Wow, what a monster. Pretty sure I wouldn't change a thing with the way it sounded up top, it sounded perfect! When is saw fest, i drive by there twice a week most weeks.
I'd love to see you get the iron bore to a level of trust for vintage saws ,that you confidentially doing them for service! Ive got a pL7 Remington and some others that basically have no cylinders available. I appreciate your effort to get the machining down.
Absolutely amazing Dyno chart. Your saws peak hp is 12 k peaks 3,000 rpms higher than Briscos 10hp 660. Same hp but the band is nuts. And at 12 k it's still has 4.5 ft lbs of trq.
I don't recall but you may be able to look into it. Any Dyno pulls that peak that high in the power and without torq not falling off. Imagine piping that beast. 10 pin sprocket piped WOW!!
@@steppoffaith8426 lemme take care of backyard bull first 😂 How are those 585xp holding up ?- looks like they got the makings of a good fiddler from what I can see
@@fabzacres-blackcat run 2 or 3 tanks a day through them. Stoughtest saws I ever touched. Throw 10 pin sprocket 36 in bar an those saws see how they like it. Most stock 90 cc saws won't hardly pull a 10.
Good luck Joe! That looks great maybe bump the timing like 4-6 degrees and I bet you’d get like 10.75 hp and 6.75 torque give or take a bit. I’m down with the flu so I’m not making it to sawfest
As always content that shows a different level of work in the saw world. Thanks for sharing dyno Joe hopefully the builds pull hard at saw fest best of luck 👍🤘
I love iron sleeves in my bike motors and find them so reliable……as long as I WARM it up first. Nice job but I’m very interested in the sleeves for a cylinder…..hmmmm
I can get the highways to hold up after porting better than the meteors. The meteors are horrible about chipping the plating. I will not touch those or the titanickel. Its a crap shoot tho bc I ported a titanickel for my personal ms440 and its held up fine. I like OEM, new west or farmertec to port. The farmertec are super easy to port but they are definitely not a long lasting plating lol.
I put a Hyway on my clone 395. Aesthetically, it’s was WAY better than the stock one. I’m going to give it some run time and pull it off and take a look….
Interesting the issues around having the cast sleeves move . I wonder if you could pin them on the axis side at the bottom and grind them just shy of the running surface ? Anyway , love the builds . Can’t wait to see what some timing does to it
I don’t see why there would be any realistic problems with using the sleeve. After all, it’s not uncommon in 4 stroke circumstances to use sleeves in engine repair AND diesel engines quite often use them from the factory. You GO Joe!
@@dynojoemods2764you play with that variance well. I think I would have run that chipped cylinder as is with the expectation of destroying it. Go for broke haha
@@dynojoemods2764in theory the nikasil cylinder will wear better vs cast iron , have better heat transmitting properties and will allow tighter tolerances / more compression. In practice I don’t think you’ll notice f all of a difference! Providing this service is an excellent option for those with older saws or cylinders that are hard to find / NLA … nice to see good ol fashioned American 🇺🇸 ingenuity on display ! 👍
Why don't you take the cylinder to have chrome applied to the cylinder wall? Cast iron conducts heat less well! Chinese chainsaws run on chrome cylinders.
Nobody is currently plating and honing blind bore cylinders. And I need it for a race this coming weekend. Cast iron definitely has some downfalls. But chipping won't be one of them.
I myself think 🤔 🎉😊😊 1O 1/2 HP W a chainsaw is good I still it could do better ported and W a oversize carb what the max RPM let me know thank U 😊😊OMG 1O 23 2O23
Have you thought about coarse honing the sleeve, to within .001" then a fine hone, then a ultra fine hone . With 600-800+ grit, the bore should have a cross hatch , under the smooth feeling surface. Possibly look smooth almost polished, i have seen ppl use sand paper with kerosene or diesel.and a hand hone, just a few dozen passes with a drill at full speed, i saw Lake Speed jr. Talking about a similar modern ring pack require a hone with this type finish, freeing up HP. Id like to see someone build a tiny supercharger that will fit a saw, even at 1-3 psi it should gain power, atleast 8%-10% or so , maybe a 1/4" groove could be milled in tge flywheel and a 3/16" gear pressed on to spin a small screw type or roots type blower, even a rotary vane should produce some power, geting to 1 bar, 14-15psi is kikely impossible, the seals could possibly never handle it. However 5 -7psi or less i believe is possible, the seals may pop, i belive they can be managed. And it should double the TQ. Or near it, especially if a micro methanol injection can be incorporated a little 2oz bottle possibly using a venturi and boost pressure to spray water methanol into the engine at full throttle. It cools the intake charge and simulates high octane fuel. I believe that saw could do 20 hp plus,
Wow! 10.5 - 11 INCREDIBLE
The sleeved cylinder looks so darn cool with port work. Especially the finger ports
Thank you
Cool! Thanks for sharing!
Absolutely fascinating! I love watching passionate people doing what they love.
Thank you
Yeah buddy! Jo you are the man, aint no denying it, that whole process is very impressive
Thank you! I appreciate it!

Wow, thanks! I appreciate the support!!
I enjoyed the whole process. Thanks, Joe.
Good luck at Sawfest! Thanks for taking the time to show us your work. It’s always nice to see what you are working on.
That cylinder you did is a work of art. Hope you win, no one works harder than you.
Thank you
Outstanding!
Thank you
Absolutely loved the content! Thanks for sharing Joe!
Thank you Joe.!
You should refurbish old 394 cylinders. I want one!
Good luck at saw fest

Get well soon.
That was a fun video
This is one epic saw now! Good work Joe!
That’s a lot of work Joe! Whew!
I'm going out on a limb and thinking you will probably get better ring seal so the friction difference is a wash
Cool job joe🪵👍
Thank you!
Joe, that cylinder will last a long time of depending on what type of material your sleeve is. Awesome work. And good luck at saw fest.
Thanks 👍
It is actual spin cast cylinder sleeve blanks. It should be fine for a while

Gonna get my ass handed to me🤦🏻♂️🤣
Hey now... I still gotta make it to the wood...
Man i love this kind of stuff thanks Joe!!
Very interesting to see this type of machine work on chainsaws
Assemble piston and rings and cylinder dry "no oil" of corse oil wrist pin and bearings, You will get noticable better compression ! It"s true.
Love it

As a bolt on they are typically great, but any mods they are very chippy.
@@dynojoemods2764 Thanks Joe, good to know.

Awesome
Interesting the issues around having the cast sleeves move . I wonder if you could pin them on the axis side at the bottom and grind them just shy of the running surface ? Anyway , love the builds . Can’t wait to see what some timing does to it
Yes you can pin them. The problem gets to be not enough aluminum cylinder left to be able to hold them in tight away from the pinned area.
@@dynojoemods2764 yea I figured there would be plenty of limitations there . Interested to see how it ends up .
Nice video.
Nice fix! Were you using the same chrome face ring in the original chrome bore?
Yes chrome ring that was used in the nikasil bore. Chrome on chrome doesn't work well at all.
@@dynojoemods2764 That makes sense, I was thinking the original bore was chrome for some reason.
Have to say, this is the first sleeve I've ever seen in a saw- What is it made of? Cast iron? Thanks again for another fantastic video!
Yes cast iron.
I have never seen that honing process. Thanks for showing that. Is there grit on 2 opposing side or 4 sides?
1 stone and 2 other points of contact for a guide.
thank you for replying!@@dynojoemods2764
I don’t see why there would be any realistic problems with using the sleeve. After all, it’s not uncommon in 4 stroke circumstances to use sleeves in engine repair AND diesel engines quite often use them from the factory. You GO Joe!
Mostly has to do with me sizing it correctly. These saws seem to like different tolerance than say an air cooled mx cylinder.
@@dynojoemods2764you play with that variance well. I think I would have run that chipped cylinder as is with the expectation of destroying it. Go for broke haha

Of the aftermarket cylinders which ones do you find port the best? I’ll never touch the titanikle ones again for sure
The plain white box / farmertec. Just the cheap plain ones but the ports are pretty rough
That saw is an animal.
Hi can you tell me the type sleeves to use in high rpm 2 stroke

He aint wrong us chrome shut that program down awhile back. Thus this. Youll get it dialed im sure of that.

Would you build me a Husky 272 cylinder?
Build a 272 cylinder?
@@dynojoemods2764 How much would you charge me to build me a 272 cylinder.
A ported race cylinder. I can put it on the saw.
that honing machine doesn't look safe lol.
It has a clutch that slips with too much load.
