Aligning of Valve Timing
•
When assembling the camshaft, always make sure to align the valve timing. If this is
not done, not only will performance not be enhanced when the camshaft is
assembled, it will also cause damage to the engine.
•
The valve timing (event angle) here refers to a crank angle formed from top dead
center when the valve is lifted highest.
•
Use the cam sprocket included in the kit for aligning valve timing. The cam sprocket
included in the kit allows selection of five valve timings. In the case of aligning for the
purpose of attaining a minimum squish height of 0.60 mm, use of the center
mounting hole allows setting for intake valve timing of 105° and exhaust valve timing
of 110°.
•
Valve timing adjustment range can be changed to either ±1° or ±2° relative to the
center mounting hole.
CAUTION:
1. In the case of using a new cam chain, make sure to wear in by assembling on the
cam sprockets as shown in the diagram below. Since the cam chain stretches by
approximately 1° after completion of wear-in, adjust by changing the cam sprocket
mounting positions after re-measuring the cam timing.
