Valve Clearance Adjustment


NOTE

Mark and record the locations of the valve lifters and shims so that they can be reinstalled in their original positions.

Valve Clearance Adjustment


a + b – c = d

[a] Present Shim Thickness

[b] Measured Valve Clearance

[c] Specified Valve Clearance (Mean Value = 0.195 mm (Exhaust), 0.185 mm (Intake))

[d] Replace Shim Thickness

Example (Exhaust): 1.600 + 0.28 – 0.195 = 1.685 mm

Exchange the shim for the 1.675 size shim.

NOTICE

Be sure to remeasure the clearance after selecting a shim. The clearance can be out of the specified range because of the shim tolerance.

If there is no valve clearance, use a shim that is a few sizes smaller, and remeasure the valve clearance.

NOTICE

Do not put shim stock under the shim. This may cause the shim to pop out at high rpm, causing extensive engine damage.

Do not grind the shim. Thismay cause it to fracture, causing extensive engine damage.

Valve Clearance Inspection
NOTE Valve clearance must be checked and adjusted when the engine is cold (at room temperature). Remove: Crankshaft Sensor Cover (see Crankshaft Sensor Removal in the Electrical System chapt ...

Hub Bearing Inspection
Since the hub bearings are made to extremely close tolerances, the clearance can not normally be measured. NOTE Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones. Turn each bearing in the hub back and forth [A] while checki ...

Exhaust Pipe Installation
Replace the exhaust pipe gaskets [A] and premuffler chamber gasket [B] with new ones. Install the premuffler chamber gasket to the premuffler chamber [C] until it is bottomed so that the chamfer side faces exhaust pipe [D]. Install the exhaust pipe clamp [E] as shown in the figure. I ...

Exhaust Device
This motorcycle is equipped with a exhaust device system. This system controls the valve in the exhaust pipe and produces stable engine power at low and middle engine speed. This exhaust device is controlled by the ECU, and adjustment or maintenance should be done only by a competent mechanic ...
