NOTE: The cylinder bores should be measured at normal room temperature, 21 degrees C (70 degrees F).
The cylinder walls should be checked for out-of-round and taper with Tool C119 or equivalent (Refer to 9 - ENGINE - SPECIFICATIONS). If the cylinder walls are badly scuffed or scored, the cylinder block should be replaced, and new pistons and rings fitted.
Measure the cylinder bore at three levels in directions A and B . Top measurement should be 10 mm (3/8 in.) down and bottom measurement should be 10 mm (3/8 in.) up from bottom of bore. (Refer to 9 - ENGINE - SPECIFICATIONS).
