Default lifters and push rods

First time using adjustable Push rods on a 2010 electra glide 96,
Using woods knight prowler lifters with fuel moto adjustable push rods @24 TP
According to Woods instructions, they want .120 to .140 preload
They have provided a push rods travel per turns with 24 teeth = .042 of travel instructions
If I shoot for .130 of preload am I right that's 3 full turns? ( .130 divided by .042 )
I primed the lifters with a oil can, but they want to prime the lifters by cranking the engine over until oil comes out of the lifters,
I know I need to pull the fuse for the fuel pump, What about the coil so there is no chance of a spark?

When the plugs are out, and you have no compression, there will be no spark anyway.

Thanks, Guess I was thinking maybe the ECM would be looking for compression to fire, [not wanting to throw codes,] if that would be possible?

Yes it looks for compression. And you need the plugs out to crank the motor over without draining the battery. So no compression, no spark.

So what if it throws a code. You know what it is and why. Clear it and move on.

Don't worry about lifter prime, fire the motor up. There will be some rattling but it won't last long as the lifters pump up and oil is circulating in the system. .042 x 3 turns is actually .126". Most today are setting a bit more preload; at least .130"; many go to .145".
