ASSEMBLING AND TESTING THE ENGINE
Insert the gear, then mount the fork-fork pin 
assembly, whilst ensuring to first insert the 
fork into the path of the specific gears. Then 
turn the fork-pin assembly outwards for the 
bolts to remain in the casing and not enter 
their housing. 
CAUTION!
Each  fork  is  marked  with a symbol  that 
must face the casing. 
The  forks  must  be  applied  according  to 
the mark indicated in the images. The 
upper  part  of  fork  “A”  is  higher  than 
fork “B”.
Insert  the  desmodromic control  1 and turn 
the  fork-pin  assembly  inwards  for  the  fork 
pins to enter their respective housing in the 
casing. For this to occur, the guide pins 2 on 
the forks must engage with the slots on the 
desmodromic control.
To  verify  that  all  operations  pertaining  to 
the reassembly  of  the  gear to  the  casing 
function  properly  you  must  simply  ensure 
that the toothed wheels turn freely.
