pushrod curiousity
Here is what I'm wondering if someone can assist, does anyone have a set of stock push rods and a set of s&s adjustable rods (not the quickie) in their garage/shop ? I would like to know if you turn the adjustment all the way down so the rod is at its shortest length..... is the difference in length to the stock rod equal on all four ? Because it should be in my opinion if the adjustment for all four rods is equal (4 turns) . We know the length on each one is different and must go back where it came from, so the adjustable rod must be compared to the one that it is supposed to replace of course. I would have done this if I thought of it at the time but too late for me. If someone could and is willing to do this, great !!! if not,then I will remain curious I suppose...

It doesn't matter, the length of the adjustable are set to length during the set-up phase. Then the four(4) turns are applied to finalize the length.
In order to not disturb the heads on my bike I cut the factory non-adjustable push rods out, and installed the others in accordance with the manufacturers recommendations.

The four I installed in my bike all had to be adjusted to there shortest length in able to be installed without removing the heads or lifters. They were not marked as to which one went where, but this may have just been the brand used.
They were then adjusted to Zero(0) lash then extended the four(4) turns out.
So if each was adjusted as instructed they in fact were not the same length after adjustment, but were interchangeable before installation.
I think (from the OP's remarks) that he wants to pre set the length, to ease the installation.

From S&S instructions

NOTES:
•
S&S Quickee Pushrods for all big twin engines contain two
long and two short pushrods. All Sportster® model and 1999–up big
twin pushrods are the same length.
•
If S&S® adjustable pushrod kit contains four different length
pushrods, the longest pushrod is for the front exhaust, next longest
is the rear exhaust. Of the two shorter pushrods, the longer one is the
front intake, the shortest pushrod is the rear intake. The pushrod kits for
the 1999–up big twin engine have two different lengths—short for the
intakes, long for the exhausts.

Apparently the way I worded the first post caused confusion, my rods are in the engine, I'm not looking to preadjust them and install. Quikee may be different I think, I'm pretty sure all my adjustable rods were each a different length at their shortest length. They were installed according to instructions from s&s . I will try to reword it differently.... if you take the longest adjustable rod at its shortest length and count the turns to equal the longest stock rod...and then do the same thing for the shortest... did it take the same amount of turns to equal the length of the short rod ? And the other two rods also...
Example : if all four adjustable at their shortest were exactly, say, a half an inch shorter than each of the stock rods they are respectively replacing, then the answer to my question would be, YES, they all need the same amount of turns to equal a stock length push rod.
I have a feeling they are not...

As I read this thread I am glad I went through the trouble to remove the rockers and just reinstall the stock pushrods. All this turning and adjusting and different lengths sounds like a PITA.
