When rebuilding the ‘top end’ of your Cobra
motorcycle, care must be taken to ensure the
proper squish clearance. Squish clearance is
defined as the minimum distance between
cylinder head and piston at TDC, and there are
negative effects of either having too much or too
little clearance. Since parts like the crank,
connecting rod, cylinder head, piston, and
crankcases all have varying tolerances, Cobra
offers several different base gasket thickness’ to
ensure that you can always set the squish
clearance of your engine to factory
specifications.
For base gasket replacement use the code (see
figure 21 for location) along with the table on the
following page reorder the correct thickness
gasket.

NOTE:
Tolerances will affect the actual gasket thicknesses.
If during the course of the maintenance more parts than the base gasket are
changed, the squish clearance should be measured, and possibly a different
base gasket will be required.
