Subject: Fuel pump defect?


Hi,

since a few weeks I sometimes have the problem, that my @ suddenly stops
running, as if it were out of fuel. It stops first operating one cylinder
and then stops the second one, too. Turning the fuel switch to reserve does
not help. Usually I managed to restart the engine after a few minutes of
waiting without problems and could proceed in riding.

As I presumed a fuel pump problem, I filled the tank on the very next
occasion and can put about 16 liters in then. The engine continues riding
then.

But: Last weekend I rode 2900 km and had no problems at all. One time I
went 350 kms with one tank filling without a problem.

Now to my questions:

  - If the fuel pump is defect, is it true, that the bike runs without 
    until 2/3 of the fuel in the tank is gone?

  - How can I test if the fuel pump is running?

  - Is there the possibility, that the fuel pump is only sometimes defect 
    and operates on other times?

Has anyone experiences?

take care - Marcello.
