>Hello everybody,
>
>You probably read the problem Marc had with his bike at the gas station.
>You have to deal with this problem in the folowing cases:
>- when you had no fuel in the tank anymore.
>- when the bike hasn't been driven for a long time.
>- in the summer after you have driven a while and want to stop at a cafe
>(or something else) and you
>park the bike in the sun.
>- the day after you drove verry fast and the engine became real hot.
>The reason of this problem is the folowing:
>The engine has to run in order to let the fuel-pump work.
>
>It realy annoyed me.
>But there is a solution and this solution is even cheap.
>The only thing you have to do is this: let the pump turn before starting
>the bike.
>
>This can be done in different ways.
>But I choose the folowing:
>I placed an adjustable timer-based relay (don't know the english name).
>This relay is activated when I turn the key to ignition.
>Then the relay gives power to the fuel-pump.
>The fuel-pump starts pumping. ( He can't pump to much fuel in the=
carburator. )
>After an adjustable time the relay switches off and the fuel-pump stops or
>the pump has stopped
>because there was enough fuel in the carburators.
>If there was not enough fuel in the carburators, simply turn the key off
>and back to ignition and it
>starts over again.
>There should also a 'diode' ( don't know the name for this electronical
>piece that lets the power
>through only in one direction. ) be placed so when you start the engine,
>there will not go any power
>from the orriginal wires to the relay.
>It is hard to write the technical details, but everybody who know
>something from electronics can
>make it or tell you what to do.
>There will be a scheme and detailed information on one of my pages in the
>near future.
>
>In my case I regulated the time to 3 seconds.
>After this modification my bike starts always with only 1 short push on
>the starter-button.
>
>There was only one question left: WHY ISN'T IT STANDARD ?? as in many
>fuel-injected cars and bikes.
