guide remover.

valve guide remover until the circlip
contacts with the cylinder head.
(3) Bore the valve guide using the valve
guide reamer.
REFACING THE VALVE SEAT

After refacing the valve seat or replacing
the valve and valve guide, the valve seat
and valve face should be lapped.

When turning the cutter, keep an even
downward pressure (4 - 5 kg) to prevent
chatter marks.
