Wont accelarate on my 1997 yzf600r the bike starts fine with the choke on. once i remove the choke and try to accelarate the throttle it starts to shut off. i change the spark plugs ,drained the fuel tank. its fine with the choke on please help

what color was the tips of the spark plugs when you removed them?  just with what information you gave, my first thing I would do is to spray some "deep creep" found at most auto parts stores.  Spray it in the opened carb as directed on can.  Since you say it runs fine with the choke out it runs, tells me that you have a fuel restriction some where.  Spraying Deep Creek will help this if it is the problem.  If no help, tell me more about the problem.  Does it rev up with the choke out?  Is there any noises when it is running that wasn't there before this problem(like a sucking noise).  Does this model have more than one carb?  Did you drain the float bowl? what color was the tips of the spark plugs when you removed them?  just with what information you gave, my first thing I would do is to spray some "deep creep" found at most auto parts stores.  Spray it in the opened carb as directed on can.  Since you say it runs fine with the choke out it runs, tells me that you have a fuel restriction some where.  Spraying Deep Creek will help this if it is the problem.  If no help, tell me more about the problem.  Does it rev up with the choke out?  Is there any noises when it is running that wasn't there before this problem(like a sucking noise).  Does this model have more than one carb?  Did you drain the float bowl?
