Please don't get mad.

guys i know you all will get mad at me for posting a jetting thread, but you all seemed bored. :worthy: i honestly tried to find the answer but i guess i didnt look hard enough. any way, my problem is that i have an 04 yz450f and my bike pops pretty bad on decel and then at about 1/2-3/4 throttle it does it. i have a yoshi slip on and the stock jetting with my fuel screw at 1 1/2 turns out. i know my jetting/fuel screw is off but can somebody get me in the ball park of where i need to start? i am below 5000' above sea level, probably more around 3000'. any help would be greatly appreciated. :worthy:
