that each camshaft rotates freely. Do not rotate
either camshaft by more than
5".

Caution
If any components have been renewed, the valve
clearances must be checked and adjusted. Running
with incorrectly adjusted valve clearances may
cause excess engine noise, rough running and
engine damage.

necessary (see page

Refit the cam chain tensioner (see page
3-9).
Valve Clearances
Camshaft, valve, valve shim and valve seat wear
affects the valve clearances. The effect of this wear
is to change the gap between the camshaft and
tappet bucket, causing engine noise and improper
running. If the valve clearances become too small,
permanent damage to the valve and valve seat will
take place. If the valve clearance becomes too great,
the engine will become noisy and will not run
correctly.
