HECK OF THE TIMING SYSTEM SETTING
To check the engine timing setting, work as follows:
• Set valve clearance to 1,5 mm between rockers;
• Unscrew the engine pinion's fastening nut;
• Fit the hub, Code 65 92 84 00 "2", onto the engine
shaft slot, having fitted the index plate, Code 19 92
5
96 00 "3", and fastening it to the engine shaft by means
of a screw;
• When it is half-screwed down, fasten arrow code 17
94 75 60 "4" to the crankcase threaded hole;

• Fit a dial gauge support "5" onto the LH cylinder's
spark plug hole. Then fit the gauge into the latter;
• Turn the disk in a clockwise direction until the LH
cylinder piston is at top dead center (with valves
1
closed). Reset the gauge and make sure that the
marks (on the timing gearing and on the engine
pinion) "1" are perfectly aligned. Look through the
inspection hole on the gearbox housing to make sure
that the line with the letter "S" is perfectly aligned with
3 the mark made on the centre of the hole;
• At this point align, the tip of the arrow with the "T.D.C."
zero on the index plate,

• Check the setting according to the timing diagram.
• Tighten the support with dial gauge onto the spark
plug hole on the RH cylinder head;
• Fit the control arrow onto the RH side of the
crankcase;
• Turn the disk in a clockwise direction until the "D"
marking is in line with the mark in the center of the
inspection hole on the gearbox housing (valves
closed);
• Repeat the same procedures as for the LH cylinder.
Having completed the test and if everything looks correct:
• Restore the operating backlash between the rockers
and the valves (intake 0.10 mm; exhaust 0.15 mm;)
• Remove the index plate from the crankshaft and the
arrow from the crankcase;
• Remove the support together with the dial gauge from
the hole on the cylinder head, refit the spark plug and
complete the assembly.
