That 7900 cylinder is capable of a WHOLE lot more than you’re giving it credit for!

Some compensate quality with quantity.If you use better metal you can have the same specs with thinner walls and lighter but equally strong result.Sometimes,less is more.

A OEM ported 7900 is a force to be reckoned with and takes a strong 660 to beat one.

I think your a madman!!! The wheels never stop turning my friend!! What a neat set up that will be .wow. be good!! Hello to all the other subscribers!!

Love the ingenuity Harvey hope it works. Keep lovin and being kind. 🌲❤🌲

It's so inspiring and exciting to watch all your educational videos. Bless you for sharing your wisdom with us!!!

I guess this guy finally got his saw back, in pieces. Yeah, dolmar top ends suck so bad they are head to head w 500I

I like where you're going with this. Can't wait to see it in action!

Just WOW! That thing will be a stud! Thanks for sharing!

This is the greatest entainment on YT. A mad scientist at work! Great stuff.

As Michael Keaton as Beetlejuice said "Let's turn up the juice and see what shakes loose".

I like it when you do the “what-ifs” ! Nice Ironhorse!

Love the thinking out of the box buddy. Will be a very interesting build to watch. Sure you make it a strong runner 💪

Innovation is important. I'm glad I just found your channel today. The reason i search KZread is because I found a gallon of Dolmar chain and bar oil yesterday, I was wondering if the oil is any good. Looking forward to seeing your upgrade and running dolmar chainsaw.

That Pretty Cool ,Mixing Two Manufacturer’s Parts Together ,Keep On Keepin On ,Great Job On Your Video’s !!!!

Excellent idea can't wait to see what you get, should be a torque monster. Thanks for sharing great channel great content.

Yeah those are really good saws. Was great watching you learn and figure things out. I hope it worked out for you.

That is one of the coolest things you have done yet stay true my brother

Bump….Harvey, what ever happened with this. If it’s on KZread I can’t find it.

I put my cylinder on facing the wrong way and my saw runs better now.

Love this just messing around and building Legos for adults I love this video Harvey

That's good stuff harv. Love that feeling when yer onto something and hrs go by like minutes! At least the tunes in that other video were good ones

Ironhorse hybrid ! This is it baby ... what if’s can turn into a powerful Saw ! Sometimes little things , make BIG differences !

Now were building some saws love this content taking things that don't belong together and making it work that's hot rodding 👍👍can u open the hole up on the case's to help with rotation get it close to the counter weight on the crank if there's room get bell hopper to trim the base if you dont have access to lath or mill 😁

this is what i love seeing , just like playing with lego blocks right

Keep at it. Can't wait to hear it run.

Awesome job can't wait to see it run

The Trees Will Be Shaking To Their Roots...LOL!!! 🌲🌲🌳🌳

Gonna be a crazy build! Fun to watch!

Is it an Dolmar? Is it a Stihl? It is an IRONHOSE !!!! 🐴🌳😎

My supper was a good one too. Thats key to it all. Like where yer goin with this Dolmar!

Looks like it's going to work Harvey that's why your the best appreciate ya

Keep going! Its gonna rock! :)

Well I see two things to keep in mind Harv. Some of those big bores don't idle too well if you get too far on the intake timing, and the base flange is as thick as it is for strength. But I like a challenge too so lets see it pop!!

Definitely would like to see it run

the smirk on your face at the very beginning said it all

HARVEY I AM BEHIND YOU 100% I guarantee YOULL HAVE THAT SAW PURRIN LIKE A KITTEN ,TILL YOU PIN THE THROTTLE AND ALL HELL BREAKS LOOSE ,LOOKS LIKE A COOL PROJECT GOOD LUCK TO YOU BUDDY

I’ll give ita name. Frankenstein😆👍. Watch reciprocating weight on that. Keep your eye on the bottom of that magnesium crankcase after running it hard. I had one oversized that developed major failure across the underside. Good luck Harvey. Anxious to see it run. Gene

Hello Dr. Ironhorse I see the stable got a tune-up lookin good brother I hope you get some sleep.

Wow, you know when someone is able to mix and match parts and make it work they are masters at there game! Some Uber lever chainsaw black magic going on here. Hope it like a cummins diesel!

of all the tools I own, my chainsaws are the most dangerous, require the most maintenance, do the most work in a hurry, and are the ones I most enjoy using. being from Illinois I hike up to Wisconsin to get my ethanol free fuel. drain my saws" gas tanks and run em dry after every use. they always start and run great. my Husqvarna 372xpw (circa 1970) is one gorgeous saw. picked it up from the Chainsawguy 6 years ago. regretably the man retired, hope he's healthy and having fun.

FRANKENSAW it's ALIVE !

Hhaha! Your a wild man Harvey!

Have you ever checked out John Riley's channel? He may have already done that.

Iron horse is makin a 9010 out of a 7900, sweet Jesus!

It is gonna work and it is gonna RIP!!!! I cant wait to see this!

That is going to be a tork monster. 😊 at least It should be. 😊😊👍👍👍👍

I can't wait to see it run !

MAD science .love it

i'm in for this one. maybe u could do the same for my husqvarna 120 mark ll homeowner saw lololololo

cant wait for more !! thx

your a smart guy harv lovit

Wicked weasel you make it happen mate hahaha yeah uncle Harvey that's going to be phat with a ph nice idea

Interesting. Will be waiting to see How it turns out.

I love this sorta stuff I really do .. it will work U know it will.. dose it have the same stroke .if it doesn't is that why you haft to machine the bottom down so the piston reaches the top .. hahaha can't wait

aww man good lord that will be a monster

Hey man what ever happened with this bad boy?!

Case capacity an issue? Fun to play :).

Buckin sent me over. How are ya.

You know yer stuff.

Harvey you will get it that will be a fine saw from NC Ed

You need a Smitty 3 in 1 mill lathe buddy , easy to run and you could shave that down np. Your in master level now, look forward to seeing you solve it.

Yep! 066 mag big bore with a dome Piston!

Did this ever happen? I’d say it was too much work for what it’s worth. I’d just slap a bb kit on it and be happy with 84cc.

Cool..

Iron horse I’m looking for a flywheel for my 7900 I just snapped the key way

you act like you know more than the engineers at dolmar, stihl and husky. that is one hell of a knee slapper right there. if i injure my knee because of you, i will bring a lawsuit against you! LOL

How do I get ahold of you ironhorse

d hamby yeppers and that’s HIS CHOICE ! I’ll exercise MINE thank you very much 😁 ... remember ... I OWN 2 saws he built for me years ago - a 241c insane-o and a 461R “early version” insane-o ... I put a little “hot-sauce” of me own into both of em ! And went from “zipped” to zippy-er ... just put out a video of me hotwoods 441cm (70.7cc) vs the 461R (76.5cc) and am right there (5%) whilst giving up almost 8% displacement ... me hotwoods with tuned intake took his 241c insane-os’ lunch money (no tuned intake ) by a considerable margin ... you pay 2x the price with Hotsaws101 ... you ain’t gettin 2x the Saw by no means ... and that’s the fact ...Jack ... tape don’t lie pal kzread.info/dash/bejne/qHqMtcyedKeyqJs.html

Never change height of ports... Changes timing and flow design. Width can be opened. Did racing dirt bike engine s for decades .
