The way it was told to me they are that hard on them. That's why this lifter was designed to hold more oil. More of a 'cushion' effect. Whether that holds true or not I don't know. I think with more oil going to the top end it would help on some motors. Sometimes I see motors that are getting almost no oil to the top end. Others are fine.

Larry, liquids can not be compressed. Physics 101. There should be no "cushion" effect when compressing oil unless it is aerated (or the tolerances are so loose there is leak-down). If the oil is aerated having more oil in the larger reservoir would be worse than a smaller chamber. It goes without saying, extra leak-down is not a desirable trait either. Is the bore larger radius or deeper to give this extra volume?

Could it be the chamber is made larger by increasing the inside diameter  :scratch:  which therefore makes it easier to machine to closer tolerances? Then the extra oil would only be an unintended byproduct of the machining a larger radius.   :nix:  It is also possible the larger piston face area would do more work per sq. in of pressure which would / could result in less movement of the piston in the bore on valve lift stroke.

Actually they can.. Even solids can be compressed / stressed.. They just don't obey the gas laws... Your high school physics teacher was lying to you..

Is does as long as the volume is increased and lifter piston diameter not..

Didn't pay much attention in physics but my hydraulics teacher said oil compresses 1/10th of 1%. At what pressure I don't know but that was the number he threw out there.

Larry,
        Would you mind posting some images of both lifters from top and bottom as well please?
Provided they're different in appearance of course, bigger oil holes, body thickness etc.
I have a set purported to be the standard Hylift Johnson.
Haven't used them as the oil holes and finish present poorly compared to the factory "C" lifters.
The higher quality lifter appears better finished in the image you've provided.
I'm a novice at this and appreciate the guidance.
 
Thanks.

Thanks Larry,
                   From the image it seems I have a set of the standard Hylift Johnson Lifters.
They'll be headed into a friends bike.
Thanks for posting the images.
cheers,

I think Topline/Hylift has pulled off what Gaterman attempted to do but couldn't. It is my belief this is the lifter we have been waiting for.
If you don't have a sense of humor you probably have no sense at all.

Hoping so...I just ordered a bunch.
I will have some feedback soon...doing lots of motors right now and they're all getting these.

You should have bought them from me.

 I put Larry's performance lifters in my T/C 124 last night. I pulled out the S&S Premium limited travel lifters...and I must say my valve train went almost dead silent compared to the S&S lifters I was running.
 These lifters amazed me at how much quieter they operate in my engine.  :up: This is by far the quietest my valve train has been to date.

Ray I can't wait to hear a report on these lifters after 5k miles and 10 k miles!

Your valvetrain being quiet is quite a testimony!

Hey Larry...I am under the impression you bench test the lifters you sell...is this so?

No. The bench test is older than I am & not very accurate.
I guarantee the ones I sell.
