jetting help!

[Spun222400]

i have a 2008 banshee, i am trowing in a ajustable timming plate set to +4 degres, and droping the premix ratio from 24:1 to 40:1, the bike seems to be running rich from idle to mid, and lean at the top,
so im thinking that a larger main will do with the modds am i on the right track i have a phobia of carbs!

the bick runs good now only isue is it hicups sometimes at the top end!
thanks

Go +1 in size f or the main and then reset the needle for the mid-range and idle.
