Re Jetted Carbs

I changed the main jets to 138's. Anyone know how many turns out I should have the fuel mix screws. I know they came stock at 1 5/8. I would assume they would need adjustment with the larger jet? Any Suggestions

The FactoryPro tuning kit instructions say to start at 2 1/4 and go from there. Just out of curiosity, why the move to 138's? Is the rest of the fuel/exhaust system stock? Did you stick with stock 38 pilots? The FactoryPro kit assumes that the pilot stays at 38, then they give you 130, 135, and 138 mains. What year is your bike?
