Hi all, I’ve recently picked up a second K25. I have a 2007 in France, which has previously had its fuel strip replaced. The one I have bought in the UK (2005) has dodgy fuel level readings (of which I was aware when I bought it); it reads Full for around 120 miles, then jumps to around 1/3 full and continues to read lower as the remaining fuel is used. I figured that the fuel strip was dodgy, so ordered the revised version from Motorworks. I’ve just pulled it apart to fit said revised fuel strip, but found that it has a float sender. On this sender, the float hits its top stop at around half a tank, and stays there submerged with higher fuel levels. Overall, I can work with this, as it reads sensibly at lower fuel levels, but I was wondering if this is normal?

It could be that yours was converted to float from a strip. Is the float mounted on the pump or the filler? I've seen a write-up where someone had to bend the float up for it to read properly, I think this was for the case when the float was mounted on the pump.
 
the float on the pump on small tank bikes (especially if used in conjunction with the proebeemer adapter gadget to fake strip signals for bike with the wrong ZFE control unit) works just as you describe

the strip is MUCH better - but you need to see if you have this black box 60mm x 45mm x 15mm in line gadget on the wiring beside the pump or of the wiring has been re-pinned.... no gadget will mean you need to swap the wires back - easy but the tank has to come off
