Valve clearance is easy to adjust on all push rod engines or OHC engines with top adjustment using a screwdriver slot and locknut.

Clik-Adjust makes the job even easier and absolutely precise.

This essential clearance adjustment ensures valves (both inlet and exhaust) open and close correctly resulting in better engine performance.

Too little clearance goes unnoticed until valves fail to close and compression and power are lost.

This can burn valves causing costly replacements or even causing an engine fire.

Too great a clearance though not so dangerous results in noise and lost performance
