4.2 lever change
The higher the ratio, the more apply torque the lever exerts on the band. U need less turns adjust it to. 5.0 = 1.5 turns. 4.2=1.75 turns. 3.8=2turns 3.2=2.25 turns. 2.9=2.5 turns. This is not written in stone as front clutch clearance and the number of springs in it also play a factor in determining the number of turns. This is my experience. The reason the higher the ratio number the farther the lever has to go to apply. Kim
