case as well as damage to the engine.
◎ Always use taco meter to avid over rev.
◎ To adjust valve clearance, you need shim and special tool.

CautionThe following show the envisioned possibility of injuries and damages to human bodies as a result of conduct disregarding
the following cautions.

・Please set the torque at the specified level, using a torque wrench to ensure the right operation.
(Improper setting of the torque could lead to breakage of bolts and tapping section, and coming off of parts.)
・Please work when the engine and the muffler are cool. (Otherwise, you will burn yourself.)
・Please prepare the right tools for the work, and do the work in a proper and right way.
(Otherwise, improper work could cause breakage of parts or injuries to yourself.)

〜 Installation Procedures 〜
Caution : Always use a torque wrench to screw parts tight and securely to the specified torque.
Warning : This Installation Instruction is prepared for those who have acquired basic skill and knowledge.
Therefore, those who are technically inexperienced or unskilled are requested not to do theCOinstallation work.

☆ Please refer with Cylinder Head installation manual.

◎ Remove L side cover and Head cover.

◎Remove camgear and both IN and EXcamshaft.
◎ Install camshaft and adjust valve clearance.
Thickness gauge∴Other than 01-08-072, you can install either IN orEX because it is the same design.

☆Though the shim is available from us, a Honda’s
genuine one is also compatible. For its part No.,
please see the attached sheet.
＊ Be sure to check the size of new shims with amicrometer whether or not it is correct.

◎ If you need adjust clearance,
・Use a valve punner or valve lap to remove valve
lifters.
・When you cannot easily remove shims, use a apair of tweezers or magnet.

PY

・(Keep the removed lifters and shims in an orderly
way so you can see where to reinstall them back.)
・Be sure to reinstall back the valve lifters at its
original place.

∴01-08-072 Install as stamped (IN, EX) of thecamshaft.

Honda-made genuine shims◎ Install valve lifter.
・Attach the new shims to the valve spring
retainer.
・Degrease the valve lifter, and blow air into theshim-mounting portion of the valve lifter to clean
the portion.
・Apply molybdenum disulfide solution to thesliding surface of the valve lifter, and attach it.

◎ How to figure out a size of new shims:
・Wipe off oil adhering to the shims. Measure thethickness of the shims with a micrometer, andtake a note of it.

Figures stamped here

◎The shim is set at 1.20 mm to 2.9 mm, evenly
spaced at 0.025 mm apart.

Ａ：Thickness of the shims to be figured out
Ｂ：The valve clearance measured
Ｃ：The valve clearance to be measured
Ｄ：The thickness of the shim removed

Caution : Be sure to install back the lifter in
its original location.

◎ Attach the camshaft, and check the valve
clearance with the thickness gauge.
For example, you have got a right valve
clearance when you can put ina thickness gauge at 0.15mm
but not at 0.18mm.

○ Positions of Cam Gear and Dowel Pin:

○ Valve Timing Adjustment:◎ Change of the position of a cam gear dowel pin
will make it possible to change the valve timing.
・The lobecenter at each dowel pin position is as◎ Set the piston at the top dead center(TDC)position.
◎ Attach the timing protractor to the crankshaft,and set the protractor dial at “0” and tighten thenut.
Recheck that the piston is at TDC.
(In case it is not right on the TDC, adjust it with aper the illustration below. However, as this is justfor your reference only, figure out the exact angle
with a timing protracter and dial gauge.
