REMARKS :
#
16x CAT017 rocker arm
#
16x CAT018 shaft for rocker arm
#
16x CAT019 support for rocker arm
#
Cylinder head needs to be machined in order to mount the valve springs (create clearance diameter 25.4mm for valve spring outer diameter)
#
Use flat shims to increase the valve spring tension to the suggested load.
REMARKS :
#
- 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)
- camshaft with fuel pump lobe (version without fuel pump lobe: 76027xx)

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
