NOTICE

Be sure to remeasure the clearance after selecting a shim. The clearance can be out of the specified range because of the shim tolerance.

If there is no valve clearance, use a shim that is a few sizes smaller, and remeasure the valve clearance.

NOTICE

Do not put shim stock under the shim. This may cause the shim to pop out at high rpm, causing extensive engine damage.

Do not grind the shim. Thismay cause it to fracture, causing extensive engine damage.
