    Default Fuel Line Air Bubble???

    This morning, I hit the start button on my '06 VN 900. It turned over once, but didn't catch. I decided to wait a few seconds before trying again, and as I do, I hear what sounds like the fuel pump running. I wait until the sound stops and hit the start button again. This time it fires up, so I wait for it to idle down, and I'm on my way.

    A few minutes down the road I'm doing about 50mph and there's a car I want to pass, so I roll back on the throttle and the bike starts to sputter and hesitates in a big way.

    I immediately think:
    1) Bad gas, (I had filled up about 45 miles ago)
    2) Clogged filter
    3) Fouled plugs

    I waited another 5 minutes or so, and roll back on the throttle again to see what will happen. It didn't hesitate, but it didn't accelerate either.

    I tried again a few minutes after that, and my bike acted just like it should.

    So my question is:
    Is it possible that I created an air bubble in the fuel line with the aborted start and I don't have anything to worry about;

    or;

    is this a symptom of something more serious?

    Thanks in advance to all of you gurus,
    Lespaul

    Sounds like something in the EFI system.
    MAYBE a pinched or plugged tank vent, but it fixed itself so not likely.

    Have the dealer run your VIN to ensure that the ECU recall has been done on your '06. Your aborted start is not the cause.

    Thanks Rich!! You always come through. I've already saved money from the info you've given in the past. I REALLY appreciate it, but don't start expecting a kick back!
