Carb synchronization...
My TT600 factory manual specifies a 7mm primary slide height for engagement of the secondary carb, but further specifies that at full throttle, the butterfly valve in the secondary should be horizontal. I have looked at my TT600 and XT600 carbs, and on neither does this happen; at full throttle the valve plate is easily 2-3mm above horizontal. In both cases the only way to get the horizontal position is to adjust so that the secondary opens at 10mm+ on the primary slide.
I defaulted to the 7mm height, but having the valve past horizontal seems like it would obstruct airflow. What gives?
