Anyone know what stock jetting is.

depends on what year you are... i would ditch the air box lid, and get a K&N... i dunno what filter you are running... but i live in Mesa AZ, and when my bike was stock with the paul turner race, wiht a K&N and rad valve, i ran like a 162 main in the winter and that was just a tad rich, and had the needle on the 3rd position... you shouldnt be too far off there...

stock i think is 155...

I had a 38mm carb, pipe, and no lid on the airbox and used a 160 main and like 3rd clip on needle

perform a plug chop so that you'll get it spot on.
