First fire and cuts on the big bore 500i. Throw in some dyno runs testing different muffler outlets. For porting or product info visit the website. worksaws.com
This is awesome. Good plan with the sleeve, can't say anything negative about it, I use Stihl rings when I rebuild TriZingers with big bore kits, never had an issue
This one intimidated me a bit, less band cut than normal and a touch higher exhaust port. But dropping the cylinder a touch more may be in the future. Curious how the ring will seat in.
Your sleeve work is looking real nice! It is a real bummer about the plating. Looking forward to feedback on this build. Hopefully you can come up with a plater to work with. I suspect you will be able to do a fair amount of these big bores. Thanks for sharing!
Hello, I believe I saw a video where a person built the 500i using a 661 top end. Do you know anything about this? Any updates on how the sleeve is doing now that it has some tanks ran through it? Thank you.
I know this a year old or older but I’m curious if you did a relearn after doing the big bore and a relearn after each muffler install. If you didn’t you left a lot on the table. Just curious that’s all
Those adapters definitely report way low. I'd say 50psi or even more on that size cylinder. My 462 feels stiffer to pull over than my 461. I get 190 on my 461 without any adapter, and the 462 shows 130 with the adapter.
@@dynojoemods2764 well cast iron it is then ! I know I saw a video of a guy plating in his garage but it wasn’t a blind bore cylinder. Even if possible to do a blind bore idk if I’d want all those chemical baths laying around in the shop 😂
I'm guessing I've missed some prior videos to this build, gonna go back and look them up. My question at the moment is how does the fuel injection compensate for the bigger bore? Did you have to tune it with an electronic tuner or ???
@@dynojoemods2764 I did email you about upgrading my 500i last year and I will be in line for the plated sleeve option. Keep me posted and keep up the great, informative videos.
That's a fantastic build Joe.. Just a question from a dummy.. Is it possible to have a c&c machine cut out the ports for the sleeve? I'm not suggesting that it would make a difference or that you should go out and spend stupid money on one.. My question would be if it would make things easier or even work with the sleeve? Love all the builds brother and am a loyal subscriber who is just curious.. All the best to you
Thank you. Yes you could fully cut the ports. Most of these being 1st attempts, I wanted to leave the sleeve and be able to set the ports where ever. If I ever did multiples, I would make a map and open the holes in the sleeve to 80% or so. Doing that, you have to be very careful not to mess up during install
@@dynojoemods2764 hey man, I really appreciate the response. Just wanted to tell you that I'm so impressed with where you fit in this community. All of the builder's / porters watch how you push the envelop. We all admire the courage it takes to do shit that no one else does. I completely understand the theory of porting the sleeve with reference through the holes drilled. Absolutely no one that I have seen has ever sleeved cylinders because you can't find anyone to chrome them for you. Please have a look in Canada if you haven't already done so, we have some great shops especially in western Canada. Anyway, I'm really curious to see how this 500I does in the real world of logging. Keep putting up the great content Joe, we all appreciate the effort more than you know. Cheers brother
@@dynojoemods2764 If you had enough axis on a CNC machine, including one of those rotational mounts you could probably build mounting plates with tight studs for indexing the cylinder. Id say you could get the cnc to do MOST of the work, reducing the need to even pre drill. Maybe even for rough porting. Then you are just going in for cleanup. Problem would be machine cost and programming time.
Sweet build. What about plating the sleeve? Wouldn't that give you the best of both, not a blind bore to get plated, but you'd have the plated bore 😉. Same deal up here when I checked, hey don't do blind bores.
@@dynojoemods2764 no way! That's nutty. Seems like everyone is pulling the pin on doing that eh. Over seas stuff I guess isn't making it viable to try and fix shit now adays or something?
@@victoriousvictor7978 Yeh, it is rather frusturating lol. I would guess blind cylinder to be a very very small percentage of the work. I just may have to learn how to do them myself.
@@dynojoemods2764 I’m in bay city , I gota find the time to come down one day , I got a 345 husky n a 026 id like to have you look at , I got a 372 also but you said ya dont work on clones , didn’t know your were in MI till other day
Exhaust ports behave like loudspeaker vents : smaller surface leads to higher air speed thus saturate at a moment. Could you give us the exhaust port surface ratio in respect to cylinder exhaust surface ?
This is a bit different than most. Area at the cylinder wall is a bit larger than area at the muffler flange. And muffler outlet area with the dual pipes is much larger than both.
@@cyrillepinton3398 Mostly because of the larger bore and piston skirt. They allowed me to go much wider than stock. And stock has a relatively small exhaust flange too. So this is wide, small, wide again.
@@dynojoemods2764 interesting. I would have not gone so far for two reasons: it's against the theory of two strokes tuned exhaust (conservative argument), and it leads to higher exhaust acoustic impedance for the cylinder (mechanic would say it accelerate the exhaust gaz speed at the output: more resistance). Could it be the reason of shorten power band at high rpm in regards to standard ported 500i?
@@cyrillepinton3398 The shorten powerband on the graph is the 500i "tune" they go rich as soon as it sensed any load. 98% of the time the 500i will give me that dip.
@Dyno Joe Mods cheers. Guessing after this cutting season 2 of mine will be pretty tired and need some new life put back into them. No luck finding someone to plate them yet?
YO JOE! HOW MUCH YOU ASKIN TO BUILD A SAW. this fella trims for a living. And stuff happens. They get broke. I want a built 661. Have two need one built. HOW MUCH?
I've built a few 660'S . don't go to crazy in the horse power numbers otherwise you will snap the crank. ( I've done this before ) . a 101 cc big bore putting out 10.7 horsepower runs sweet and you can still work it all day.
You’re on a whole different level brother.. seriously this is incredible stuff.
Thank you.
i’d agree with this comment
@@dynojoemods2764 have you tried Millennium for plating? BTW nice build.
Dyno Joe, what you do to these saws is impressive. Always very very interesting. And your work is nice and clean too. Great stuff
Thank you.

Joe great work as usual, I like the incremental changes that are now observable because of all the work you've done. Bravo! my friend Bravo.
Thank you
joe this is fantastic
Badass brother!!! Love all your videos, keep up the awesome work!
Cool build great vid I hope you can get a plater all lined up
Nice bit of exhaust back pressure on that muffler I'd expect. Nice clean design.
Thats a nice build I like the way it sounds Seems really responsive Cuts nice
Man when it comes to official fabricobbleing you are the man top notch
Thank you. I try and get it together lol
Excellent video Joe! A lot if work on this project with great gains and info.
Thank you! Yes, they take a bit to get put together.
U r definitely a effin chainsaw motor ninja bro phenomenal work
👍🔥👍 Dang it Joe ! Now I want a big bore ported 500i .
Damn that saw turned out awesome! Amazing work joe and helper😉
Thank you! He sure is catching on fast.
@@dynojoemods2764 fa sho bro! 😉
That’s amazing work!
The future of ported saws, get your sleeve on!
Lotsa work. Nicely done.
Amazing work sir absolutely love it sir have a good week.
Thank you
May take a bit longer for that chrome ring to seat in as well. But boy when it does, that thing is gonna really wake up! Excellent work.
This one intimidated me a bit, less band cut than normal and a touch higher exhaust port. But dropping the cylinder a touch more may be in the future. Curious how the ring will seat in.
Thank you Joe love your videos!! I will not buy any fuel injected saw period!!! Thank s again!!!
Great channel mate 👍
NICE WORK!!
Your a freaking mad scientist man !
Lol thank you
That saw is great!!
The John Lennon muffler is Ace 👍
Think those are great numbers. Almost my standard go to.
That’s a lot of work joe! 😅 I bet that iron is considerably harder to grind. Great power!
Your sleeve work is looking real nice! It is a real bummer about the plating. Looking forward to feedback on this build. Hopefully you can come up with a plater to work with. I suspect you will be able to do a fair amount of these big bores. Thanks for sharing!
Glad to see the injection is keeping up. I like the additional tests you did with the different muffler covers on this build.
Thank you!
I am very curious the longevity of this build. It is going to get ran hard. So hopefully something is left to come back once he is done.
Wow that sounds great and that throttle response! 😀
Man good job I would love to do this to my 500i cut a lot of hardwoods logging and very interested in this style of a build thanks
Thank you, that is what the owners cuts out in the Midwest. Lots of hard wood. He will be running the snot out of it for Sure
Keep us updated on the longevity part. What you are going is just fascinating.
Millennium Technologies is our local go-to for plating.
They stopped doing blind bores
Monster comes alive.😮
Imcredible
Congratulations, great work... success!In terms of durability and resistance, how is it?I wanted to do this with a stihl 661!
Be interesting to see how the saw doe's
Hello, I believe I saw a video where a person built the 500i using a 661 top end. Do you know anything about this? Any updates on how the sleeve is doing now that it has some tanks ran through it? Thank you.
Try Millennium Technologies for plating
Your hmwf run on this chart is that the stock air filter and your usual style of muffler mod?
I know this a year old or older but I’m curious if you did a relearn after doing the big bore and a relearn after each muffler install. If you didn’t you left a lot on the table. Just curious that’s all

I agree, that small of a combustion chamber, the psi will be off significantly. Mod the adapter with a valve.
I like the sleeve. I understand heating the cylinder, but why did you not freeze the sleeve?
Heating adds enough clearance. Also the frozen sleeve steams up and makes it difficult to see.
👍 … US chrome is the only place I know of that will do blind bores but their prices are cost prohibitive
They stopped doing blinds
@@dynojoemods2764 well cast iron it is then ! I know I saw a video of a guy plating in his garage but it wasn’t a blind bore cylinder. Even if possible to do a blind bore idk if I’d want all those chemical baths laying around in the shop 😂
Did you try melenium technology they plate cylinders
Bro, which stroke 500i ?
Do you do a base gasket delete on 500i ?
Great work!!
Gasket delete and machine work
About 20, 25psi was my SWAG
I froze my sleeve and heated the cylinder... I had a SNUG fit on a 461 cylinder. I've been slacking... I still have to bore and hone... lol
That works too. Can't wait to see your project finished up
I'm guessing I've missed some prior videos to this build, gonna go back and look them up. My question at the moment is how does the fuel injection compensate for the bigger bore? Did you have to tune it with an electronic tuner or ???
It fuels fine on the high side. Has some low end problems, but waiting to see if a dealer reset clears those up.
@@dynojoemods2764 That would be interesting to see how it works out.
@@PurpleNovember
I have just learned that. Working on getting the scan tool to be able to check and recalibrate these
what horse power is this saw
I bought mine new, sold it after four tanks of gas. Sawed great, but set it down then come back minutes later and the saw wouldn't start.
When is the update coming out?
Stock 500i has no revs, peak falling off at what 9250rpm? The way that stretches out once ported though is impressive
💪😁👍
In the long run which will have a greater longevity, the steel insert or a plated bore assuming you can get it plated? Plated
Plated will last longer, and produce more power.
How much? Not sure. Prolly 3-5% more power and 10-15% longer bore life.

@@mattfleming86
It isn't a big deal to open them on the manual, but line up while dropping the sleeve in has to be that much better.
Why would the adapter show lower compression? Isnt compressed air, compressed air?
Sometimes the extra volume before the valve throws the reading off
How’s the Chinese knock off on the Milwaukee battery’s? I was always curious. Huge price difference. Love the vids thanks.
When they work, seems to be on par. But I bougt a pair. And one was junk in 3 weeks. Other is going fine.
Sweet build.
What about plating the sleeve? Wouldn't that give you the best of both, not a blind bore to get plated, but you'd have the plated bore 😉.
Same deal up here when I checked, hey don't do blind bores.
What about playing with aluminum sleeves if possible. An open aluminium sleeve would be easier to chrome.
You couldn't get a chromed sleeve pressed into the cylinder without cracking the plating. Needs to be installed then plated
Sad they won't plate blind bores.
💯💯💯👍👍👍🤝🤝🤝
Why did it have plating issues in the first place?
The cylinder came from a damaged saw to begin with. Air leak/straight gas.
I've been looking for a company to plate a blind bore... nobody wants to touch it with a 10' pole. Lol
Yeh, supposed to be one place tooling up to plate, but nothing yet
Have you tried mongoose engineering in vancover Canada for the plating?
Will have to look into them. Thank you!
