okay, im sorry for my ignorance, as im sure this question has been asked a million times, and i apologize first, but i need a jetting baseline. im planning on pulling my carb off, and cleaning it this weekend, and i want to know what size main, pilot, what position for the clip etc etc. what should i have in there, or what combo would work good? its a stock carb, and the quad only has k&n w/ outerwears, and no lid, and an lrd pipe and silencer. im currently using amsoil dominator at 50:1, but plan on using it at 40:1 when this tank runs out. michigan altitude. my quad bogs real bad in 1st and 2nd, probably all the way up to 1/2 throttle, after that, its fine, and 3rd through 6th gear are fine. it wont idle, and the idle screw seems to make no difference, im also going through a lot of gas. please help.....

The baseline settings are as follows:
1986= main 150, pilot 48, needle clip 4th groove, air screw 1 7/8 out
1987= main 152, pilot 48, needle clip 3rd groove, air screw 1 7/8 out
1988= main 158, pilot 45, needle clip 3rd groove, air screw 1 3/4 out
1989= main 155, pilot 42, needle clip 4th groove, air screw 1 1/2 out
GOOD LUCK!
