Am I using a good jet number for my exhaust?

Here is the setup:

FMF Fatty Gold series pipe with FMF PowerCore exhaust
K&N air filter
260 jet

Is the correct jet being used? This is how the bike came when bought.
 
thats sounds pretty close, i was runnin a 270 with open airbox w/uni, boyesen reeds and bills pipe...mine was just a tad lean so somehwere between 260 and 280 would probly be good for you...elevation has to do with jetting also...im at about 800ft above sea level...
