Yes .... They are Hyd lifters ....
But those stock looking lifter blocks are BMO's Velva Touch ....

Image

I did a bit of sawing and welding on them to make em look like Oem and had them chromed ...

Image

Image

Image

I did a bunch of sawing on that motor .. !!
This is what that STD case looked like before my sweat when into it ...

Image

That motor is beginning to look pretty sweet, even if I do say so myself ... :oops:

Image

96 Cubes, S&S P-Series heads, Speed n Science Big-Bore Alum jugs, Carrillo Rods and the dual Riley carbs ... Got a world of goodies in that critter, I'm here to tell ya .... :D

Your most welcome on the sharing deal ... Most of my ideas comes from my peers ...
I should be thanking all of y'all ... :wink:

Oh BTY ....
On the "Mini Me" Air Cleaner .... I have started machining the backing plates ...
Don't have a lot of time to work on my own stuff, so it's going to take awhile before it's done... Maybe by the end of next week .. ???
That's the last bit of work that the "B" carb needs to be able to call it DONE .. !!!

Thank You for the quick reply.
Velva Touch lifters are a bit pricey and since I have a running complete engine the only advantage for me would be the hydraulics, and I've lived without them in my Pan & Shovel since 1967, a few more miles without the juicy lifters should be of no consequence. If I had money to burn and a ground up build I might consider a set, but then again, probably not....
....Best Wishes....RooDog....

Reason for the Velva Touch is their ability to work with radical cam grinds ...
We choose a Bad-Ass Leineweber cam for it, and with those carbs being right in the way of doing 1000 mile adjustments for solid's ..
We made a Hi-Dollar choice ...

That motor build has been 4 years in the build..
What took so long was the wait for the owner to save up money in order to make an order ...

Lots of Hi-Dollar parts are in the make-up of this one...
I use a Quick-Books program for invoicing .... It doesn't tell me the total of what money has been spent .... Only the balance between payments and debt ...

I asked the owner if he knew how much money he put into this project ... ??
He said not a clue .. !!
Told him I could go though his invoice and add it up if he wanted to know ...
He said he didn't want to know, maybe at the end of the build I'll add it all up and faint .... :lol:

Guessing, it has to be over 15 grand ... and here I thought 10 grand that went into this Knuckle build was nuts ...

It has never bothered m to spend the other guy's money to build something nice and trouble free, but for a flipper, one has to watch every cent spent. Also for my own personal projects I am able to save so much doing things myself that I oft times can afford to splurge for the Hi-Dollar stuff, but not for those lifters though. LOL..
I suppose we all have our own way of doing things.....

Being Stainless It'll shine up pretty good ...

And here I thought I was done fooling around with the Super-B ... :shock:

But being the backing plate is made up as a two piece, I did a bit more polishing on the cut-out Super-B part of the plate ..

Image


To lock the two piece backing plate together...
Some Two Ton Epoxy was used..
It dang near could run the way it is... Machined it with a super close fit with a snap in shoulder .. But the epoxy will keep it from coming apart ...

Sure don't want that falling off at over a 100 mph ..... !!

Well Fellas ....
Went from the Siren A/C to the "Mini Me" A/C (In three pages), think it will fit my scoot a little better than the Siren being it's much thinner and keeps the look of old alive .. (Sorta) !!

Here's my take on foam air filters, perhaps your red one will do better. Mine deteriated on the shelf, having not been put into service. After cleaning off the residue I installed a K&N element, they last "forever" in experiance.....

Haven't checked to see if a K&N is available ...
But, being these are $5.95 for a replacement, I might buy up a few ...

The UNI Filters are washable ...
And reusable, I'm going do my best to stay off gravel roads too ...

.../// https://unifilter.com/cleaning-oiling/ \\\...

Uni Filter entered the air filtration industry in 1969 with a simple concept, “Lets design an air filter that works. And that’s exactly what we did. We chose polyurethane foam as our air filtration medium, instead of paper or gauze, because of it’s superior dirt capturing capabilities and its capacity to be easily cleaned and reused. And the rest is history. Our original “SOCK” and “POD” air filters took the industry by storm and led to the most comprehensive line of foam air filters in the world!

Here’s how a Uni Foam Air Filter works: “Open Cell” Polyurethane Foam is wetted with specially developed filter oil. The “sticky” filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam. This makes it impossible for dirt to pass through the depth of the filter without sticking to the strands.
As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness to be utilized. This prevents surface loading or air restriction for 80% of the service life of the air filter element. When the filter is sufficiently dirty, it can be easily washed, re-oiled, and re-used.

RACE TESTED

Uni Filter products perform their best in the worst of conditions. That’s why Uni has been the chosen air filter of all serious offroaders for decades. In this dirty, dusty environment, air filtration is extremely critical to the performance and protection of the engine. The Uni Air Filter’s ability to hold extreme amounts of dirt and still provide excellent air flow and performance has made Uni Filter the choice of some of the greatest racers of all time, including but not limited to: Ricky Carmicheal, Jeremy McGrath, Chad Reed, James Stewart, Ryan Villopoto, Eli Tomac, Grant Langston, Joe Byrd, Wayne Matlock, Ronnie Renner, Brian Deegan, Robby Gordon, Cameron Steele, Cale Yarborough and many more.

Well, Good Golly "RooDog"

Ya got me thinking ...

Image

Had a drilled hole (Came with it drilled) that I was going to fill up with weld, but didn't cause I didn't want to mar the finish that was there ..
Thought about just leaving it open .. :shock:

Where it was at would allow un-filtered air to get to the motor, :idea: so I'm trying my hand with some JB Weld and paint ... We'll see how that goes.. ??

Why don't you use copper mesh? I have that on my S&S shorty E. My pan breathes much nicer.

Got the hole filled in with JB and dabbed a bit of paint on it ...
