it is necessary to use a shim of 1 mm also
on the locking ring side (POSITION C) before

cover of maximum thickness 1 mm (position A)

at this point the other side of the bottom
bracket must use a non-rotating plate in
position B (between the motor and

POSITION D for the other screw.
IF THE ENGINE IS IN CONTACT WITH CHIANSTAY
Place the shims provided in POSITION A until the engine is no longer in contact with the

(POSITION B & D) to compensate the space used to move away from the frame.
