Checking the ignition timing
Position the engine at top dead centre (TDC) in
compression. To do this, use the appropriate tools.
Use the holes on the engine crankcase to secure
the tool.
Position the specific tool in the window between
the flywheel pick-up references as illustrated in the
figure.
The arrows stamped respectively on the valve
frame and sprocket must coincide.
N.B.
IF THE TIMING UNIT IS NOT IN PHASE CHECK THE COR-
RECT FITTING OF COMPONENTS.
Checking the valve clearance
-To check valve clearance, centre the reference
marks of the timing system.
- Use a feeler gauge to check that the clearance
between the valve and the register corresponds
with the indicated values. When the valve clear-
ance values, intake and exhaust respectively, are
different from the ones indicated below, adjust
them by loosening the lock nut and operating on
the corresponding set screw, as shown in the fig-
ure.
