noticed a little wire that was attached to the hose clamp. It looks like someone else replaced the pump at one point. What is that little wire for? I ended up safety wiring it snugly to the assembly and the little tab on the fuel filter where it looked like it belonged.

When I pull the plugs I notice the the horizontal cylinder plugs were little damp but the vertical cylinder plugs were bone dry. Is it normal for 1 to be wet and the other dry?

What else should I try?

did you reconnect the hoses under the tank in the correct order?  they're just vents but . . .

I never removed the vent/overflow hose. I only removed the in and out hose with the plastic clips. Those hoses are different legnths so you can mix them up and hook it up the wrong way.

Opened it back up. Fuel filter pointing the right way which toward the bottom left in the photo.


Unplugged the fuel pump. Pulled 2 of the spark plugs out, grounded it and cranked it over. I have spark.

Plugged the fuel pump back in. With the spark plug removed, I cranked it. No fuel spat out of the spark plug hole.  Am I not getting enough fuel??

Reconnect the little wire with the thingy to its original position and try again . . . it should start with no issues

I believe that is the original position. It's held securely with safety wires. If you zoom into my photo you can make it out.

What is the wire for?

The wire is a ground to dissipate any static electricity that might build up from fuel rushing through the plastic filter.

Previous models didn't use it for whatever reason, but they used a steel filter.

I doubt the wire has anything to do with your issue.

I'd cycle the key multiple times to purge any air
