[This was my first time asking this question] This is a 2000 Kawasaki KX-60 with a 2-Stoke motor. The motor has low hours. It has been sitting for approximately 2-years. Before it was stored it ran perfectly. The problem i'm having is, when i start the bike with choke, it idles and runs fine - but when i turn off the choke the bike runs for about 2-3 seconds before bogging out. I figured it must be a dirty carb...so i completely cleaned the carb and jet/pilot jet (did it twice). Unfortunately, it didn't work...the bike is still doing the same thing. I'm not sure if the reeds would potentially cause something like this - i would say "No" because the bike is only affected by the choke, so that tells me its in the carb.
[Part 2] Since asking this question, I've replaced the old fuel with fresh gas (32:1 mix) , installed a new spark plug and air filter; but the motor still bogs out with the choke off.
This is really unusual - your help is appreciated.

--One more time, clean your carb. With a spray can of carb cleaner, spray through each hole in the carb. You'll know that it's clean if spray comes out another hole. Hold the pilot jet up to the light, you should be able to see through it.
--As long as the carb is off, remove the reed block and make sure the reeds are sealing. You shouldn't be able to see through them (I doubt if that's the problem, but it couldn't hurt to check). Install new gaskets.
--Check the float level (I doubt it would be off, from just sitting). Remove the float bowl. Turn on the fuel. Lift up the floats by hand. The fuel should stop flowing when the float arm is parallel with carb/bowl mating surface.
--The crank seal on the flywheel side could be leaking due to sitting through hot/cold/hot/cold weather. Air would enter causing a lean mixture. Turninng on the choke would compensate for the problem. Changing the crank seal is fairly simple. Remove the flywheel with the correct flywheel puller. Pull out the seal and tap in a new one.

--Your last resort, something to do with the piston and rings. The rings could be frozen to the piston. Remove the top end and take a look.

If the bike has been sitting for 2 years, most likely the gas has "varnished". Replacing the gas is good, but you need to clean the carburetor. If it only runs on the Choke circuit, I would say that the Main circuit is plugged. Take the bowl off the carb and remove the main jet and emulsion tube and clean it in clean gas. Make sure the air ports are clear aswell. They are on the front of the carb by the air cleaner.

Your crankshaft seals are bad,you are sucking air through these seals.I've seen this several times and people automatically blame the carb.The bike will never idle until this is fixed and if it does run it will overheat from running lean.The gas and oil mixture left in the crankcase for two years makes the rubber seals jelly like.The seals are double lipped because they have to work under pressure and vacuum conditions.When the piston goes up it pulls a vacuum on the crankcase to pull the fuel mixture in,when the piston comes down it pressurizes the crankcase to push the mixture on top of the piston.Hope this helps,I've worked on bikes for 31 years.

try setting the slider needle richer,moved up,try one notch at a time.
make sure your exhaust baffles are not plugging off when hot

chech the float it might still be sticking,or adjust airflow I guess it do the same thing when you open the throttle or it jokes out
