Mixture screw setting?

I have a 84 zn700. What should the mixture screws be set to? I have a Kawasaki manual but all I can find is that I'm supposed to count the numbers of turns in so I set it back to that setting. The caps have been removed by someone before so I'm sure they have been adjusted in the past. I'm just looking for the correct factory setting. Thanks!

2.5 turns from lightly seated is a good starting point. After the engine is running well and you vacuum sync the carbs, then fine tune the screws until you achieve the highest idle speed.
