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.
"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.
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...
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
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
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
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.
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
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
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.
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!
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
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 .......................................
That one is finished and in our list of videos. Go to our RUclips 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.
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.
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.
Fuel atomization is the word you were searching for. The texturing causes micro vortexes that causes turbulence in the intake air, causing better fuel atomization, resulting in a better A/F mix. But we knew what you were saying.
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.
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.

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.
Circling back around to look at those beautiful parts. Lovely.
You bet. Couldn't happen to a better guy.

Yah, we're getting there. Priorities, life, you know. But it will all happen. Thank You.
Heads look amazing,Real nice work Mike
I didn't do them. But I love 'em.
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!
Love me some high performance evo tech talk
We'll be putting it together in a few weeks.
@@pacificmike9501 can you believe I finally upgraded to an evo last year. I'm only 42 years old... I've been riding my Shovelhead since I was 12 lol 😋
That was smokin hot mike that motor is gonna hum nice job
Yah.
I’m over here drooling.
Me too. My buddy's gonna love 'em.
Another excellent video Mike . Thanks
Glad you enjoyed it
That evo build is going to be sweet.

Great show today. The only order is disorder
Thank You. You have a point.
Mike, those are some beautiful pieces of metal. Beautiful finish and polish, a real piece of art.
Yes, some really nice work.
Looking good Mike !
I didn't do it. And, it's not for me. But I love it.
Beautiful port and polish work!
That's from Dave Mackie Engineering. That is the "Megasphere" design. Reshaped chamber and custom pistons.
I'm acquiring my old evo fxr back in a few weeks. I'll be interested in this evo build. Great work Mike!
Thank You. We've already rebuilt an Evo on the channel. This will be a high performance top end to a stroker lower end. Should be fun.
A friend had similar head work done on an 88" Shovel. It was amazing!!!!!!
I'm sure it was.
You stay healthy Mike....we need to hear that engine fire...!!!!!....stay safe bro...:)
Thank You. And you too.
Great work Mike!
Glad you enjoyed it
Very nice work on the top end👍🇸🇪 Kjell "the swede"
Thank you very much! I had it done by guys who do that.
It would be nice to hear/see when you start it up 👍🇸🇪
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.

Hi Mike, what is the displacement of that engine with the stroker crank? Great videos beautiful parts.
I believe it is 89 cu. in. Thank You.
Fuel atomization is the word you were searching for. The texturing causes micro vortexes that causes turbulence in the intake air, causing better fuel atomization, resulting in a better A/F mix.

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.
