LTZ 400 THROTTLE/DIES

[WidowMaker]

Ok so heres what my issue is.....The other day i ran it out of gas...filled it up took a little while to get the gas running through the hoses again..fired up ran fine.....so i dont think this is realated with that but.(background dont ever hurt)  


Question- When i   try to drop the hammer and gun it. in any gear it will just fall on its face and turn off.. it feels like it is getting worse...i have to go now by giving it 1/16 throttle then like 10 sec later give it another 1/16 of an inch.

Bad gas?
Jets?
Junk in the carb?


           Thanks for the help    ~Widow~

i'd pull the fuel supply line from the carb and verify good fuel delivery prior to mesing with the carb.

There are a number of things that you could do.
1. Check fuel flow
2. Clean Carb.
3. Ignition Inspection

If none of these work then I don't know.
You will probably have to bring your Z400 to a shop [smiley=abduct2.gif]

If there is a filter, clean it or replace it. Look for holes in the fuel line. I had that problem with my outboard once. Found the problem, line came unsnapped from the engine, replugged it, ran just fine. It had the same problem, idled fine, when I gave it gas it would die.

Did you run the bike on reserv? How long was it out of gas?
Have you tried to run it on "prime".
The fuel petcock is vacuum operated. It me be stuck or the vac line may have come of the valve or carb.
