Time to assemble the pistons. Bought a kit with piston, circlip, bearing and the pin.
The procedure is wery much the same as shown in my GT750 post some years ago:
Please we aware of some differences: For the GT 380 all three pistons are identical. There are no washer in the piston as on the latest GT750 models, only the circlip to keep the pin in position.
Pictures from the GT380:
Remember to move the circlip gap at the opposite position to the groove, picture 3-4.
Insert the last circlip and you are done (picture 6 )
