Stihl Ms500i Build! Best new logging saw? 

A lot of guys just attack them with a Dremel.

Thank you. Maybe we can make that happen someday.

Aussie? If so we could send a package over and share costs.

Yap I've seen people running 42" on these. Pretty crazy for something so light compared to a 661/592 which is standard for such a bar.

@@em4703 I’d be afraid of it not oiling enough on a 42

​@@IndianaDoug It seems to be oiling my 36" bar very well (I run a 20 and a 36). I doubt loggers would use that if it was burning bars, anything over 36" gets expensive quick.

Thank you

They have a ton of intake. I think because of the injection they can limit the fuel at lower rpm to keep throttle response

@@dynojoemods2764 didn’t know that. Pretty neat idea. Can’t wait to see the 044 vs 400

Thank you. I would guess the oil it partly to blame on the carbon buildup

It’s the fuel ⛽️ pump gas and a slightly lean condition. I run motomix which uses STIHL ultra and on my mtronic saws there’s very little if any buildup on the piston and none on the combustion chamber. An interesting video comparing all the canned fuels after 2 gallons ….. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1JEXR-d6Z_Q.html …. Stihl motomix with STIHL ultra runs pretty clean as the video demonstrates. You run STIHL ultra with pump gas it’ll carbon up like a mother-effer so we can deduce it’s the piss poor pump gas and not the oil itself

Thank you

Nope

I am. Hope you are too!

@@dynojoemods2764 so far so good except this heat takin its toll on me!

Www.worksaws.com I have a few spots open in August.

Thank you

Thank you

2 completely different saws. Being m tronic I cannot control how/when the saw tunes. So power can fluctuate some from saw to saw. Same with the sounds. Sometimes they allow more free rpm and others keep it a bit lower "rich" Muffler mod is worth it for the less heat. And they normally gain .3- .5hp

A muffler mod on the side of the muffler instead of the front (like in the case of bark box and straight shot), will always give more power and less noise. The only disadvantage is that it's a permanent mod, so you can't just replace the lid of the muffler with the original one to get rid of the mod if you want too. Up to you to decide what's worth it.

@@em4703 I've been hearing that for 20 years, it would be interesting to see if our (because I believe it too) long held belief is actually accurate.

@@timdelph9048 It’s accurate mate.

They are thirsty...

The Egan and maxflow filter flow a lot better than stock. Seems to help more on the 90cc saws than the smaller ones stock. Once ported they all like as much flow as possible.

@@dynojoemods2764 I know the Max Flow are really good but I don’t want to run that after market shroud. I’ve been eyeing that Egan just for stopping fines from getting through. The stock one is a joke. Just wanted to see if you had any experience running an Egan on a 461 with the stock shroud.

@@sumdaiyze4632 Not on a 461. This 500i had an Egan filter. Looked to have some hours on it by the dust stuck to the outside of the filter. Inside/under the filter was clean as could be. No fines at all. I would guess the 461 to be the same.

That might be embarrassing, but I’d like to see what kind of gains he can get too.

Not sure the 462 can match the overall power if the 500i. Can probably match the hp, but not the tq especially down lower.

@@dynojoemods2764 for sure, such an odd duck design for Stihl.

@@dynojoemods2764 i figured, only thing worth mentioning is the weight. The mid size class never been this divided before 🤣

The 500i learns pretty quick. After the first few starts it is pretty well dialed in. It can be frustrating at times while it is trying to tune, as I am trying to load it on the dyno. As the saw is constantly chasing the ideal tune vs load.

@@dynojoemods2764 ahh ok, so you need to find a perfect Run where she‘s not trying to optimize Air Fuel. I wanna know how much Fuel it could compensate or even when the Porting is to extreme to get herself rich enough to run perfectly. Thanks for your Knowledge! Keep doing , there is nothing better as to be able to measure Results.

Other than the painted recoil, and plastic dye we did all the port work in house.

@@dynojoemods2764 i am in hopes that all your work will be as good as your Dino videos. I look forward to having you work on a saw in the near future. I checked your offerings on your website, but will need clarification about some offerings. Hope you will have time to discuss about the work by telephone at a later date. So you remember who I am, I am the fellow with an east coast (NY) accent who lives in Lafayette, CO. Thank you, Michael

All the runs in this video were from the black/green saw.

They do drink the fuel, that is for sure. I or really does depend how far you are going to pack, an extra gallon of fuel makes up for any weight savings

Ours was horrible on fuel at first, but does a lot better after getting some hours on the saw.

Sounds like it may need to go back to the dealer and be plugged in and reflashed. Could have an air leak or something too.

@@dynojoemods2764 Thanks, Joe. I appreciate your comeback! I'll check it out.

I also am not happy with mine, it's only got about 5hrs on it but it 4 strokes like crazy unless you're dogged in and pulling hard on it. Maybe it'll wake up later

Donny walker runs a big saw shop in British Columbia, and he has some videos about the 500i and some fixes that involve just letting the saw idle for 15 minutes to "reset." I sold my 500i right away. @@tyharland1906

@@tyharland1906Ours did that for about the 5 gallons or so of fuel. We kept running it and let idle several minutes (5+) at a time. Has more power, slight WOT flutter, and drinks less fuel. It also had good improvement after milling with a 42” bar on it.

I don’t get it either! I’d like to see the rest of the pro saws fuel injected or a fuel injected version like the MS261C and MS261CM. The TS400i/500i had been out for over 5 years before the MS500i was released. The 500i is more expensive now than when it was released.
