I had my lid off my EX I was spot on with a DJ 170 (recommend by DynoJet) which is like a 190 Keihien. I'm at sea level and if you are a keihein 160 sounds right. And adjust mixture screw.
Also, remember. It don't hurt to be running a little rich, you won't notice a bog. But, running a little lean can cause damage.
