alright guys, i know its a zook, but i am having some problems with my rm-z. its a 2007 450. was running fine. i got it hot one day, was pissin antifreeze out. i let it cool, and ever since it wont start. i got it running the next day, but when i rode it down the street it was acting like it was starving for fuel. it seems to have plenty of compresion, and i changed the plug. i got it fired a couple times today, but it sputters out right away. i pulled the carb off and tried to clean it out, but it didnt seem to help. i dont know much about dirt bikes, this is my first one, so any help here is appreciated. thanks guys.
