Heard a lot about the 5 way joiner under the seat getting blocked, and has to be cleaned out with a pipe cleaner etc, what is the outcome when it is blocked???

Essentially it starves for fuel....idles but wont rev, F1 light may be on or flickering.

The 5-way connector is under the fuel tank, sitting under the mass of tubes and cables in between the throttle bodies on the 1300.

Thanks Chaps,
I know the old story, no light flickering but has anyone really had the bike starving for fuel??? I have a small problem when the bike gets really hot (120kph with a pillion on a hot day) starts a jerking motion when feathering the throttle or on a slight accelleration..??

Sounds like a possible symptom of mild starvation. They're thirsty at 120 with a pillion, so that's when you'd notice it at first.

Once it starts I have to stop and let the bike cool down for about 30 minutes to stop it ???

The 5 way connected the inlet of each throttle body and to the Manifold Absolte Pressure (MAP) sensor.
This sensor is one of the inputs to the Electronic Fuel Injection (EFI) computer.
If the connector is blocked, a vital piece of the information to the computer is missing and the engine can run rough, lean or rich depending on engine temperature and ambient temperature.
