2.1.2 Troubleshooting to Cylinder Head

Description

Damage Form

Trouble Symptom of

Component

Trouble Symptom of Motorcycle

Remedy

Cylinder

Head

Carbon deposit in the

combustion chamber

Engine overheats

Clear away the carbon deposit.

Threaded hole of spark

plug is damaged

Air leakage between

spark

plug

and

cylinder head

Engine fails or is hard to start

Repair threaded hole or replace the cylinder head

Seriously deformation

of cylinder head surface

(i.e. the deformation is out

of 0.05mm

）

Air leakage between

cylinder

head

and

cylinder

Engine fails or is hard to start. Engine

lacks power.

Unstable idle speed

Grind the cylinder head surface or replace the

cylinder head

Defects such as pits,

erosion, etc. are found on

the contact area of valve

seat.

Air leakage between

valve and valve seat

due

improper

tightness

Do.

Grind the valve seat and valve

I.D. of valve guide is

out of specification (i.e.

its I.D. is out of 5.54mm

）

Valve

stem-to-guide

clearance is too large

Eccentric wear of valve seat cause air

leakage of valve, hard starting of

engine, and unstable idle speed

Replace valve guide or cylinder head

Locknut of cylinder head

is not properly tightened

Air leakage between

cylinder

head

and

cylinder

Engine fails or is hard to start. Engine

lacks power.

Unstable idle speed

Screw up the locknut
