Hi all,
I#ve done a search but seems nothing i can find that answers this, so maybe someone can help.
The other morning i started my 06 Bob fine, starting perfectly as usual, but shut it off after a few seconds as the shed door had blown back in. When i went to restart she didnt start as quickly as usual, so i let off the button. (i dont think there was a problem, just that i was maybe being over careful with the starter).
however, as soon as i let off the starter button, the injectors kicked into action again, pumping in more fuel. i tried again, and this time she was maybe slightly flooded, so no start, so again once i let off, she pumped in more fuel, making the situation worse. now there was a nice smell of fuel when trying to start, and further attempts just made it worse. so i just let it for 10 -15 minutes or so, and she just about started.

Should the efi be pumping automatically just after a failed start attempt?....and is there any way to avoid this?.....wouldbe nice of there was a hidden way to disable this, or what is the best way to clear a efi that has flooded?
thanks for any help.

 

pull the fuse for the EFI and turn it over a few times to burn out the extra gas.

ah. good idea.
thanks Woody.
it was pissing me off that i had no control and couldnt kick it to clear it.....

 

I might be wrong but I think you are hearing the fuel pump run each time you hit the start button. The engine must crank several revolutions with the electronic fuel and ignition before it fires, It is looking for timing, temp and rotation speed. If you do short crank cycles and let off the key before it finds all this information the next time it takes even longer to start and finish the process again.

 

Hi Kruzin,
thanks for the info. but yes for sure the pump runs each time before hitting the start button. I had been giving it enough turns to start...never timed it but 3-5 seconds maybe. (usually starts in maybe 2, or even 1 second).
But what happened was for 1 attempt it did not start. When i released the starter button the fuel pump goes again if it sees a failed start.
So i ended up with a flooded bike pretty quickly. i probably then shut everything down to give it a chance, so therby injecting more fuel again before & after the next attempt, making it worse and worse..!!...

 

i have a bob and was told when i bought it that it wont like being started, stopped and started again quickly. i did the same as you the other day and i had the same problems you had. must be a peculiarity of this engine with fi

 

I only allow the pump to run during cold starts (shut off for an hour or more). Once the bike has been warmed, I hit the start button before the fuel pump primes again. The only time I have experienced a flooding issue is if I race the bike and shut it down, then do a restart.

 

ah. cool to hear its not just me then.
& thanks also Geoseismic, i hadnt thought about getting to the button before the pump.

 

The system has an anti flood mode built in which can also be used for checking leaky injectors. When you crank it at WOT, the injectors are actually turned off. This prevents you from having to remove covers and pull fuses.
