excellent Gordy ! I've been a motorcycle race engine builder for 50 years. I'm old. after building hotrod Harleys for a few years, I went on to tune race Kart engines, to me the ultimate in 2-stroke tuning. learned a lot. ported a lot. ruined some cylinders. your craft is making better use of tuning than my race motor work. way to go Brother.
Just got myself a Holtzfforma 880 clone kit saw, this is exactly the info I'm looking for to clean up the ports prior to final assembly on it. Hopefully will make a good difference right away as the casting looks pretty average on first inspection. Thanks for sharing the knowledge Gordy
Absolutely fantastic sage wisdom presented here! Pay attention here people! I’ve been in the performance automotive, motorcycle engine building arena for decades. He is giving you all of the secret information here for building performance from any engine. Thank you for sharing your knowledge here!
Great explanation. I love exchanging port timing numbers with my buddies and learning what works for some and doesn’t for others. Then you find the common denominator of the what and why’s. That’s really a good way to learn too if you’re starting out find guys on your level or close to and share your ideas.
We have snow here, made my log job muddy so I finally can have a day in the shop. A little = alot in porting. Get comfortable and take your time. I recently replaced the intake and exhaust gasket in a Jeep 4.0 I built and ported 20 years ago. It was really nice to be able to see the fruits of my labor again after all these years and 438,000 miles of reliability. The time spent on your builds will give you a higher level of confidence in yourself and your equipment. One will make mistakes but keep going, one day you will look back and be glad you did.
Very nice! It’s really funny but as a young dude going into high school I absolutely hated working on cars because I had to work weekends in my uncles junk yard… about 12-13 I started working on some of the stuff setting around because when my uncle would take off for his afternoon bar run we would jump into whichever whip I had got going and play dirt track racer in and out the gravel back roads that lead you back into the property! LMFFAO! About 14 I was talking with my other uncle about rebuilding an engine and had gotten some good basic information… so we set about on a ford fairmont wagon and it was a pretty decent 5.0 cruiser for our first official builder… my uncle Jonny helped me some with the getting my heads done by a buddy with a machine shop and whatnot… it ran a long time too! Mom drove it… we added a nitrous shot my junior year of high school but it only lasted for a couple months and then mom made me take it off… some teenagers were joyriding and she wanted to put them in their place as the wagon never made it past the multi colored primer stage and she scared the Holy Heck out of herself!!! A couple cuss words were uttered for probably like the 5 time in her entire life and I was in the driveway making sure she didn’t kill herself on the button… still wish I could have whiteness exactly what happened!!! My 3 year older sister said… we went really fast!!! 😂😂😂. Porting saw’s is awesome… people get all defensive about talking numbers and whatnot like they might loose some work over it? If you have a great reputation you’ll never loose anything to another shop! There’s a stream of guy’s who are getting into saw’s just for fun and the porting work is going to just continue to grow the more and more people get interested and involved… if the guy could do it himself he probably already would have… there’s just lots of guy’s who are trying to collect the information enough to know what they are talking about… it’s definitely not the space shuttle it’s a freakin 2 stroke chainsaw engine!
I really like your stuff I bought a 660 that had the muffler cover and spikes on it!!! Didn’t realize the whole weight of your duel port muffler front covers from that really fantastic thick hunk of metal!!! Not gonna bend that up!!! Very nice 👍 😁
Gordy, Sir i got a question... I want to get the most power I possibly can get from my Stihl MS362 can u offer any advice? I'm in Pierce County Puyallup Washington... I believe you're local to me... If you can help me figure out what I can do for the best result I'd be really grateful...
Hey brother. Your spot on as far as my knowledge. I mean spot on. . Nice work bro. .. didnt know how digital even a gasket thickness makes on these little screamers . Not to often i run across a common sence mechanic and you have the goods . All and anyone who wants to learn something , needs to pay attention to you and your knowledge . Thanks man good to know there is others like myself that get after it and actually know what there talking about. Hey bro i eat sleep and thrive on these air pumps so i can pick up what your laying down . There very touchy and it has to be perfect or they wont run good or at all. 10 thumbs up to ya , pay attention people this man knows what hes sharing with you . 100 percent. . Thanks man appriciate you .
One thing for new guys is buy yourself a $30 dollar digital caliper for measuring the thousandths. Figure out how many thousandths = one degree and take off only about one to two degrees at a time. A little goes a LONG way. When I port most of my time is spent in the transfers making them more aerodynamic. Great stuff Gordy, thank you.
I don’t have a reason that I can put my finger on, but I’ve become addicted to your products and videos. You are quite a wonderful person and I thank you for sharing your business and knowledge with myself and surly others.
I was thinking of giving a compliment like yours myself. I think as guys we get tied up in our self pride and just can't tell a guy man you nailed it. I want more to leave the constraints of the nine to five more than anything. And not only has Gordy left the nine to five but he has the property that almost all of us would die for. Truly a celebration on the American spirit, capitalism and the desire to go forward. Awesome.
Just think. You have been working on small engines for 50 years, ported probably thousands of saws, and you spend your free time watching saw porting videos on TH-cam. You the man, Donny Walker, you the man.
Really good explanation on atomization . I used to port and learned these concepts back in the late 70's early 80's . You sure can make a lot of difference from where you place rough and smooth surfaces in naturally aspirated engines . Not so much in force fed power though . Good video . :)
this made sense to me because I watched a guy do the same for air flow on a muscle car and hearing some old experts from the muscle car era talk about air flow. It's about keeping the motor cool. I think the best way to relate the heat in a motor is for anyone who has over heated their brakes in a big truck; you lose your brakes. The same goes with the power in a motor! when it gets too hot, it loses power! the cooler you can run a motor, the more efficient it will be for long days of cutting! this was an excellent how to on increasing air flow without causing problems with the piston rings hanging on the edges. That part, I think was one of the top pointers on guidelines for shaping the ports for optimum air flow! Thanks, Gordy! Great video!
Ever watch NHRA drag racing? You know why some guys play games at the starting line? Because the hotter their motors get the more power they build and then the other guy blows the tires off. And those guys run solid blocks. No coolant
I feel like you are trying to say the original comment is wrong. Dont forget the "whys" of the alc burning nhra guys. There simply isnt enough time for the thermal transfer to take place in regards to running coolant. There are many other reasons for that one instance, but bottom line is heat=energy. It doesn't matter if we are talking photons, electrons, etc. Heat is wasted energy @Mr_Clean
@@Mr_Clean there’s a line on how hot is good and when it passes that threshold it loses power! The principle can be seen in breaks overheating and losing the ability to stop the vehicle. I’m no expert but there is a balance to be attained; and air flow is key to anything, including to ignition of sparks that drive the force in the engine! Without air, no fire, so air is necessary for ignition and cooling, and engine experts played with this a lot back in the 60’s through the 80’s especially when muscle cars were a big deal!
Great video! Honda discovered years ago that the intake charge mix and speed, over more volume made the most power. Polish exhaust, rough intake, and if possible increase intake charge speed by modification of venturi effect and distance to intake at the cylinder.
I love it Gordy!! Good video and great information for those of us at the beginner level. I would love for you to talk a bit about the stratified design and how that may differ for porting purposes compared to the non-stratified cylinders. I don't think I have seen a video on that from anyone yet. Keep up the awesome work and content!!!
You want asperation on the intake , picture the air and fuel across the ruff surface. It causes a turbulent mix. The exauhst is smoooth to get rid of it efficiently. I leaernned this 25 years ago with a two stroke racing quad. thank you Curtis Sparks
Yeah want that A/F in with velocity, dimple porting, whereas exhaust > smooth. Unburnt stuff hangs on to everything, even pistons, so, smooth & polished exhaust, don't give carbon deposits anywhere to hang on.
The easier it breathes, the better. Yes you can take it too far, but these saws now are so restricted that anything is an improvement. If you want dependability, open it up. If you want a race saw, well, that can get expensive. They can run really well for a short time, but after that goodbye. Nitrous will make them run like a scalded dog but anything weak in there will let you know. Compression can help a great deal, but once again if you have too much pressure something will give way. Great video. Bottom line, make em breathe easy.
Thanks for this info. It makes a lot sense to me. It's about air flo and atomization for best combustion. The timing issues makes me think I might want to let those with more experience work on saws I need for work. I have a couple I might be willing to chance experimenting with.
Great 👍 video Gordy very well demonstrated nice clean work. Good see your using OEM cylinder’s I found timing numbers pretty spot on in comparison to After market junk. Keep up the good work love your videos
Look there Gordy the grandson of two stroke commending you you know you’ve arrived I live on the east coast t and you two are the 2 stroke gurus from sea to sea be safe great videos
Thank you dude,that's about everything I needed to know to start messing with porting my saws that no body on TH-cam likes to show you.i already got the foredom I use to carve wood too.good job my friend and a big ol what's up.names Dan from Des Moines iowa.thankyou again
You need to watch iron horse if you haven’t already discovered that guy , he is probably the best at explaining things, for me anyway , him and Donny walker
In your opinion can all saws benefit from porting no matter the size? I have a Stihl 193T and 026. Both run well, but I've been thinking about porting my 193 to get the most out of it. However, I don't know if the improvements will be worth the time & money it will take to port, but I have all the tools and I'm always looking for another project.
I’m not brave enough to port and polish on my own fortunately I have Daves Sawshop in St Mary’s PA they built my 460’s for 300 per saw port polish muffler mod and tune saw its gone less then a week.
Great info, Gordy! Hey, I'm looking to have some port work done on a brand new 500i. I am here in eastern WA. Do you have any recommendations on someoneto use? I'd sure love to have you do it if your willing. Thanks!
Yep, keep it simple for us old guys. The info is good & makes me want to pull something apart. But ill wait till spring. Be cutting fire wood till January. Then northern MI. gets too cold. Thanks I'll be back.
I used to build and race F2 and F 3 Grand Prix 2 strokes. Primarily the TZ250 and the RS125. My question to you is, do you ever CC the heads or stuff the cases?
Hey YO ! Would you guys port my 500i ? Basically already ordered dogs , air filter kit and suspension kit from you guys, now I just need that engine work 💪🏻💪🏻
Well said Gordy. A little machine work and a little grinding goes a long way. I think we've all hogged a cylinder out and went backwards as we were learning. That Jacobs 261 on the bench?
Thank you Richard that is Jacob’s 261 he wants to put the OEM 261 muffler back on it John had put a 026 muffler on it with pipes and it’s coming loose so we are going to swap Also just gave you a follow and started watching your videos lots of great info 👌
Very good points in this, we all have our differences in work saws and how extreme you can push it but not over grinding a cylinder rod the biggest thing.
Stock 455 rancher here used to firewood duty. Would it be worth the time and effort to simply smooth out the porting and chamfer edges? Not looking for anything crazy just a lil more power
Have questions what do you think on blow down this 70 cc and bigger saw A long blow down made more. hp. Or short blow down make more hp. And the way I look at short blow 18 deg or less
@@westcoastsaw1368 no need to be sorry man, Im sure you are busy enough. The bark box alone did wonders for that saw. Your products are great, keep up the good work.
@@kylebakker7017 I can point you in the right direction if you’re looking for a reputable builder. I use Kevin LaVanway you can look up his channel. He schedules a month out but can build whatever you need for whatever you are cutting. Excellent standup guy. He’s done 7/8 saws for me.
I'm thinking about having my 441 ported. Could you give me any advice as to how I can find someone that does a good job with porting? My thoughts were to call some tree companies and ask around.🤷♂️
Exh. Port having arched top and bottom even out the contact pressure on the ring against the cylinder. Straight top/bottom puts all the contact pressure on the outside edges of the port which will wear out that position of the ring/s. Also there is less chance of catching the edges of the ring/s as they move past the port opening.
Talking technically the intake should be lightly rough in order to create a very thin strate of the air coming through that is in turbulent flow. That VERY thin film of turbulent flow is gonna like insulate the rest of the airflow from the intake walls, keeping it as a laminar flow that is the one you want to get for the maximum airflow possible.
Wish I would’ve seen this video a month ago 😢 found some other channels and it was just as simple as grind and polish according to them now I got useless saw. My fault for not researching more.
Gday Gordy, that was an excellent enaligy of the intake port and the bottom of the boat, it made me think of a flat bottomed car stuck in mud you can nearly pull it in half trying to free it if theres total surface suction.
@WestcoastSaw where can I get a degree wheel and what else would I need to start porting my own saws and would you be able to help me out with information on how to do it

Nice. Transfer work?
Another way to think of intake texture would be a golf ball. The dimples help the ball fly. Beware, saw porting is very addictive!
What about spark plug timing to intake. Does it matter?

Very good points in this, we all have our differences in work saws and how extreme you can push it but not over grinding a cylinder rod the biggest thing.
Great tutorial on porting. Much thanks
Question: what do you guys use to deck a chainsaw head? I’ve done some porting and have the tools for that looking at lowering heads.

That wilton bullet vise is a beauty.
15:35ish mark. To further help explain this, it's like a smooth ball travelling through the air and why golf balls have dimples.

Excellent video.. Very well explained
Hey Gordy Have you ever dimpled an intake like a goofball?
Awesome video. Might have to pick up a cylinder and give it a try
If ripping is good for intake why polish smooth exhaust???
2 to 4 degrees seems to be good working numbers!
Hey Gordy, do you do porting for the public? I run a Stihl 461 and its a great saw, but a little more go fast is always nice.

@@JS-oy6nn I agree, XS saws are runners for sure.
Smashing that like button!! Your awesome 👌
You also need a dynamometer or "dyno". Customers want to see the power before and after the "porting".
I'm thinking about having my 441 ported. Could you give me any advice as to how I can find someone that does a good job with porting?
My thoughts were to call some tree companies and ask around.🤷♂️
I saw one done by Mastermind work saws years ago, but don't know if he is still in business.
Why is your shop cold enough that you must wear a toboggan and heavy shirt? Does the colder shop temperature help with the porting"
Great video Gordy. A sheet of paper is .003”
I have a 362 and a 462 I've been running the Stihl fuel additive but noticed your fuel is blue what do you use
Amsoil saber
Awesome video!
Thanks Joe
Have you ever used the little buffing wheels an compounds to polish to a fine mirror?
that actually slows velocity.
Is there there any way I can get you to work on my 066 or someone that you will recommend for work like yours?
Have you ported an 881 mag yet? And could I ship to you guys a saw to port for me?
Great shizz mirokee..thanks kp up the gd work
port intake same as the golf ball....wander why that ball go so far?exactly try it
That's some nice grinding😎
Finger ports and blowdown, that’s the touchy subject
Can you do a smaller saw like an ms291 with a 20" bar?
That’s a clam shell motor. Very limited to what you can do to them.
Great Content Keep It Coming!
Exh. Port having arched top and bottom even out the contact pressure on the ring against the cylinder. Straight top/bottom puts all the contact pressure on the outside edges of the port which will wear out that position of the ring/s. Also there is less chance of catching the edges of the ring/s as they move past the port opening.
You got it. Thats what the man gordy said. Listen up now. Good job
Great stuff, might save me some money Lol.
Would you go up on the exhaust port if you do a base gasket delete?
Yes
Yes.
Talking technically the intake should be lightly rough in order to create a very thin strate of the air coming through that is in turbulent flow. That VERY thin film of turbulent flow is gonna like insulate the rest of the airflow from the intake walls, keeping it as a laminar flow that is the one you want to get for the maximum airflow possible.
Thats what gordy said. .....Just not that digital same same .....
Wish I would’ve seen this video a month ago 😢 found some other channels and it was just as simple as grind and polish according to them now I got useless saw. My fault for not researching more.
Like the '79 2tone ford
77 its mine now 🥰
Gday Gordy, that was an excellent enaligy of the intake port and the bottom of the boat, it made me think of a flat bottomed car stuck in mud you can nearly pull it in half trying to free it if theres total surface suction.
Heck yeah dude thanks for the great info
I like chainsaws. Just subscribed!
Very well explained. Thank you.
Excellent explanation, thanks!
What does it cost to port a cylinder?
Great video.
Very informative
@WestcoastSaw where can I get a degree wheel and what else would I need to start porting my own saws and would you be able to help me out with information on how to do it
