I recently followed Mike Curry's tips on carb mods. After the
installation of a K&N with no jetting the XX ran horribly, shim up the
needles with a couple of #4 washers and it works great.
A tip:
If you use soft luggage for the odd trip and are worried about how easily
the finish scratches on your bike, try buying a roll of the magnetic
window tinting. It is cheap and available at any automotive store,
cut a piece to fit your rear flank or tank and stick it on a clean bike.
It will take all the abrasions of your luggage and road grime and can be
peeled off instantly to produce a scratch free finish.

you like to know more.
