low fuel = stalling?

i know its been discussed before but i recently took about a year hiatus rom the 9'er and i noticed thatevery time i turn it to the "on" position or flip on the kill switch it sounds like theres air in the fuel line for a split second? anyone else notice this? that doesnt necesarily mean it wasnt there before just that i dont remember it.. i dont know if its related but the other day my light came on and i was able to fill up right away and it only took 3.7 gallons.. but typically by my math it usually comes on around 1.1 gallons left, the problem is when it does finally come on even the slightest braking will kill it. and if i ride a few miles with the light on even decell will kill it. in traffic this is fairly dangerous and scary... so any one? do i have a problem?

for some reason it sounds like it is not actually going into reserve... that tank completely dry holds 5 gallons... therefore you are correct about the amount you have left.... i would pull the tank and check the fuel pickup make sure there is no trash in it.. check fuel filters check vents make sure the tank isnt pulling a vacumn.. then if it still does it i would pay someone smarter than me to fix it....lol... keep us posted

Whenever the key is turned on the EFI controller runs the fuel pump for a couple seconds to prime the fuel rail that feeds the injectors. That's the whine you hear.

If the engine dies when braking with a low tank it may indicate a problem with the pickup, fuel pump, or related fuel tank issues as barton664 said, or contamination in the fuel settles as the fuel is used. Here's a Link to a comprehensive fuel pump troubleshooting guide (post # 8) that will walk you through the electrical end of things.

How was the bike stored? Was it prepped or "put away wet"? Come to think of it the problem may be a loose or corroded battery terminal that is interrupting power at just the wrong time, but why it would happen only with a low tank is beyond me.

That's as far as I can go with the information given, so look things over and get back to us.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.
