tappet adjustment
 

Near as I can tell my pushrod are 24 threads per inch. I came up with 2 and a half turns adjustment. Any thoughts?

1996 80 inch

0.140" from zero lash is considered the goal.

Thanks, I thought the goal .100, u like them longer because. I've been called a troll so I hope I don't offend by asking.

If you are not sure what brand PRs you have, then make sure you count how many threads in one inch you have to be safe. Adjusting them longer than .100 will reduce valve train noise.

The 0.140" came from the professionals..here are my notes..(s&s adjustable rods, 32 TPI). I've tried these settings , 0.1352" , 0.1456" , 0.1612" , 0.1404".....ev27 cam still makes for a noisy top end at all of these settings, I blame it on the crap screaming eagle lifters I bought.

Don't even know who makes them for HD. That's the scary part....

Yea 24 Tpi=20 flats=.138"

The EV27 cam has very fast opening and closing ramps to get a lot of lift and relatively short duration. No matter what you do it's going to be a noisy cam. At least in my experience.

They are Jim's, HD started to try to unload them because they were overpriced and sat on the shelves.

.100 is the factory lifter setting, this depth will work for 80% of aftermarket cams. Woods, Redshift, EV27 has "square" lobes that shocks the Evo push rod system. A Evo cylinder and head can grow .030 with heat expansion, a sqaure lobe cam can expose the changed lifter when it goes to the looser side depth by clatter. The deeper plunger setting in the lifter covers the expansion plus taming the noise created by the race profile cam
