Remove the center cover and spark plug cap.

Remove the spark plug.

Insert a compression gauge.

Open the throttle valves fully and pushes the

starter button to test the compression.

Compression

: 15

2kg/cm

If the compression is low, check for the

following:

Leaky valves

Valve clearance to small

Leaking cylinder head gasket

Worn pistons

Worn piston/cylinder

If the compression is high, it indicates that
carbon deposits have accumulated on the
combustion chamber and the piston head.

FUEL TANK CAP CABLE WIRE

Please remove the front cover to inspect the

fuel tank cap cable wire slack when operate

the fuel tank cap hardly.

SEAT CABLE WIRE

Please remove the front cover to inspect the

seat cable wire when operate the seat hardly.
