A friend just brought home his new 04 WR450, without changing anything it starts so much easier and quicker than my 03 with all my jetting changes. Do any of you 04 owners know what the stock jetting is? or any other changes they made to make it start easier?

72 starter jet does wonders for easy starting in colder weather! :)

I got the 72 starter jet and a 160 main and a 48 pilot jet and all the other free mods, but the 04 still starts with just a touch of the button, thats why I was wondering if the 04 has differnt jetting than we're running or if they did something different to the carb.
