"Cyclone". In the 70's I wanted something I didn't need, polished intake on my Pan. Don "Gramps" Smith put me wise to the rough intake surface that mixes air and fuel more efficiently.
And I polished (mirrored) the intake ports on a flathead Merc V8. After that, idling was impossible. Live and learn. Maybe we can keep the younger guys from experiencing the stuff we did wrong.
If you had suspenders and a belt on you would be a dead ringer for my stepfather. He left me a 82 FLH.This bike has been to Sturgis over 20 times. I used this bike to pass my ND road test. The instructor kind of chuckled and wished me good luck. I was the only one who brought a big bike. Passed with no deductions. The bike has 80,000 miles and I ride a few times a week. I really enjoy the shovelhead videos and look forward to keeping my bike on the road for as long as possible. Thanks Mike keep up the great work.
Interesting! I've never seen a "textured" intake. Have seen dimpling though (looks like a golf ball); what a trip. Those engine gurus are total freaks! What a cool group of dudes.
Yes they are. It's textured to match the intake ports. That way, it is matched in size and gives a consistent flow all the way through the intake tract.
Brain cramps ....get them all the time... think its part of this getting older stuff....Gotta be tuff to get old...Beutiful top end work thanks for sharing...
Beautiful work....a work of art....this is so much fun!!... Thanks for posting....as someone else said...thus is the only YTvideo you can click the " like" button before you see the video
Thank you Mike for another interesting/informative video. When Victory motorcycles were being introduced to the market I worked as a CNC machinist on the heads. It took three Mazaks doing different operations on the castings. The valve seats and guides were cooled in liquid nitrogen. The castings themselves were heated in ovens. The seats and guides were then pressed into place before the being machined. The heads were oil cooled and air cooled. Interesting design and very close tolerances. Total tolerance for the guides was 0.0003. I have one of the early heads that was scrap. Dumpster Diving. Lol
Those pistons are almost to good to use in the motor and should be on a shelf in the home bar. Loving the videos keep it up. From a young buck down under
love your video's,,,,,and Bikes,,,,,,GasFlowed head is what we call it in UK Real tuning ! Beautiful Heads & Pistons, sure Jim's gonna love the torque its going give him longer arms Greetings from Wales
Vaporizing the air / fuel mix, Mike. I get a lot of "brain farts" too ; think it,s all this covid and isolation Those heads ,cylinders and pistons are sure things of beauty!!!!!!!!!! Look really efficient. Thanks for the great video. Stay safe.
I am really liking my Evo it is a very good motor. I had two twins cams and sold them both after seeing some major failures in other guys twin cams. That is a beautiful motor Mike I'm looking forward to more videos as you finish it.
When I bought my shovel many years back . . from an dealer actually , they claimed it had an cam . . I nodded & smiled as I knew those things were important to the motor functioning
Thank You. I'm sorry to hear about your difficulties. I closed my shop just a little earlier than you. Perhaps we aren't supposed to work that hard for too long.
Love the polish work on the heads, lot of people think that the intake side needs a high polish, but there wrong, as you said, you need the texture on the intake side for good fuel suspension and atomation and the exhaust high polish to get that exhaust gases out freely and unrestricted
Very nice. I don't think my current block could take a whole lot more building up. Nor could my little softail frame handle a bigger motor, but it would be fun to take on a project like that. My bike "Donna Sue" is past due for a teardown and painting, sadly due to Oregon rust gremlins. Thanks to your block painting advice from this series one day I'll be able to get her cleaned up. 7700 miles and she's a 2001 looks the part of 18 years old but runs like a brand new bike. She should look the part again. Man oh man I love bikes.
Intake ports have that hump on the floor probably to raise air speed and provide a short turn radius. The exhaust looks like it may have been extrude honed. Lots of r&d there. Nice!
I just sold a brand new set of Branch O'Keefe heads that looked similar to those. They were very beautifully done. I chose to sell them because they also required a proprietary set of pistons
@@pacificmike9501 I just like my flat tops and not into the whole hemi thing. I give that up years ago when I built my Shovelhead and Sportster motors. The heads are very nice although when I was told they'd need special set of proprietary pistons to make them run I quickly sold them.
Mike I have an interesting one for you. I have a 1998 electra glide ultra classic. 33,000 miles. As far as I or anyone else can tell, all engine components are original. I was getting a top end noise ( I had asked you a few questions here on your videos regarding this ). I ended up replacing the lifters and pushrods, andrews ez install pushrods. Still had the same noise. After much going back and forth, I pulled the rocker boxes. When I opened the front rocker box, it was immediately apparent the intake valve retainer was hitting the rocker box and the rocker arm was hitting the retainer before touching the valve stem. I ended up measuring the height of the intake valve compared to the back cylinder. It was many thousandths taller. Hummmm ? Pulled the heads and cylinders. Pulled the front cylinder intake valve. The keepers for that valve were mushroomed and full of fractures. With the keeper being mushroomed, it allowed the retainer to slide up the valve stem. Causing the retainer to contact the bottom of the rocker arm. With the rocker arm not pushing straight down on the valve, it wash pushing the valve sideways and causing it to contact the rocker box. I took all my parts to my local full service bike shop, Heads 1st performance in Westville Indiana. When he pulled the rest of the valves, the keepers for all the valves were full of fractures. I have not talked to anyone yet that has ever seen or heard of this happening. Have you ever dealt with this ?
Today, things are a little different than they used to be. Manufacturers give out lots of information. Way back when, everything was an experiment. I don't know that I've seen this one exactly, but it sounds like someone installed a cam that was not intended to drop into a stock motor. Consequently, without all of the clearance issues being addressed, things collided.
Love your videos especially on evo work on jims bike. As a young man nearly 60 i have a 1988 softail. I do as much as possible for my bike. Currently i am putting a stroker kit in my evo from 80" to 89" not as pretty as your heads. Keep up the great work. From south Australia Gazzar
When I was involved in engine building (forty+ years ago), porting the ring lands was a new thing. Or am I scattered as well? Anyway, I did notice those most impressive pistons appear to be ported, yes?
These are very "high tech" pistons. One of the ring lands is grooved. I leave this to the experts. Today's pistons are so superior to the stuff we used to have. I went to a seminar on piston rings once, and the technology was so intense, I got dizzy.
HOWDY MIKE, it has been as high as 80 F degrees here in INDIANA in APRIL so far in 2021 ... but TODAY the Weather Guessers & Drama Queens are forecasting 3" of freaking SNOW !!! ( 04/20/2021) So - today - I get to watch You-Tube VIDEOS = thank YOU for POSTING COOP .......................................
The Universe! I recently bought a 97 Faboy evo as well! My engine is just a bit sassy. The ignition doesnt work properly. Especially if its cold outside. But overall she is absolutly beautiful and i love her. Could you do a video on how to adjust the ignition. Or maybe u know this problem and can tell me? And excuse any grammar or spelling mistakes. I`m from Europe and my english is a bit rusty.
Are you sure it is the ignition. Step one: remove sparkplugs. Step two: Compare sparkplugs. Step three: If one is dark and one is light, that is, they don't match, you have a manifold vacuum leak. Check that first.
That one is finished and in our list of videos. Go to our TH-cam homepage and click on the word "videos." There are over 20 videos on that particular bike with it's engine modifications. And, we start it and let it run.
Hey Mike your my favorite channel. Thanks for your great work. I have the 2001 Duce and the starter was making that noise! I changed the parts in it but now it makes noise while driving does get quit as the bike warms. I have chosen just to buy a new chrome starter hopefully fixing this noise. I love my bike have another in Greece 2007 Dyna Wide Glide.
You're sure it's a starter noise? Maybe it's a compensator or even the primary chain. Have you adjusted it lately? Are you sure the compensator nut is tight?
@@pacificmike9501 Thanks Mike I tried to locate it , I found it comes right were the small nut is to remove the starter inside the primary. I did check the other parts they were fine only 12, km on the bike.
Wow! What do this kit? How much it cost? Where I can buy it? Cant wait when you make a upgrade for Big Jim. And wanna listen a shovelhead start up, maybe po-ta-to sound)) Thank you!
Those pistons look awsome.! I didn't have the $$$ so I used JE flats on my hemi shaped chambers. I know im loosing performance but I plan on dual plugs since I want to stay at about 10-1 comp.
@@pacificmike9501 I've decided or been advised that the dual plugs don't really help for my Frankenstein combo. Later on im just going to get S&S slugs to match the chamber. Might as well get all the available performance.
The tapers in the flywheels are moved out from the stock location. Today, we do this by using stroker flywheels. We're using Truett and Osborn's I installed years ago into this motor.
Really nice parts I have purchased a set just like that from Jerry branch in California and I am super impressed with it although I think the Dave Mackey set looks to be a little nicer
Different. Each one of these guys does it their way. You ever notice how many brands of camshafts are out there? You pick and choose and come up with what you like.
You're as bad as I am. That one was fun. How about this one. Let's see, more duration here will improve my cruising speed, but this one will help me blow off that group of guys. Maybe this one would pull better in the mountains. That one was great, but I never rode fast enough for it to kick in. I love it.

Atomizing the fuel. I love the parts, they are beautiful.
Yes! And, Thank You.
I think we are all scattered. If you keep the wheels rolling, the projects will finally get done. Keep up the great work.

Glad you like them! Years ago, I got my heads done like that. They were on the coffee table for days. I just wanted to look at them.
Thank You Mike for each video
Thank You for watching.
You can see the quality of the workmanship very nice job.
Yes, this went to professionals at what they do.
Those are some gorgeous parts.Thanks for sharing.Can’t wait to hear that thumping Evo👍.
You and me both! It will be a few weeks 'til I can get the bike here.
Thanx, Mike!

Thank You. The word "atomization" wouldn't come up.
Can't wait for Jim's build, always love stopping by the garage have a blessed week my friend.
Thanks, you too!
great looking set up
Yes it is. They did their usual stuff.
Beautiful parts Mike, I'm looking forward. Thanks for sharing 👌👍
Glad you enjoyed it. Thank You.
Thank you

Heads look amazing,Real nice work Mike
I didn't do them. But I love 'em.
THANK YOU...for sharing. Some really great-looking parts, like those pistons too! Going to be one fast stroker motor.
Thank You. And, yes it will be.
Circling back around to look at those beautiful parts. Lovely.
You bet. Couldn't happen to a better guy.
Great video Mike! I have a 96' Heritage I wouldn't mind massaging....
Yes, it is highly contageous.
Oh man! Sooooooo excited to see those in person Mike. They look stunning.
They are! See you soon.
That was smokin hot mike that motor is gonna hum nice job
Yah.
Mighty fine polish work! It all looks good!
Yah, it's way cool.
Looking good Mike !
I didn't do it. And, it's not for me. But I love it.
I went to Dave Mackie website, and if I ever do another motor, it'll be through his company for sure. Beautiful, awesome work...
Very cool!
You stay healthy Mike....we need to hear that engine fire...!!!!!....stay safe bro...:)
Thank You. And you too.
Another excellent video Mike . Thanks
Glad you enjoyed it
Mike the work looks great can’t wait to hear it run when it’s finished
Thank You. Me too.

That evo build is going to be sweet.
I think so. Thank You.
For sure
My hat off to you brother I'm 65 had to shut my shop down due to back failure.👍 keep up the good work.

Great work Mike!
Glad you enjoyed it
Simply gorgeous 😍
It really is!
A friend had similar head work done on an 88" Shovel. It was amazing!!!!!!
I'm sure it was.
That is going to be an impressive build.
It's gonna be fun. I've done this one a few times. But this is the first combo of this stuff in an Evo stroker.

Yes, some really nice work.
The parts scream speed can't wait on the build.
Me too!
thats some insane polishwork on the head, very nice
It's really good work.
Was atomize the word you were looking for? 🤔 thanks for the videos always

True. Thank You. At my age, I reach for words that don't always pop right out any more.
Man that’s some good work. Parts look fantastic
They are
great vid, Mike.

Atomizing I think the word you were trying to find. I enjoy your videos
Yes! Thank you!
Looks like jewelry... Beautiful!!!
Yah, I sit and look at them.
All this is very nice.
Glad you think so!
ATOMIZING....others beat me to it...Old Guys hanging together...😄😄😄

I said where the work was done. You can find it on line. The Shovelhead is a little to nasty to do the "potato" real nice. Kinda raspy.
Those pistons look awsome.! I didn't have the $$$ so I used JE flats on my hemi shaped chambers.

Sounds interesting. These pistons and chambers are matched.
@@pacificmike9501 I've decided or been advised that the dual plugs don't really help for my Frankenstein combo. Later on im just going to get S&S slugs to match the chamber. Might as well get all the available performance.
