Machining of spring base diameter required!
REMARKS :
#
These camshafts can only be used for engines without VVT system. They cannot be used in engines with VVT system, even when the VVT system is disabled
#
FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:
-
the camshafs must turn smooth in the cylinderhead, provide free travel by machining where needed
-
distance between valve seal and retainer at full lift must be 0.6mm at least
-
minimum valve spring travel of 1.0mm at full lift must be provided
-
distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15┬░ before TDC on exhaust, and after TDC on intake
#
ONLY for use in competition engines with independent engine management (throttle position sensor) or carburettors
