- steel billet camshafts
#
- valve clearance is to be adjusted using mechanical lash caps
-
please make sure that the lash cap does not touch the valve locks !
#
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
#
if required, machine cylinder head and / or use solid shims to adjust spring load
#
ONLY for dirt track applications and pro street use with adjustable engine management or carburettors
#
Before camshaft installation: please remove the cam carriers and fit the new camshafts in the empty cam carriers to check interference with the cam lobes. Modify the cam carriers if required.
