Hi All, Think I already know the answer but just confirming it here on my 1984 SR400 Was riding along and noticed as I was riding faster the bike seemed to struggle for fuel. Then all of a sudden a few back fires and the engine died. Pulled over and checked fuel. No fuel in the clear inline fuel filter between the tank and carby. one of those small triangle ones with a piece of fuel line between the tank and the carby. Disconnected the fuel line from the tank and carby, turned the fuel tap on and fuel came out. So not blocked. Put on a spare bit of fuel line directly between the tank and the carby, the bike started up second kick and ran fine afterwards. I am just putting it down to the blocked fuel filter which restricted fuel to the carby and eventually stopped flowing all together. Anyone else had this happen?

Have you done a filter autopsy to see what's actually blocking the mesh? I haven't managed to use one of those plastic inline filters long enough for it to block. They melt first from all the lovely ethanol they put in UK fuel. If you drained the float bowl, be interesting to see how many 'bits' made it into your carb. Should be close to none with the filter in place, but if it were me I'd still be curious....

Looks like parts of the fuel tank liner, specs of metal paint. Suspect it is from where the fuel tap was inserted into the tank and some of the paint got loose. Doesn't look like any got past the filter as it was all blocked. Aussie fuel is not the greatest either. So many different qualities out there. Float bowl all clear too. I was curious as well.
