my 01 blaster has the following mods that i know of: paul turner exhaust and silencer, moose air filter and possibly a wiseco piston.... but anyways, when it warms up it wont idle and when driven it sputters and dies. but this is only after it warms up. and it is not overheating. it takes a couple min for me to be able to start it again. idk why. it runs really good when its cold and i never have to use the choke. i took the carb off, cleaned it and moved the main jet needle but it didnt change anything. i think its either starving for fuel or flooding but i dont know. im new to the atv world and this is my 1st quad i gt in a trade for my crf80.
