Thanks, bought for my build but didn't get the tubes so couldn't get inners adjusted so put my SE pushrods back in. Gonna get right tubes eventually but didnt know if I was leaving power on the table by not using them.

There is no need for adjustable pushrods on an engine with hydraulic lifters.
I keep reading the one about making cam swaps easier, seriously; how many cam swaps are you going to do?

You have a couple of choices: One, order a set of correct-for-your-combination nonadjustable pushrods (which could take a while to arrive-not to mention the procedure required for correctly measuring for the proper length) or, Two, use a set of adjustable pushrods, follow the correct installation procedure, and have your bike running the same weekend, and with the optimum preload.
The other scenario: You want to do a simple (again, a relative term) cam install, you have the weekend to do it in, and you don't want to pull the rocker covers or rocker assemblys. The solution: use adjustable pushrods. Just cut the stock ones out with bolt cutters, and install and adjust the preload on the new adjustables.
No need for adjustable pushrods? Maybe not. But they sure can make things quicker and easier. And, if properly done, there's no real liability, except for the added cost. But then again, time is money........
It's just like everything else in life, you can do it the hard way, or the easy way. Which is hard, and which is easy, is up to the individual.

Not always the case. There are other reasons to open the cam chest on v twins causing pushrods to be pulled. Cam plate upgrade, cam bushings, tensioners,ect. Whatever the case may be for this sort of service will result in a simplified repair both present and future.

An adjustable pushrod allows the PROPER lifter pre-load, in spite of factory pre-load specs, to help insure quiet engine operation, at full thermal expansion.
Base circle, re-surfaced heads, longer/shorter cylinders are all other large reasons for their use.
