Make sure the piston oil jets 

7

 are positioned 

correctly and free of obstructions.

Make sure that O-ring 

9

 is correctly positioned 

by checking its state. Should the O-rings have 

cracks or deformations, they must be replaced.

3.1.3  EXTERNAL LEFT SIDE

Make sure the calibrated screw 

1

 and the jet 

2

 are not obstructed. Should they have been 

replaced, couple them to the crankcase using 

a small amount of medium strength threadlo-

cker, being careful that the threadlocker does 

not block the holes. Then tighten them all the 

way. 

Make sure that the oil passage 

A

 is cleaned 

well. Make sure that the countershaft bearing 

retaining plate 

3

 is not deformed. If it is, re-

place it.

The table below carries the indications for ap-

plication of the screw for the plate

.

The crankcase half will definitely have to be re-

placed if the oil pump crankcase 

B

 has deep 

scratches or signs of meshing
