Clutch Adjustment (Back-Torque Limiter Setting)
The Ninja ZX-10R engine is equipped with the Kawasaki back-torque limiter mechanism
in the clutch. The back-torque limiter works to reduce the chance of rear wheel hop caused
by engine braking during hard braking and down shifting. The back-torque limiter operating
condition can be changed by changing the total thickness of clutch plates and changing the
number of leaf springs. Try different settings and select the best.
The standard setting of length [A], total thickness of clutch plates shown below, becomes
about 53.5 mm (t 2.9 × 7 pcs. + t 2.6 × 2 pcs.). For this setting the effective stroke of
clutch spring plate during the back-torque limiter operation is adjusted between 0.45 and
0.75 mm.
By increasing the effective stroke the back-torque limiter causes more slip. The
effective stroke increases by decreasing the length [A]. The length [A] between 51.9 and
53.5 mm is available by changing the combination of the steel plates. Replace one steel
plate with a thinner one and try the setting. If the operation of the back-torque limiter is not
enough replace other steel plates one by one.
