I really just enjoy your quiet and warm caring and charming attitude. Have a port out the front without a little pipe on the inside side it’s getting pushed from the middle of the cloud in the can… it’s not a pipe…. I watch your videos because you are working with the newer models and I don’t have or really see these saw’s… but I’m now really familiar with what they look like inside just incase one gets dropped in my lap….
John … don’t worry about the haters , you HAVE got a great Chanel & you built great saws ! I see a lot of good Guys (builders) getting very frustrated/ negative and it makes for shit viewing , loss of likes etc. Carry on & block those jack asses who’s only goal is to piss YOU off !
I'm right with ya on the dual port theory. I think the lung porting works great on a few other saws besides stihl. You make this sh!t look like a art form lol. Good job sir!
have you ever heard of a man named Curtis Sparks ? He built me a top end for a 250 R for the tulsa shootout. We didnt win but greg baker did, anyway a great man that was very hwlpful
73yo just discovered the idea porting saws. Used to do these things to my race bikes in 60's and 70's. I've used chain saws but never thought about this before and I am very curious. Don't know why or how I would use one, but I think I want one!
My stock 462 with the WCS kit, factory muffler port blocked off and just the bark box. Sounds better, snappier and more peak power I believe. Then with it dual setup.
Love your videos . I wonder if there is a lite wrist pin (or can you make one) To help with weight of moving mass. This would put it on a serious diet . Just a thought for a old outboard mechanic. Lit up old OMC s
First of all, the clean air is coming under the piston around that stuffer and after that the injector injects a portion of the fuel underneath the piston!
alright this is awesome to see. I did a build virtually identical to this on my 500i, (only difference is i tried a windowed piston) and it runs amazing.. except it keeps 4 stroking in any cuts that are relatively unloaded (limbing, scribing, plunge cuts) Whats even stranger is a did another one prior, but didn't touch the upper tranfers, and that one has no issues with 4 stroking.. its kinda driving me nuts. im seriously considering saying f*ck it and finger porting it just to see if i can fix it. any insights from anyone on here would be appreciated, lol
When you say shortcut the uppers do you mean finger port? I’m kinda new to porting and all the terminology. Also I did the windowed piston on my other 500i and it runs perfectly, completely solved the 4 stoking issue. And on that one I didn’t even touch the upper transfers.. I’m just trying to make sense of it.
My muffler has three holes in it. Runs cooler. Sounds kind of strange though in the mid range with no load on it. It doesn't have that four stroking bubble to it. Best I can describe it it sounds kind of like it's just free spinning. Strange. I've got another stock muffler to play with. Edit to add, I've seen several people show their cylinders on here but yours by far look the best.
30 videos is 30 days he says…. Posts 2 more and then none for 11 months after. This tracks with what the forums are saying about how this guy treated customers before totally dropping of the face of the earth 🤣
The reason people run dual port exhaust is because they think the noise is actually making more horsepower just because it's louder. But the fact is a lot of people don't understand how a two-stroke engine works. When it expels exhaust gases. It also gets rid of some good oxygen along with some unburned fuel. That's why expansion pipes on motocross bikes help with this problem. Believe it or not, sometimes a little bit of the wasted unburned fuel will go back in through the exhast and be burnt on the second cycle. But without the expansion chamber this cannot take place properly. So dual port just makes more noise and loses more air and fuel = horsepower loss

Hes a great builder
What happened to John?!?
No new videos in a year
I was super excited to see his video about dyno testing single port vs dual port mufflers
Thanks for your video’s John. Totally enjoy
great work buddy, i’m very much a novice builder but enjoy gaining some wisdom from the likes of yourself
have you ever heard of a man named Curtis Sparks ? He built me a top end for a 250 R for the tulsa shootout. We didnt win but greg baker did, anyway a great man that was very hwlpful
Awesome, just finished a dual port muffler.
😅
Anxiously waiting on the exhaust video.
Thanks
Still LOVE Every second John.. 👍

Super cool vids. Your extreme and thats awesome. I can tell you really like to do over the top work.
Make more videos. I have a 500i been using for 3 years and need it pimped

I’ve always thought the same thing about dual port mufflers I had just never heard anything bad about them before so I just assumed I was wrong
Cant wait for the Muffler Video.
Great Content as always.
Thanks John
Does wiesco make standard bore pistons for a sthil 066mag? Good explanation vid sir. Have a good weekend buddy.
Love the video!!! Where would i go to purchase one?
Good stuff john!!

Love your videos man.
Hola se puede recuperar el cromado del cilindro si se ralla?
I live around Oklahoma City I want 2 of my 500i's ported and up graded any suggestions?
What’s better ported or big bore? Or why not both?
haha I can hear a dog snoring in the background
That's strange those green filters are whats used on my wood splitter lol
First of all, the clean air is coming under the piston around that stuffer and after that the injector injects a portion of the fuel underneath the piston!
Do you work on echo
That would flow so much better without all that plastic support Material clogging up the middle of the intake…
pan to the snorer please 🤣😂🤣
alright this is awesome to see.
I did a build virtually identical to this on my 500i, (only difference is i tried a windowed piston) and it runs amazing.. except it keeps 4 stroking in any cuts that are relatively unloaded (limbing, scribing, plunge cuts)
Whats even stranger is a did another one prior, but didn't touch the upper tranfers, and that one has no issues with 4 stroking.. its kinda driving me nuts.
im seriously considering saying f*ck it and finger porting it just to see if i can fix it.
any insights from anyone on here would be appreciated, lol
I think a windowed Piston only makes sense, when you shortcut the Uppers.
do you sell your ported saws or no?
When you say shortcut the uppers do you mean finger port? I’m kinda new to porting and all the terminology.
Also I did the windowed piston on my other 500i and it runs perfectly, completely solved the 4 stoking issue. And on that one I didn’t even touch the upper transfers.. I’m just trying to make sense of it.
Not at the moment, Falling is my day job, I mostly build saws for myself.
I may start soon tho.
My muffler has three holes in it. Runs cooler. Sounds kind of strange though in the mid range with no load on it. It doesn't have that four stroking bubble to it. Best I can describe it it sounds kind of like it's just free spinning. Strange. I've got another stock muffler to play with.

My brother is Christ if you make a turbo for the 500i put my name on the first one I’m buyin it

I think John is out…😞
I honestly will never ever run a dual port muffler again. I lost quite a bit of power on my MS660
