Suzuki DR650SE - Camshaft Runout; Cylinder Distortion; Cylinder Bore; Piston Diameter

3·27 ENGINE
If the camshaft journal oil clearance measured exceeds the
limit, measure the outside diameter of camshaft.
Replace either the cylinder head set or the camshaft if the
clearance is incorrect.
11m 09900-20205: Micrometer (0-25 mm)
Camshaft journal O.D.: 21.959-21.980 mm
(Right & Center) (0.8645-0.8654 in)
Camshaft journal O. D.: 17.466 -17.484 mm
(Left) (0.6877 -0.6883 in)
CAMSHAFT RUNOUT
Measure the runout with a dial gauge. Replace the camshaft
if the runout exceeds the limit.
Service Limit: 0.10 mm (0.004 in)
11m 09900-20701: Magnetic stand
09900-20606: Dial gauge (1/100 mm)
09900-21304: V-block
CYLINDER DISTORTION
Check the gasketed surface of the cylinder for distortion with
a straightedge and thickness gauge, taking a clearance read-
ing
at several places as indicated. If the largest reading at
any position of the straightedge exceeds the limit, replace
the cylinder.
Service Limit: 0.05 mm (0.002 in)
CYLINDER BORE
Inspect the cylinder wall for nicks, scratches or other
damage.
11m 09900-20508: Cylinder bore gauge set
09900-20513: Gauge rod
Standard: 100.000-100.015 mm (3.9370-3.9376 in)
PISTON DIAMETER
Using a micrometer, measure the piston outside diameter
at the place 21 mm (0.8 in) from the skirt end as shown
in Fig. If the measurement is less than the limit, replace the
piston.
11m 09900-20204: Micrometer (75-100 mm)
Service Limit: 99.880 mm (3.9323 in)
