Just received a text from the vendor, he's cancelled my viewing, said that he took the bike out and has broken down. He is waiting for recovery. He thinks it's the fuel pump.
I said it's probably the fuel filter falling apart. suggested he looked in the tank with the ignition on and see if he can see fuel swirling around. Or the fuel pipe has come off. He said it is swirling around. He also said that it had a recall to replace one of the hoses.
Stroke of luck for me, I can imagine it's the original part plastic filter, after read about these issues on here.
