Today's work. Boring a cam bearing out to late model.
Mr Einstein doing what he does best. Making a mess. Looks awesome. The pro deep in it
How much does it cost?
07 and newer I guess
Booooooorinnnnng, you got anything cool you are doing?
What is the difference between the early cam bearings Hyperformance ??
You did that for me a year ago. All the work was phenomenal and it is a running little beast.
How about the other way? Do you still have the press on sleeves for the early cam to late cam conversation? Thank you...

Brad Cherry block off plates for TC and M8's.
Nice! I ordered a red set from a place I won't mention but the Hbeam rods would not fit in its designated slot. They have small magnets in them. I could have heated them up and shaped them but it was just to many negatives and what ifs for me to use them. This is what I currently use. I'll be giving randy a call for these!
Still room for a piston pin clip to get through and down to the lower end. I'd still put rags in there.
Will these work for 124 TC bores and are cutouts large enough for CP and Darkhorse rods

Yoo, hone boy.
Randy builds the best stuff, he did my machining and head work!
Bit shy with lube in my opinion 🫡
My friend a mechanic took block head motor top end off just to look and to reassemble he honed the barrels I picked up to inspect-next he calls ma back the oil from my fingers left finger prints on inside of barrel
Rottler hone?👍🏻
Sounds like the terminator movie.
The shizzle.
Sweet
Plugging away.
What ya makin Randy? I got mine. Working on a test plate now to introduce the air.
Check your pistons oil jets without removing the cylinders with a differential gauge from the cam side on TC or M8 engine.
Should work on m8 as well. Where can I order a set?
Need a set! Call them! Randy, very smart 👌
We now have a tool to test the pop off pressure of the piston jets without removing them.
Made my own
I’ll put under the. Why didn’t I think of it category
Curious. 12-15?
Let me know when available!
Thanks from Australia Randy . My friend has your Cylinders on his bike 30 years ago
How much?
Keep us in the loop on final cost and availability
AWESOME
Boost on stock M8 pistons.
Little crispy
I'm guessing more than 6-7 psi...lol
Looks good to me lol lol lol That sucks . I tell people all the time do it right. Spent 20 years engineering and making parts for these bike for boost.
Bet that was fun. Did he win the burn out contest?
Stock crank . If you want power start from the bottom. HD have to much crank run out . Cheap shit
Hmm I wondered how long they’d last ^__^
Surprised it didn’t pull the studs.
Kit manufactures recommend the device that gets rid of knock detection.
Ouch that hurts
Ouch
