All specifications referring to 1mm valve lift and 0mm valve clearance.
Notice: When installing the tuning-cam pay close attention to the valve-to-piston clearance a min.1.2mm at the intake valve at 10° before t.d.c and 1.7mm on the exhaust valve at 10° after t.d.c.
In the case the minimum clearances cannot be met, the valve pockets on the top of the piston have to be milled down
