Metalbender is right, removing the tank makes it easier and it's not hard.
There is a plate on the right hand side that holds the throttle cables that is held by one screw. Removing that screw and releasing the plate will allow you to disconnect the cables.
Loosening the clamps that are fore and aft of the carb will allow you to rotate the carb.
If you have the tank off, then you can rotate the carb slightly to remove the screws in the cap and lift the diaphragm assembly out.
A caution, however. The choke cable terminates in an elbow that goes into a plastic fitting. You must pull the elbow fully out of the fitting before rotating the carb or that fitting will break. Bad juju and a pain in the butt...
If you do not remove the tank, then you will need to remove that fitting before the carb will rotate enough to get access to the cap.
I find that removing the tank takes less time than trying to get that fitting out of the carb.
If you break that fitting there is a metal replacement available that is much sturdier. Perhaps better still, there is a pull-choke assembly from another bike that eliminates the choke cable altogether. I don't remember the bike offhand - it might be the KLX.
Someone will know...(a little help here? Paper?)
