hello dechsi87 did you edit the lid of the HD air filter or is it the original one? I ask, since the HD air filter covers are always so shiny and not dull black. Cool video👍🏻
Check out Hotsaws101, he's got a video of him runnin a 500i, 572, and 7900 against one another and the dolmar holds it own pretty damn good against the other boys.
Seems to me that you're getting more pep on the low end, that "brap" when you touch the throttle is a sharper upward curve compared to stock. Did they work on the intake/exhaust timing as well during the port/polish?
Hi mate, I'm in Bavaria working as a baumpflege and have a saw needing woods ported. Do you offer this service? Good work, I have a 36" castanea tree needing cut down. Would a ported Makita 7901 handle this bar? Cheers, schones wochenende.
Hello, really nice video and good porting work ;) ! In your opinion for a stock saw, what is the best choice between a 390 xp and ms 661 CM ? The stihl is more powerful on paper, but the 390 xp seems more "agressive' in the wood. Thanks !
Depends on personal preferences, both are good saws. Stock vs stock the 661 has a bit more torque in the cut. The 390xp has the better handling and way better air filter system. So overall the 390xp is a more complete package in my opinion.
I have a makita saw myself and they seem to be very good but the reason alot of people go for Stihl or Hasq is parts availability and parts price. If you can't afford the first two or do not have good reason to lay out for the 'Top Two' a Makita saw is more than adequate for professional use if you pick the right model and to be honest its not because the sawd are not good its more to do with Makita been known for its power tools.
Very true here in Australia. The Dolmar brand is really not known at all. I have two Blue Makitas DCS-34 and Dcs 7900 with 24" bar. "Dolkitas" always cut faster than Stihl because they pull a thinner chain through the wood. Sometimes you actually have to show the label to people who refuse to believe they are made in Germany...in Australia Dolmar is heard as an Asian sounding name!!!.
Stock 7900 in my country is 5.8hp and 6.6kg. Same specs as Husky 572xp. Stihl advertises 6hp at 6kg for 462 i wonder how this is going to work in the long run. I have makita 6100 stock love the saw it is enough hp for my 45cm bar I use it for feling and limbing. But if i had an option to use 2saws i wuld use 7900 for feling and something like husky 550xp for limbing.
i think you talk about the new "7910" version with 5,8/5,9hp. It has some restrictions to the muffler in comparison to the old 7900 to follow new emission requirements, but nothing you can't change easily ;)
The intake and exhaust ports (the holes in the cylinder where the fuel and exhaust fumes circulate through) are enlarged in a skillful manner to increase the amount of fuel and air that can circulate through the cylinder per one cycle, while also optimizing the timing. It means more fuel and air can circulate through the cylinder, lowers temperatures, increases compression and, ultimately, power.
It shouldn't really matter, just tune the saw while buried deep in wood. You won't come close to the limiter rpm that way and you can get perfect tuning for maximum power. Unlimited coil is only good if you tune outside of wood.
@@bennyblanko3 yes sir.!! If you really want that saw to cut you should get in touch with the guy that does all of my saws. I’ve got a 7900 he did for me a few months ago and it’s quite impressive. Check out his channel (Kevin LaVanway)
@@JS-oy6nn Thanks! Yeah, he sure turns them up!!! Not quite ready to send it out yet. Mine is fairly new, but kind of a dog for 7900 ... but I think gutting the muffler will help - but then there is the step out the exhaust port to smooth - and if you do that, might as well do the transfers and intake, and time the whole thing too ... where to start and stop? I don't want a race saw ... just firewood ... but the muffler sucks on the Makita ones.
i only have some dry numbers of the powerheads, but i'm sure the 572xp would be heaviest of them, the stihl the lightest one and the dolmar in the middle.
You can't compare wet weight. If one manufacture puts a larger fuel and oil tank on for longer cut times, then you weigh it and it weighs more, people will criticize it because its heavier. Most people are too blind to take this in account.
This must be an older 7900 if it has 6.3HP stock as the new ones are only 5.7HP? I want one of these saws as they look cool as hell and are built very well.
Chris Gilliam Man Stuff I ended up buying a Makita EA7900PRZ1 shortly after posting this. Just cut up about 7 trees on my buddies farm this past weekend with it and my Echo CS501P. It is a beast but a little on the heavy side especially after using the Echo! Great saw none the less.
@@Brian-Outdoors Outstanding. I have a job requiring the removal of a bunch of huge pecan trees. I hope I can make money on the wood, cuz that $1,000 saw hurt. 😉
Cool. Do do you tuning for people? I'd be interested. I've got a few saws I'd like doing maybe😆, there's a few good tuners in the states but the cost of sending from uk would be a lot. I'm guessing you're in Germany?
Both are good saws,but even maintenance items are harder to find for makita saws whereas stihl parts are a dime a dozen and stihl dealers are everywhere. I have an old dcs520i that was a great saw but parts are obsolete. I've also got a ms310 that I ve used very hard over the last 12 years and the only thing to fail was the ignition coil. A makita will be faster,but a stihl is still a great saw.
it means the saw is modified to a certain degree (modification's of cylinder, piston, ignition, carb, exhaust for example) for more power but still has a all day work ability in the "woods" without loosing much durability.
@@JMGeranimo i love the 395 an the 7900 . Would be tough choice but i wonder if the 7900 would win over cause theyre so irresistably Smooth . Never seen aroun here tho

@@johnharrington7116 no, you tune properly after 5th tank. things need to properly seat themselfs, they come rich from factory to improve break in period. all instruction manuals say : no full throttle without load in the first 3 (to 5) tanks.

I have 3 of them there one of my favorite dolmars
Beast.
Damn that baby rips after the porting. Alright that's it. I'm getting one too. Even tho I have an echo and husky. Needing me a Makita next.
Would be cool to see a comparison of Stihl 462, MS500i and Husqvarna 572 as well as Dolmar 7900 in same piece if wood with same bar and chain.
7900 will out cut all of these saws. I had mine specifically ported to be a 500 killer so to speak. I call it the bulldozer
@@JS-oy6nn I've seen some pretty stout 500is lately. It would be a cool test to see.

Hoped more, but i will try somerthing different in the next one 😉
@@Dechsi87 if i do muffler mod and take out SLR in muffler on makita ea7900 do I need to adjust the carb or not? Best regards!
@@dolmar7900 yes,it must be richened up,especially on the high side
Do these saws still have a carb with adjustment screws or have they gone with some sort of autotune/m-tronic BS?
regular carb. Makita / Dolmar has not autotune (yet ;-)
Deveria fazer comparativo com sthil de mesma cilindrada e husqvarna também de mesma cilindrada
OMG 😎💪👍👌
what does it mean that it's ported? what is done too the saw when ported?
The intake and exhaust ports (the holes in the cylinder where the fuel and exhaust fumes circulate through) are enlarged in a skillful manner to increase the amount of fuel and air that can circulate through the cylinder per one cycle, while also optimizing the timing. It means more fuel and air can circulate through the cylinder, lowers temperatures, increases compression and, ultimately, power.
What kind of wood?
Man that sounds good ported!
Can you give me a part # for unlimited ignition coil?
I got ea7900 and need more rpm.
Thanks
It shouldn't really matter, just tune the saw while buried deep in wood. You won't come close to the limiter rpm that way and you can get perfect tuning for maximum power. Unlimited coil is only good if you tune outside of wood.
Put a husqvarna 272xp unlimited coil on it.

It wuld be interesting to see how much 7900, 572xp and 462 weight is with full tank of gass and oil bar and chain on.

good job on trying to kill your saw running it wide open for so long on the first tank.....
Nathan Van de Velde do you recommend tuning it at half throttle?
