Total valve lift
Intake Valve 11.40 mm
Exhaust Valve 10.50 mm
25.7° before top dead center point / 62.6° after bottom dead center (Intake Valve)
62.2° before b.d.c. / 21.2° after t.d.c. (Exhaust Valve)
Intake Valve 268.3°
Exhaust Valve 263.4°
Intake Valve 108.4° after t.d.c.
Exhaust Valve 110.6° before t.d.c.
tappet clearance ( cold )
Intake Valve 0.10 mm
Exhaust Valve 0.15 mm
All specifications (angle) referring to 1mm valve lift and 0mm valve clearance.
Notice: When installing the tuning-cam pay attention to the valve-to-piston clearances, a min. of 1.2mm at the intake valve at 10° before t.d.c and 1.7mm at the exhaust valve at 10° after t.d.c. (Minimum distance between piston and valves occurs at 10° before t.d.c (EV) and 10° after t.d.c (IV)).
In the case that the minimum clearances cannot be meet, the valve pockets on the top of the piston have to be milled.
