WHAT MAIN JET IS EVERYBODY USING WITH THE WHITE BROS PIPE AND K&N FILTER SET UP ON THERE PREDATOR. HAS ANYBODY MODIFIED THERE AIRBOX WITH THE WHITE BROS PIPE.

 

With airbox mods - 160 main, lower the needle clip one notch, use 8 to 10 discs.

Without airbox mods - 155 main, leave needle stock, use 6 discs.



This the info I came up with after talking to Rath racing & Superbikes.
