Triumph Daytona 675 Manual page 9

Running the engine at less than the minimum recommended squish height can lead to the
pistons contacting the cylinder head, causing major engine damage. This could cause loss
of motorcycle control and an accident.
1. Remove the existing cylinder head
gasket in line with the procedures
detailed in the Daytona 675 service
manual.
2. Position a piece of solder (with a
diameter approximately 1.3 mm) on
the four squish surfaces of each piston.
Position the solder in line with the
corresponding squish surfaces on the
cylinder head and hold in place with a
small amount of grease.
3. Refit the cylinder head with the head
gasket.
4. Slowly turn the engine over, by hand,
to compress the solder to the same
height as the squish clearance.

Warning
5. Remove the cylinder head and head
gasket.
6. Measure the compressed thickness of
the solder. The squish clearance must
be a minimum of 0.65 mm. If the
thickness of the solder is less than
0.65 mm repeat steps 2 to 6 with a
thicker head gasket until the squish
clearance is at an acceptable level.
NOTE
• In some cases, it may be necessary
to use a standard cylinder head
gasket
squish clearance.
7. Fit the chosen cylinder head gasket
following the procedures detailed in the
Daytona 675 service manual.
