    recently changed ET sensor.
    put some injector cleaner into the gas, just because
    the bike does sit for a month or so from time to time.

    yesterday, out and about and the engine starts.. stumbling.
    would just miss, all gears all rpms,
    runs fine at idle.

    plugs ok, air cleaner ok.
    pulled the top plate from the fuel tank, looks like some interesting things
    in there, not in the mood to come out yet though.

    first stupid question.. is it supposed to be 'wet' in there ? (gasoline)

    i wonder because of the gasket and 10 screws to get the plate off.

    There are components of the fuel system in there like the fuel pump, sending unit, filter etc that are submerged in fuel but I consider "WET" as water myself. Be sure to replace the gasket and sealing washers on the cover when you replace the cover plate.(one time use only)

    Have you looked at the lowest portions of the tank to see if there is debris or water pooled there that you can remove as long as you have it opened up which could be causing your problem? Any water present will pool at the lowest point and can be siphoned out now with the cover opened up. Traces of rust at the lowest point would indicate that there was water in there at some point if not now.

    'wet' meaning there is a strong smell of gasoline, and there is gasoline on what
    looks like a fuel line.

    submerged in fuel.. meaning that chamber should have fuel in it ?


    i will look in the tank as soon as i can figure out how the pieces attached
    to the top plate can come off.

    Once the cover is removed, that is the inside of the fuel tank and there should be fuel in there surrounding the parts in there.

    [FONT=Arial,Helvetica,Sans Serif]The manual mentions how to remove the assembly, but it's not very clear----If you reach inside and actually push downward on the pump itself, it will then swivel downward which allows it to be removed "fairly" easily. It makes sense once you have it removed.
    [/FONT][FONT=Arial,Helvetica,Sans Serif]The pump, pickup, and fuel sender assembly all can pivot 90-degrees. With it at 90-degrees, the assembly goes in and out with relative ease[/FONT].
    Check the side of the corrugated fuel line for abrasions. They rub on the tank and can wear through causing poor running which may be your problem also.

    ok glider, thank you :)

    i'll have a look for debris and water, i was thinking it feels like water
    in the gas.

    it really is the inside of the tank in there :)

    It should be replaced and not cleaned because you really can't clean anything out that would be beneficial. If the bike has low miles on it, just put the filter back in again.

    17000 miles, dont know if you call that 'low'

    i see the filter is pretty much a self contained unit, nothing to do there...

    ok, so I checked the hoses, they all seem ok, the only thing
    that may have been is that the filter pulled away from the regulator ?
    little too easily, went back together with a little 'click'..

    so I'll put it all back together, and see if its any better.
