bodyart,

Chain stretch is a misnomer. The increase in length is actually caused by wear in the holes and on the pins in each chain link. Elongation is a better word for the increase in length.

To make the measuring and setting of the valve clearances easy, get .003, .005, .013 and .015 inch feeler gauges and use as go/nogo gauges. Using these sizes will set or measure the valve clearance to nominal + or - .001 inch. Just set the valves on the loose side when using the .003 and .013 inch guages.
