Stihl MS461 chainsaw porting... START to FINISH... JCS 

EVERYTHING YOU ARE DOING TO THIS SAW IS COMPLETELY STUPID....I HAVE A 391 UNTOUCHED THAT WILL RUN CIRCLES AROUND THE 461

Recently discovered your channel through your ms200t port for treeson. Thank you for creating these videos. You obviously know what you are doing and you present the material in a way most anyone can understand it. I have always wanted to get into porting. I have an ms461 so this video is a huge help. Honestly just from watching the ms200t porting video several times I was confident enough in porting my ms461 but this is one better. I have done quite a bit of research but nothing compares to the quality and value of information you present. Thank you

GOOD TO SEE SOMEONE WITH A CLEAN ORGANIZED WORKSPACE AND A EXCELLANT WORK ETHIC,2THUMBS UP.

friggin awesome. new arborist in training right now. dont have a stihl but dang, your knowledge and connection with the people out there risking their lives to save others.. honor. God bless your ability. thanks for the post up!

WOW, the throttle response is Awesome!!! Great Job for the Great people out there putting their lives on the line fighting fires!!

Awesome video man. Thank you for taking the time to make it!

If I fall asleep I'm still helping a great guy!!!

That’s how ya run a work bench! Nice and clean and organized!

I appreciate the long video, my knowledge of the 2 stroke is minimal but this is interesting and informative.

Always learn alot from your videos John. Great knowledge you got! Watching you all the way from Nairobi, Kenya.

Love this video. You kinda broke my heart when you said you wouldn't build one for milling. But, gotta respect your honesty. I'm a hotrodder at heart. I have no need for a hotrodded saw, but I have a want. I just think it's cool that you show all, or most of your tricks. You're one bad dude. Keep up the great work. Your work ethic will keep you busy!

I love the way the piston casting dust flys around and helps break in the main bearings

Never leave the oil pump dry… I use a couple big black Home Depot trash bags with a little tape between layers… you could actually ship it with fuel and it’s never letting out any odor… That’s a badass saw and I want one!!! Everything that you’ve said and done is absolutely spot on… don’t ever change your ways because someone says different… you’re on the money!!!

Great job mate,I have been running saws for 30 years,Walkers saw shop,west coast saw shop, and your self,thanks for who you are and what you give too people like me. Koala Bob

Definitely more in depth than my 461 builds. Looks like you are really squeezing some extra power from them. I’m happy cutting my bands flat. But I can see your logic in the way you cut your pistons and the benefits from it. Nothing but support from me brother. Glad to see a real saw builder finally catch on in this RU-vid crowd. Some of them tell me my doing machine work is pointless🙄

Hey thanks for the advice on the break in of a saw. I see so many people idle their saws for a full tank and never thought it was a good idea but now I know .... Thanks!

This was an awesome video, loved every minute of it. Thanks very much!!!!

Excellent work. Thanks for showing it. Greetings from Spain.

That’s just a beautiful saw…man!!! Wrap looks perfect!!! Man O man!!! I need to be dropping trees with one of them there saw’s!!! Boy howdy!!! I absolutely love it!!!

Stick it out… you’ll grow… your build’s kick ass!!!

I’ve ported three Stihl’s so far, and I loved every minute of this video. Good shit, John. Happy to give you another 90 minutes of watch time.

"For display purpose only" love west coast muscle saws too, good shit, old school!

I didn't get to comment when you did the build on Ms 500i for your buddy I think it's an awesome thing you did man you're one of the best at doing what you do keep it up I like watching your man God bless you need more people like you in this world.

Followed through on watching this video all the way through for ya, learned a lot in the process since I own a 461 and wish I would have watched this first hand. You probably hear this all the time but I'm a self-taught chainsaw mechanic and I've only ported three saws so far my 026, 036 pros and 461. Just would like to say thank you very much for everything that you do and for taking the time to make these videos that are very informative and unique. I'm a fourth generation logger that lives in Washington Pacific Northwest Forks to be specific and I've learned a lot of neat tips from different Legend timber fallers on how to squeeze as much power as you can from your saw and I'm with you for not wanting to just give away all your secrets you've been taught, some of them tricks are worth more than gold in my book. If you're ever in my neck of the woods would love to take you on a tour of the company I work for Dahlgren Log Co. and the shop I work at.We're in the process of restoring one of the world's largest yarders,Berger Mk6 and they own both quite impressive if I do say so myself. There's actually a video we recorded some years back that's on RU-vid I believe it's called flying the cats lol we shot a couple 527 cat grapple skidders over a quarter mile across a valley. I'm proud to say I was the one that made the spreader bar that supported carrying those suckers across. Sorry for writing a short novel but I have to say you are the man when it comes to Saw mods hands down and I believe you are going to make it big it's just a matter of time my friend just keep staying positive and keep up the hard work it all pays off in the end at least it always has for me most of the time with some learning curves along the way LOL. God bless and be safe out there, JH P.S. Let me know if you what you think of that short logging video

Video, video, youtube star, Ford Pinto, staycation? Happy to watch it all for you.

Sporty rick here from WLS... The original Saw Nazi 23 years.. hanging it up in 2 months, yes baby retiring! Just wishing you good luck... Like what your doin, but if doin production speed up the process, slapin the pin back in flip saw on starter side look down into the piston to align pin, also polish the baffle and sharpen the top edge of it.. stay away from raising the exhaust port too high, you want the pop to give as it will give.......................... cutters will be very thankful for the next gen of power hungry saw guru's Tomorrow have 5-500i's a 881 and a 460 in new condition Monday's not going to miss them!

John take it easy pulling those starters Man!! That's what they told me 30+ years ago but did I listen? Hell no and now at 64 I'm paying for it big time. Going for more neck and shoulder X-rays tomorrow, bummer

That looks like fun! I ported many 2 strokes in the past. Kart racing reed and rotary valve engines. Breaking exhaust at 90 degrees!

A SUPERB VIDEO ,OF A VERY GIFTED ENGINEER , WHO LOVES HIS WORK KEEP IT UP

I found out about you through the rebuild on Treeson’s 200. Glad I did but now I have gone down the rabbit hole watching all your videos and lost track of my Saturday! When the video started I heard a machine running and couldn’t figure it out, after listening more it was Bella snoring 😂

Watched this whole because of the love of two stroke engines. Thanks John.

Awesome work and great job on the video. I’m still learning RU-vid myself. I sure hope I can get a 661 done by you someday.

This is by far my favorite chainsaw porting video I’ve seen to date. This is my second time watching it! Love the channel & wishing you the best. Keep up the great work.

Love your sense of humour! Happy to watch start to finish Goodluck with the Lambo mate

I'm a Stihl dealer. I combed through tons of literature in owners manuals, service bulletins, training materials and service manuals. The only references to damage from running out of bar oil was damage to the bar and chain. I found nothing that mentioned damage directly to the pump from running out of oil. However, in the service manual for the MS461 under pump installation it says, "- Lubricate the pump piston with STIHL multipurpose grease". As a service tech I have seen plenty of saws with severely burned up chains, bars and chewed up clutch teeth and rim sprockets from customers running without bar oil for extended periods of time. Once refilled the oil pumps are usually fine when I test them. I've also seen plenty of failed oil pumps from overheating when people run their saws with the brake on for extended periods and I've seen oil pumps in fairly new saws that have never ran dry just randomly fail. Not much of an answer I know, I'll call tech line after the weekend and ask them for a more definitive answer. I would like to know too.

here's what you need is one of those adjustable illuminated big magnifying glasses that hang over your workbench, it ended a lot of my frustration with soldering.

This is my first video of yours that I’ve watched, I’m sure there will be more. I enjoyed the theory on port shaping and positioning, I’ll be going down the rabbit hole of understanding those concepts more.

I love 2 strokes and been tinkering with them since I was a little boy with my cox 0.49 baby bees ,good stuff I'm loving every minute of it

known and used chainsaws all my adult life and just by hearing the sound of your saws I can tell they are wailing, there's nothing like a good running sharp Stihl farm Boss don't really know what number that is and don't care, my personal preference anyway , thanks for something good and new to watch

I subbed and liked this video first 3 mins and Im committing to the ENTIRETY of it.

Awesome build!

I dome pistons in my CNC too. You are not alone. I also do a full combustion chamber shape to match the dome and resize to get the compression ratio I want.

I love the snoring!! Seriously though, an absolutely awesome video. Thank you!

Awesome video, Love the 461. I bet its a beast when ported. Thanks John

Great job specially for a younger guy he made that saw run perfect and last longer congrats my friend keep up the great work

For 🔥 Fire Fighter crews. Thats Awesome! Kudos contracts. God Bless Them. Great Job! I miss working on STIHL equipment

Thanks John. Awesome content 👊

Love your work John, was a great video!

Thank you for your time in posting this. I learned a lot.

What does one of those cost done like this?

Ha ha you had me cracking up! Video, video, youtube star, lamborghini! I appreciate the honesty so i liked and subscribed! Great video

I enjoyed that, quality work. 👍

I love the look of your muffler you should do a side by side stock to custom pipe! I want to see Thanks!

Don't know what other guys you talk about, I watch happy people who know what there talking about.

The parts of stihl saws that retain the fasteners do so so that they don't end up lost in the duff. If changing a plug on your tailgate or a stump people tend to drop stuff

Nice video, plus it was especially sweet because it was done left-handed!

I love the blatant honesty 😄😄😄 making videos is A LOT OF WORK for very little reward. I feel your pain 💯

Hammer Down brother. Start wearing gloves! I've been a mechanic for 25 years and wish I would have worn gloves from the beginning. Because now that I'm older my hands hurt and tingle go numb. I'll share and subscribe. Love the no bullshit attitude. Keep up the good work 👏

That’s a 14.4 snapper driver??? I really like how that works!!! Very awesome tool, right there buddy!!! Very Sharp Operation!!!!

Very well done video, you are very conscientious!

First time viewer but you did just pop up after a reg coats video I was watching, so your coming along and I'm going to start following you but I get the Lamborghini the third weekend of the month every month not just one month every month

There is always one who is jealous don’t let the haters get to you bro .you do amazing work .

John it'll come around you have to remember there's so many people making chainsaw videos , build a saw and send it to someone like Donny Walker , or tinman something like that you'll be famous bud .

great vid mate good to see how to do it we dont seem to have anyone in the uk how does chainsaw porting

Gave you a subscribe. Enjoyed the couple videos I’ve watched so far. Keep after it. You’ll be surprised how fast it’ll run once it starts rolling for you.

New subscriber. Used Stihl and jonsered to cut pulp for Brown Paper Co in the 70s. Best Regards

I would love to see an MS one on your channel

So I just finally finished this. Didn't pick up on you till after Christmas though I think. Thanks Guy

Thank you for your expert instruction. You rock

Good to see ya and I’ll definitely watch them because are interesting also hang in there all it takes is one viral video I would try RU-vid shorts and make friends hopeful shoutouts I believe in it 👍

50 years ago anyone who ported aluminum used rubberized abrasive cones for polishing, available at any good industrial supply store. Brand name is Cratex. They were essentially the consistency of a metal impregnated crayon, and easily broke under minimal pressure, or even with your hand. Probably why we thought they were actually made from clay and called them "crayons". They mount to screw tip mandrels similar to sanding or buffing cones without an extended pilot shaft. Step 1 of polishing would be piloted sanding cones or drums in varying grits prior to using "crayons" for mirror polishing the exhaust.

I cant believe you grind and file parts directly over top of a open crankcase

I have a 372 that I've ported and sha eved the head and made a dome top piston for and deleted the gasket on the crank case to reduce the size of the crank case and i would put it against any saw any time ohh and shaped the combustion chamber so at top dead. Enter there might end up being a open spot the size of your pinky nail

You're obviously very good at what you do but you should RU-vid videos because you enjoy / love doing them not because of money that will come in time. Everyone modify Stihl chainsaw I myself have a 361 Ported and am glad I found your channel. It's the little things. Thank you John

Looks good, this is sick

Amazing video ripper bad ass job

John, good info.

I put the chain catch on the saw side too. That way if it gets stolen it's easier to identify.

where are you located? And what is your pricing for the work you just did to this 461 in video?

O M G dude you Handel a chain saw with out a glove on your like a coved rebell.

I will be sure to mention you the quality of your channel and your overall lack of BS. That goes a long way here. I will also make sure that I mentioned you to my Subs which I only have twelve or thirteen hundred of but I got quite a few loyal guys in there that like to interact so keep it up, I was going to go into the same niche, but once I saw your channel I realized you've already got it covered buddy. A simple mention from somebody with a lot of Subs is enough to kick-start your channel quick. So make sure you're making good friends the guy who kick-started my channel. was aVe. Keep shooting and I'll keep watching

Another good video, I’ve never been into this kind of stuff but after watching Guilty of treeson video he did with you with his 200t and the NOS saw it got me hooked.

Have you check out Buckin Billy Ray or Tinmans saws you would fit right in!

Very good attention to detail

Watched the whole vide John, it was great info

Just want to say John you got a great Channel and you're going to go places with it for sure I still have a small amount of Subs and have been at it for a few years but I'm not very active for different reasons. The biggest break I got was when aVe mentioned a saying that I use in my videos from while back when I was way more active for a bunch of different reasons. My channel will be back up and running but I'm having some spinal cord issues so I'll still be out of the loop for a little while. Keep doing what you doing man!

Played it in thr back ground all the way through to help out

Great video sir, the dog snoring in the background has me cracking up 😂

Smooth runnin

💪💪 great video John

id throw a towel over that open case

You crack me up dude. you are a real talent but you are funny as ***** too with your sarcasm

Metal goes everywhere with a die grinder--down in my saw to!!!!!!!!!!!!! Keep clean stuff out of grinding area--old cat mechanic.........

Great stuff! Keep beefin' these saws up man!

Great video! I love saws, but I don’t use one very much. I do ride and work on dirt bikes and your video illustrates porting truly well. I’m watching all. Good luck on the Lambo!

Can't quite believe I watched all that, but reckon you deserve it 😀 You have some mad skills and knowledge. Respect. RU-vid ain't easy. Can't tell you how many times I've thought of getting into it and failed for one reason or another. Content and camera work. It's multiple skills at once. Keep on keeping on and, yup, people are 100% goofy! 😂 Peace from Scotland

I've ported a few saws myself and have loved everyone of them. My favorite is my 440 with a big bore piston and cylinder from a 660

its been 2 years since you made this i hope youre out there driving that new lambo

Good vid John. I learned a couple of things.

I like this Format. All Saws No Bullshit.
