Today's fun, big bore Evo cylinders.
Cast iron will change the coolant color very quickly. A about a week or so after changing and it returns to that. Maybe Randy should have been more "social media correct" prior to the video.....lol.
Forget about the coolant!! Look at the detail of the craftsmanship.
That’s the ugliest coolant I’ve ever seen.
to all complaining about coolant,,,how do you know what he is even using,,,,plus lets see you operation for producing cylinders from billet???????? just a thought
The 3 13/16 billet iron shovel cylinders for Evo heads you made are still awesome...
We haven't used coolant for 20 years. Venturi air cooler directs -30 degree airstream at point of cutter contact. Added benefit is dry chips for scrap metal. Not applicable for everything but has really worked out at Boeing and changed my business and upped profits.
I can do that on a manual machine
I can smell this picture 🤢
What the heck for liquid is that. Coolant is not just whatever to cool something. Its more scientific than that. Very important.
You have to love how much work a fadal can do.
Looking good
That's the absolute worst looking coolant I have ever seen... I can only hope that's not an indication of thier workmanship... Why would someone even present something like that for public consumption?
Hi Im 83 in May 2025 I ride regularly sometimes 130 miles in the day on either my Harley 1200xx Sportster Triumph Bonneville Kawasaki GPZ900R & my Kawasaki is having its winter service I very often leave home 5 Clock ish ride 35 miles to Earls Shilton riders ride 50 / 60 miles with them & then another 35 miles home this has been in the winter nights
Looks like toilet water !!!
Best in the business!
Sick looking coolant
Great job 👍
Can you make a set with knucklehead bolt pattern?
Suds need changing!!!
I'm already there!
Have did my comment appear on this site ?
Absolutely! The PC Police are on the way!!!....Lol
How big ?
I wouldnt even touch a machine with coolant like this🤮🤮🤮

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!
Will these work for 124 TC bores and are cutouts large enough for CP and Darkhorse rods
Still room for a piston pin clip to get through and down to the lower end. I'd still put rags in there.

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 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.
How much?
I’ll put under the. Why didn’t I think of it category
Let me know when available!
Curious. 12-15?
Thanks from Australia Randy . My friend has your Cylinders on his bike 30 years ago
Made my own
Keep us in the loop on final cost and availability
AWESOME
Boost on stock M8 pistons.

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.
I'm guessing more than 6-7 psi...lol
Bet that was fun. Did he win the burn out contest?
Hmm I wondered how long they’d last ^__^
Stock crank . If you want power start from the bottom. HD have to much crank run out . Cheap shit
Surprised it didn’t pull the studs.
Kit manufactures recommend the device that gets rid of knock detection.
Ouch that hurts
Ouch
Ouch
Bump
I need another set for my Evo XL .
Randy D. Torgeson is the man. Love my Hypermotor.
Always use the best.
I have a couple of these R&R engines running around with very happy customers riding them, not only the power but the smoothness and less vibration than the stock engine had, totally worth the price.
What’s the warranty?

When are you gonna play with the new S&S cases Randy?
Looks like jewelry sitting there.
My 120R loves 6000 .
In the words of the Onceler.... Biggerest...
Happy with the little 883 4 speed we ride 2 up. Has mikuni carb and after market mufflers. What I am most pleased with is it pulls a decent amount of revs at 6,200 where as all the big engines I have ridden feel like they want to rev but are limiter restricted at under 5,000, where's the fun in that lol.
Reggie is the man !!!
Fitner in is the thing
Go big or go home . lol

Wtf ,going to the moon
