PLEASE OBSERVE THE FOLLOWING NOTES:
1) ALWAYS DOUBLE CHECK CAMSHAFT TIMING BY
USING A HIGH QUALITY DEGREE WHEEL.
2) ALWAYS DOUBLE CHECK YOUR PISTON TO VALVE
CLEARANCE. CHANGING CAM TIMING CHANGES
PISTON TO VALVE CLEARANCE.
3) IF THE BELT DRIVE IS GOING TO BE OPERATED
IN AN ABRASIVE ENVIRONMENT, WE RECOMMEND
COVERING THE UNIT TO PREVENT EXCESSIVE WEAR
TO THE PULLEYS.
NOTE:
ON SOME AFTERMARKET RACING BLOCKS,
ADDITIONAL BLOCK CLEARANCING MAY BE
NECESSARY. WHEN INSTALLING THE BELT DRIVE
SYSTEM, TEST FIT THE COVER TO SEE IF ANY
CLEARANCE PROBLEMS ARISE AND MACHINE
BLOCK AS NEEDED.
