I havent received my service manual yet so i have a few questions, when syncing the starter valves, do you prop the tank up at the front? I have ordered a carbtune pro 4, should have it in a week. I used to sync carbs back in the 80s with a mercury column tool, worked pretty good. Do youknow if this carbtune pro 4 requires any additional equipment to sync a 2003 vfr 800, tubing adaptors etc... also i have read that the 6th generation interceptors have different vacume readings for the 4 cylinders to be synced correctly? Any info would be greatly appreciated. bog
