          7. CYLINDER/PISTON                                          Pulsar   CK   125


 Measure the piston pin O.D.
 Service Limit: 14.96mm replace if below




 Measure the piston O.D.
 Take measurement at 10mm from the
   bottom and 90° to the piston pin hole.

 Service Limit: 56.3mm replace if below




 CYLINDER INSPECTION
 Inspect the cylinder bore for wear, scratches
 or damage.
 Measure the cylinder I.D. at three levels of
 top, middle and bottom at 90° to the piston
 pin (in both X and Y directions).
 Service Limit: 56.6mm replace if over
                                                                 Top
                                                                 Middle
                                                                 Bottom


 Measure the cylinder-to-piston clearance and
 take the maximum figure measured.
 Service Limit: 0.1mm repair or replace if over
 The true roundness is the difference between
 the values measured in X and Y directions.
 The cylindricity (difference between the            Top
 values measured at the three levels in X or Y
 directions) is subject to the maximum value
                                                   Middle
 calculated .
 Service Limits:
  True Roundness: 0.05mm repair or replace         Bottom
                      if over
  Cylindricity: 0.05mm repair or replace if over
