Assembly of Cam Sprocket
By making the assembly holes of the cam sprocket of the racing kit long, the valve timing can
be adjusted within the range of -2º to +6 º (CA) compared with standard timing.
TIP
For valve timing adjustment, refer to the KIT TOOLS MANUAL.
NOTICE
• When fitting the camshaft, use the cam sprockets of the kit and always set the valve
timing to match. If otherwise, no intended performance can be expected and more
over, the engine may be damaged.
• When using this camshaft, use the valve spring set 2C0-A2110-70.
