Hi
The longer jet is the one you want to change go larger as the mods you have done are letting to much air and not enough fuel
Your runnin LEAN
Get a few different size larger jets and do plug chops to fine tune

Being a little richer is always better then being too lean
Take care and ride safely
Yours Hank
