If your plugs are wet and/or black you are running too
rich. You will not damage your motor, but you will lose
some performance. If your plugs are white, you are running
too lean and you can damage your motor running in this
way. The amount of fuel and air mixture is adjusted
via the carburetors. The spark plug gap should be 0.60
Valves: The major reason CJ750 sidecars
overheat especially on the 22hp or 24hp engines are
because of misadjusted valve lash. You should check
your valve clearance every 2,000-3,000 kms. Your exhaust
valve should be adjusted to 0.15m/m to 0.20m/m and your
intake valve should be adjusted to 0.10 m/m. One can
tell the valve adjustment being off by clicking noise
or excessive heating up and over heating of the engine.
extremely careful of using staight pipes that do not
have any muffer or dampers. This will cause your valves
to be damaged and also you will not have power at high
speeds or with heavy loads.
you are riding your CJ750 and experience a lack of power
even thought the engine is firing properly and there
is also a chirping or high pitch pulsating blowing noise
your valves might be leaking thus you will not have
the proper compression and lose power.
