I would start out just doing the 3 turn out on the fuel screw. If you are not going to open the exhaust or modify the snorkel, the stock jetting may be OK. I have the 3 turn out, Z1 exhaust mod, UNI filter, 42.5 pilot and 130 main. Snorkel has the bottom section cut off and I added (2) 1" UNI filter plugs to the side of the airbox. Runs perfect at our 1200' altitude.
As I said, do one thing at a time.
