+ | ==== Using a TDC Whistle ==== | ||
+ | |||
+ | Basically, you install whistle in the spark plug hole, rotate the engine and wait for the whistle to blow. \\ | ||
+ | There is a distinct difference in the sound of the whistle between the 2 TDCs from your finger. \\ | ||
+ | Just like the finger method above, a TDC whistle only works when disassembling. \\ | ||
+ | (or rather only works if the pushrods are installed) \\ | ||
+ | It doesn't work when assembling. \\ | ||
+ | Every up stroke has compression when assembling and the valvetrain isn't hooked up and working. \\ | ||
+ | See procedure for [[techtalk:ref:svcproc22#find_compression_using_a_tdc_whistle|Finding compression with a TDC whistle]] in the REF section of the Sportsterpedia. \\ | ||

+ | ====== Spark Plug Hole Adapters ====== | ||
+ | |||
+ | **For Dial Indicators and Piston Stops**: \\ | ||
+ | |||
+ | You can break the ceramic out of a spare spark plug and drill / tap the side walls for screws. \\ | ||
+ | Then insert a 1" dial indicator in the middle of the plug. \\ | ||
+ | The indicator is a slip fit in the middle of the hole and then snug the screw up against it to lock it in place. ((Ranchero50 of the XLFORUM http://xlforum.net/forums/showthread.php?t=1846392)) \\ | ||
