- camshafts for use with CATCAMS slipper kit (cam lobes are not compatible with other rocker arm systems)
- cylinder head need to be machined to fit the rocker arm system (service available from CATCAMS)
- order 55065xx if vvt on intake needs to be deleted (2 adjustable cam pulleys)
- order 55066xx if vvt remaines operational (only 1 adjustable cam pulley on exhaust camshaft)
#
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
#
- valve clearance is to be adjusted using mechanical lash caps
-
please make sure that the lash cap does not touch the valve locks !
