fuel pump 6 Years, 6 Months ago  
When I turn the key on I don't hear the fuel pump going on. Never did that. In the mornings it's hard to start but once it's started there's no problem.If I stop it starts right away but still no pump sound.Anyway to test the pump? Ken

best way to test the pump is to pull the line going into the carb and turn the key. the pump wont kick on if there is enough pressure.

Maybe I'm not getting the joke, but wouldn't that just spray fuel outta that line?!?

Yes IF the pump is working it will give you a continuous stream. Put the hose into a gas can to save the gas.. If it isn't working then it won't spray. Good test to see if the pump works.

Yea, I wasn't trying to be an ass . If the fuel pumps out your pump is fine if it dont then the pump is shot or not getting power

If the Bike runs its working.

The only time I hear the start up clicks of the fuel pump is after the bike has sat 12-18 hours, the pump repressurizes the system. The fact you do not hear clicks most of the time is good, it means your needle valve and seat inside the carb are sealing properly. My bike used to give a couple of clicks every time I turned the key and eventually got to the point it was idling poorly, I had to replace the Needle Valve and seat, they were leaking and this can be attributed to ethanol in the Gasoline in my less than humble opinion.

Go ride it.

Good to know. Mine does that exact thing (rarely clicks unless it's been sitting overnight). Makes perfect sense and gives me a little more piece of mind.

(and some argue I have very little mind to give up)

wouldn't it be easier to just start the bike and turn off the petcock so the carb runs out of gas and dies?
Turn ignition off, turn the petcock back to the on position and then turn on the ignition switch. THe pump will turn on and you'll be able to hear if it is working and pressurize the carb.

Make sure your kill switch is not on...becuase if it is and you turn your key the pump won't work. just saying..
