REMARKS :
#
- only for engines with VVT system (intake) and distribution with chain
- camshafts for use with original VVT system
#
ONLY for use in competition engines with independent engine management (throttle position sensor) or carburettors
#
Distance between valve and piston should be 1.0mm at least:
-
check 5-15° after TDC on intake
-
check 5-15° before TDC on exhaust
Machine pistons if required. Wrong installation can cause severe engine damage!
#
check distance between valve seal and retainer to be at least 0.6mm at full lift
#
VVT reprogramming, operating range adjustment or even eliminating the VVT system should be considered for camshafts with increased duration
