Got a problem

[400exkid2]

when my 400ex is warm it acts like it is cold it will run for about 30-45 seconds then just die it just started doing this
Any help would be appreciated (sp?)

what do you mean by when it's warm? when you start it the first time does it idle good until it gets warm then it stalls? and does it stall when it's idling or are you giving it some gas?

Do you have an aftermarket gas cap? Check the air vent on your cap, and make sure it is clear. If not, you'll get a vacuum lock that will kill your engine.
Also, check the line from your fuel tank to the carb, and make sure it isn't kinked or clogged. It may allow your engine to run at higher rpms, but once the bike warms up, it may not be allowing enough gas to get through.
