Water in petrol

[Tone]

Hi all, on my 2020 strom 650, in traffic and rolling the throttle slowly I get a hesitation, and moving the throttle a tad more nothing seems to happen, then without moving the throttle all of a sudden it will accelerate? Could I have water in the system? any ideas would be helpful.. thanks Tony.

You could have, but why would you have?
Has it been laid up for winter at all, if so what fuel is in it etc.
I'm thinking the fuel may have gone off if it's been in there a while.
If not I'll shut up.
On the subject of water in the fuel though, if you filled with e10 a while back, that stuff is like a sponge.

Possibly...

In some petrol garages , if their tanks are near empty, it's possible some dregs of water can find its way into your petrol tank and over time it builds up in the bottom of your tank until it eventually gets pulled through the fueling system.

I get this occasionally (but it's happening more often lately) when I fill my Honda up,  it coughs and splutters for a few miles until all the water gets pulled through the carbs.

Try some fuel additive that disperses water , there's plenty out there.

Does your throttle move freely, and is it adjusted properly with the correct amount of free play?

One method of clarifying for certain whether there is any fuel contamination, is to do a fuel flow test.  https://www.v-strom.co.uk/smf/index.php?topic=18930.0
Remember that the container used to collect the pumped fuel, must be transparent to allow you to see through the side of the container. If any contamination it will be visible once the pumped fuel has stood for a bit to allow for possible water vs fuel seperation.

Isn't there a thing with ethanol and water separating, admittedly when stood? Wonder if the petrol stations are having issues? Triumph memories of expanding fuel tanks coming back to haunt me

IIRC, a good drop of meths in the tank helped absorb the water...

I thought water attracted Ethanol?, it's a popular method of removing Ethanol from petrol by vigorously mixing water with the fuel then leaving it to stand, the Ethanol/water settles to the bottom and you draw the "good stuff" off the top.

Either way I guess the ethanol and water ended up at the bottom of my mis-shapen triumph didn't want to know plastic tank and the meths helped bring it all together...
