1. Select the correct bearing shell as follows:
2. Measure and record the diameter of each crankshaft bearing journal.
3. Measure and record each bearing bore diameter (bearings removed, journal caps
fitted and all fixings fully torqued) (for torque sequence see Crankshaft -
Installation).
4. Select the correct bearings by matching the information found in the bearing
selection chart.
5. Install the new bearings.
Always confirm, using the Plastigauge method, that the running clearance is correct
before final assembly. Severe engine damage could result from incorrect clearance
resulting in loss of motorcycle control and an accident.
NOTICE
Repeat the measurements for all respective journals.
It is normal for the bearings selected to differ from one journal to another.
It is also normal for there to be two options of bearing shell colour. In such cases, pick
the shell size that gives the greater running clearance.
