440ex Rider
Ok im wondering what's causing my Warrior to back-fire and make popping noises when i let of the throttle? Also when i start it for the first time that day it doesnt ideal and keeps dieing but after a while and gets hot it will ideal good. Whats wrong? Is it the jetting or what?

turn the fuel screw on the bottom of the carb in front of the float bowl a 1/4 to 1/2 turn more out until the poping goes away. You can tune the pilot circuit by turning up the idle to about 2000 rpm and adjusting that screw until the idle is at the highest point and you get no missing or backfiring.
You are lean on this circuit and most like on the main as well.

about it not ideling,, it could be jetting..
but it could also be your valves are out of spec... if there too tight it will not idel untill its warmed up.....

If the valves are to tight you think it wouldn't even start.Originally posted by honda300EXtreme

no it woldnt start easily,, but it would start.... unless his intake valves were way too tight..
its happened to me a few times.... it wont idle but it will start.. and sure enough the intake valves are way too tight...

I think your carb needs a good cleansing. Start simple.
