Lifters
So I have a 08 ultra stock 96 motor with true dual rhineharts. I was given a set of like brand new cvo 255 cams less than 5k miles on them. I will be doing all the work and a good friend of mine is a ex harley tech and has installed and dyno tuned a bunch of TC motors while he worked at a local harley dealer. So he says he can tune it with my super tuner pro for free. My question is I am trying to make this a budget friendly install. I will be going in through the top to install the push rods. So I will probably get some new stock oem rods, I just don’t like the idea of adjustable pushrods , mainly because of lock but backing off or something. I have no personal experience with it just Leary if them. My question is a see on amazon and eBay a seller has Hylift Johnson American made lifters for $70 or so. Part number is B 2313. I will post a link in a second. Lots of people recomend s&s premiums or the performance ones and they are either 150 or 250 for a set of them. Anyone have any experience with these lifters- The Hylift Johnson ones.
i will be upgrading the inner cam bearings to the Torrington ones.

no reason other than my bike has close to 55k miles on them and was just going to put new ones in while I had it opened. I also though so it could settle in with the new lifters.

Nothing wrong with QUALITY adjustable push rods and it is certainly easier to cut the old ones out than to go thru the top of the motor, plus I like the ability to set the lash... you are putting a lot of faith in the stacking tolerances. I have adjustable push rods in my 2003 TC88 with gear drive cams and in my 13 Limited with a stage 4 kit... never a problem with either motor as long as you soak the new lifters in oil overnight and pump them up... then follow the directions for the number of turns to set the lifter pre load then a drop of blue locktite on the jam nut...

I agree, reuse the pushrods unless they show signs of damage....
The Johnson Hy-lift are quality lifters... I usually get mine for WFO Larry at Larry's Motorcycle & Machine..

I got my lifters from Larry too. I've done the swap both ways...reusing the stock push rods an with the adjustables. Problem is some cam makers don't use standard lope sizes so the stock push rods aren't correct an you lose a little lift. I did have an adjustable back off an leave me stranded but it was my fault. I went with the S&S an they tightened the lock the opposite of the screaming eagles an I did one the wrong way.

Yeah I would for sure do adjustable push rods if I was going with something that had much higher lift or a more aggressive cam.
with the cvo255 cam considered a bolt in cam I figured it would be easier to just drop the rods in and not have to worry about adjusting them.

The lift or duration of a cam don't affect the length of the pushrods needed. It's the base circle of the cam that dictates the length needed for the pushrods.
If the base circle of the aftermarket cams are the same size as OEM cams.... then the stock one-piece pushrods will work just like with OEM cam... if you want the same preload on your lifters as OEM, which is usually close to .100"
Some aftermarket cams do have different size base circles. Then adjustable pushrods work well, or you can measure and have custom one-piece pushrods made for your application...
I usually shy away from adjustable push rods (personal preference). It's more work, but for my '03 Heritage, I installed an old set of adjustable pushrods. I then removed them, measured them, and had Smith Brothers make me up a set of one-piece rods.... Best of both worlds.. I had a set of quality one-piece pushrods and all my lifters were set to a preload of .140" (another personal preference).

Just my 2 cents. My 2007 Ultra was all stock with 7,000 miles on it. When I bought it. Sounded like some one shaking a can of marbles. Installed S&S adjustable push rods. Now. Sounds like a sewing machine.
