Idle Speed - Honda CB UNICORN DAZZLER 2010 Owner's Manual

crankcase. In this position, the piston
may either be on the compression or
exhaust stroke.
The adjustment must be made when
the piston is at the top of the
compression stroke when both the
intake and exhaust valves are closed.
This condition can be determined by
moving the rocker arms. If they are
free, it is an indication that the valves
are closed and that the piston is on the
compression stroke. If they are tight
and the valves are open, rotate the
flywheel 360° and realign the T mark
to the index mark.
Check the clearance of both valves by
inserting a feeler gauge (5) between the
adjusting screw (6) and the valve stem.
Clearance should be:
Intake: 0.08 mm (0.003 in)
Exhaust: 0.12 mm (0.005 in)
If it is necessary to make an adjustment,
loosen the adjusting screw lock nut (7) and
turn the adjusting screw (6) so there is a
slight resistance when the feeler gauge (5)
is inserted.
After completing the adjustment, tighten the
adjusting screw lock nut while holding the
adjusting screw to prevent it from turning.
Finally, recheck the clearance to make sure
that the adjustment has not been disturbed.
Reinstall the cylinder head cover, timing
mark hole cap and the crankshaft hole cap.
