I added a full FMF Fatty exhaust with K&N and open air box. I put 340 main jets in and set the air/fuel screw 1.5 turns out. It seems to be running great.
This weekend will be my first time to REALLY ride it since the mods so I will post if I find its off.
Check out this link. This will give you all the info you should need and then some in regards to jetting.
Hope this helps.
