Does the airbox have the lid on it? and does it have an aftermarket air filter?
If you have ditched the lid and it has a K&N or somthing similar in the airbox, start your jetting out at 27.5 pilot,air screws 1.5 to 2 turns out, 280 or 290 mains, if your carbs have the stock needles set them in the 3rd position from the blunt end,if it has the dyno jet or toomey 6 position needles set them in the middle clip position.
32:1 is ok for your oil mix...i run klotz supertechniplate at 32:1 in mine.
