That sounds more like a carb issue, perhaps idle circuit. Are you sure you got all the carb passages cleaned out? Fuel or starting fluid sprayed into the carb while trying to start may give an idea if it's not getting gas.

I personally haven't done a valve adjustment on a '07 KX450F but I wouldn't have a problem tackling it. The manual as well as YouTube videos should give you a good idea how big a job it is.
