Insane-O-ized Dolmar ps7910 Sporting a K&N

- Here we have a ps7910 Dolmar, fitted with the standard insane-O zipkit & fresh out of the shop. We obviously running her a little rich since this is the maiden voyage. I had a little more than 12% of a plan and fitted this saw for the testing with a Hi-Rev Saw Works design velocity stack and K&N air filter.
I 'm pretty pleased at how it runs in a blubbering rich state of tune.
As mentioned, it is the same chain as the 375xp video from around Christmas with a fuzz more relaxed grind (no material was added to the stops) and the chain cuts well. A little more refining and the chain would be a killer.
If you are interested the Dolmar velocity stack and K&N style air filter system, port work, or custom saw modifications, please shoot me an email.

That is a sweet setup for sure Jack! Thanks for sharing. Always look forward to your videos.
You are the master! Thanks for putting up videos. Them dolmars work good(especially once you get at them) don't ever see anyone runnin them in my neck of the woods
I own a 120 Dolmar, I bought in the early 90s absolutely wore it out. By far the best saw I've ever owned, I've cut more wood with it than I have all of my other saws put together and no that is not an exaggeration.
Ha somebody else that also loves the dolmar 120. I've got a 120 super that still runs pretty great but I hardly use it because I don't wanna wear it out much more
I have a 143 that I definitely need to use more, but theres nothing that big needing cut anymore!!! Its too heavy to haul back in where the big wood is...
Nice job man 👍 saw runs spot on I'm impressed the port work seams to make a huge difference nice low stump too love it man!!
Them dolmar saws sounds so good. Especially this one. Nice work friend!
NICE Dolmar!!! You can really make them run!! Interesting air filter with the K & N under the HD hood!!
I have had this saw for just over a week now. I just finally started leaning it out due to a rich mixture for break in and WOW! I have never run a saw with the responsiveness, torque, and muscle for size/weight as this one. It's my first, and now I won't go back to stock saws if you get a hotsaws101 modded saw you wont regret it!
There's a big vote of confidence right there, if I ever get a saw done I'll have to reach out to hotsaws101!!
In NZ no one runs ported saws really. I port my own and I will never run a stock saw.
John - Thank You for the post.
You sure do put some TLC into those saws.. I definitely have two saws for you to hop up.. thanks for the video friend keep them coming
Fine running Dolmar right there. Great work!
That thing rips! The power is right now like a light switch.
Things a monster! Love it. Good job!
I never heard of them till about a year ago i got a dolmar concrete saw in a trade and i love it the thing just out does all the other big brand saw that i have had seriously
Dang pard you got that dolly rippin!! Very sweet saw Mr Jack
Very nice! Absolute perfection
That thing is not missing a lick . Nice work .
I've never really given much thought to dolmar but your videos are better than any marketing they could do! I don't even need a new saw but I want one of these!
andrewford hi. With the right amount of massaging the 7900/7910 platform can be turned into a "lil buttkicker".
Thanks for watching.
andrewford80 I bought a Dolmar. I had previously used Stihl and I had a Husqvarna that was made in Sweden. The Stihl and Husky were great saws. My Dolmar would scare you. The rpms it’ll turn, more torque for those deep cuts I swear it’s the most amazing chainsaw I’ve ever had. And I’d never heard of em till just a few years ago.
@@BillyBob-ep7em never part with your dolmar they are totally underrated quality German machines
don't waste your money on a stihl or husky,the dolmar's are as good for 1/3 less of the money the other 2 are!
very nicely done
That Dolmar sounds great!!
Jolly good show Jack, sounds like your 7910 insano recipe is to the Dolmars liking.
I would love to see underneath that K&N to see what kind of velocity stack setup you have configured. I have been hoping that someone would improve on Dolmars HD filtration setup. I have never thought that the 90 degree turn their airhorn was very conducive to performance.
So Thank You from all the Dolmar Junkies like myself. I'm not sure if I can live without an insanoized 7910 much longer !!! Come see us, we'll leave the gate open....
Mine looks identical, beautiful saws,
That’s a wild dolmar very impressive
Awesome saws, great power to weight, love mine !
Dolmar vrh nema dalje
Good to see more of your work! Nothing like the sound of a genuine Jack the Ripper! Sry Stay safe and God bless my friend
Sweet saw! Nice face cut you know your way around the tree I see.
great saw!
just out for a rip r ya bud saw rips nicely well done
That man has felled a tree or two in his day. Made it look easy. No weekender can do that as fast and accurately. Help he had a freakin smokin saw and sharp chain!!
Wow, that is a hungry little guy
I gotta pick up a 7910… I had a 6400 and 5105 that I really liked. I’d like to have a Dolmar (Makita)
boy she really woke up when you adjusted that carb. in your experience how do the sach dolmars hold up compared to husky or stihl. great video love to here your creations get some work done
BLOODY RIPPA!!!
Powerfull
dolma is number one
Wow this is sweet chainsaw. I was just wondering if it's pretty good sawing down cedar trees from the southwest.
Would you mind going into more detail on the K&N addition to the saw? Did you make the intake? What is the part number of the K&N filter? Great videos, thanks for taking the time to educate the masses
Greg hi. Yes I made the intake. Thanks for watching.
that dolmar loves it's job haha
Can you give a part # for the unlimited coil? Please
What coil did you use to achieve the 13,500 limit? Are the earlier burgundy and black coils compatible with the ps7910 and makita ea7900 flywheels?
I like how you let the saw do the work. Some people literally push the saw (potentially binding the chain). One thing I love about Dolmar is consistent power in the middle of a cut (and the lack of binding or bogging down). If your chain is sharp, you're good to go.
Znači Bože , dolmar makita vrh
Runs good. Is the chip management any better on the 7910 or still sub-par to your liking?
Same platform as the 7900. Except for the fixed high speed jet carb, choked down flow muffler, recast (minor) cylinder exhaust outlet to mate up with the new design "tuned pipe" muffler, redesigned (lighter but less through flow) piston, and new (1000 +/- reduced rpm limited) coil, I have not noticed any outward physical changes.
Thanks for watching.
Cool
Sweet honey BBQ that thing rips
Just got the dolkita 5600 I want to put k&n on
👍👍👍
Very very nice
👏
Was thinking of port and polishing my saw. But I think they just need to breathe better.
Did you do a test after the port work and before the filter?
Jeff hi. The K&N filter setup has long been known as a bolt on performance enhancer in motorcycles, cars, etc. This is because of the element media material, design, and shape. If you take a stock saw and compare the difference between how a saw runs with the original oem fitment filter and a K&N, it will be noticeable. To answer the question directly, no I did not.
Thanks for watching.
Do you build saws for anyone or just friends and family
Nice low cut.
my gradfather was chain operator even he rembering dolma
I noticed that the stump shows what I earlier saw....you cut 60% into the tree with your felling notch. This must be a standard in the NW or similar with straight trees, but will almost always get you a trapped bar on an east coast tree, particularly a hardwood like an oak with misshapen crown due to photo-tropic growth pattern.
John hi. Not a standard. I cannot speak for others either.
It depends upon the lean factor of the tree. It also depends upon whether or not I want a certain thing happening at the stump.
I've cut old growth Live Oak, Black Oak, Chinkapin, White Oak, Madrone, and Tan Oak. Up to 6' in diameter. They sometimes grow like you mentioned. Where the bole can be 20' off the ground when they quit moving.
That is why I will assess the crown/lean with a plumb line. In order to get a face cut in the is deep enough to have the tree doing what I need. Also, I have my axe or a wedge in the deck cut watching for movement. Unless there is a massive rift crack that lets the butt split, you can usually get the face handled.
Thanks for watching.
Nice job and Video👍💪where did you get that wrap handle?
Karl hi.
It came on this version of the saw as an oem fitment part.
Stateside, they can be ordered from a dealer or the manufacturer direct.
Your name looks decidedly European. Across the pond, I have no idea where a guy would find a set.
Thanks for watching.
@@hotsaws101 ok, yeah I'm german. And its like almost impossible to get one of these and are extremely expensive. Thanks for answering
Karl hi.
Shipping to Europe is a spendy operation. It requires a special trip to the PO for a paperwork and inquiry session.
I have sent handle bars and saws across the pond. If your serious, I guess you could email me and see where the process leads.
Thanks for watching.
Where did you get the full wrap?
I notice the origon guide, instead of origin dolmar, why ? what size is that replacement guide ?
crystalgayleaddict hi. I busheled (piece work) for most of my falling career. You look for time & weight saving as a result.
The Oregon lightweight bar has much less mass when compared to a stock Dolmar.
I run LW bars in the woods.
Thanks for watching.
That filter is a nice idea, looks like it fits well. Do the 7910's have a bigger clutch cover? Although it was pine, it looked like it had a decent chip flow. I've noticed you've run just about all the common light weight bars. How does the Oregon stack up against a Sugi or Tsumara in real use? I might have to buy one of those Dolmar's just to have you go through it!
Buy an Oregon... check the chainsaw guys page for his vids on the problems with sugis...
I've seen his vids, run his saws, Hotsaws101 will be doing all my porting now. I own an Oregon, Sugi, and a few others but I'm not a professional cutter like Jack so I'm not putting 100's of hours on each bar yearly like he does. Both of my Sugi bars have been fine so far and made it through a couple pinces without trouble. Wish Cannon would build a light weight offering.
Thanks.
No they do not.
The pine in this location was worse than the fir and tamarack so I'm happy with the way it performed here (the chain).
The Oregon factory made 100 (green paint) liteweight test bars around '99 - '00. I ended up testing two of that lot.
The rails were like mush, and to a degree still are. For some applications they are the bomb - super steep/brushy/gnarly ground where you are required to limb.
The first Sugi I used was in '87 - a real 3' length (119 driver if you are running 3/8s) heavyweight bar. Bullet proof - 6 months and never touched it. Have not had one since that was that good. ~ '08 - '09 they had issues and the inside of the rails wore to quickly, imho (they did take care of that situation). The Tsuamras have good rails. Are less weight than the Sugi, and just about as stiff/strong. The guys that seem to have the problems experience the tips (both Sugi and Tsue) failing prematurely. I never noticed that issue but never used my bar/tip as a pry bar either.
I like the Stihl liteweight bars as well. The rails last longer than the Oregon by far and are not much heavier. Over all, I think the Tsumara bars are the best all ( they did have a short stretch where the inserts were shrinking but fixed the issue) around since the rail are bullet proof and if you finesse them the tips are fine. The down side becomes can you get the length and gauge you want/need. I like ths Stihl liteweight bars in second light, good rails and pretty stiff.
If my 2 cents counts for anything.......
Yea I've been wantin to try the stihl...and I've always wondered if the blue logo oregon lightweight is different from the red...I run my old 394 with a 28" cannon at the moment and I'm liking the stoutness of the cannon bars so far...round here stiff n rigid seems to be the ticket...
Interesting the Sugi "problem" should be brought up I noted that the tail of the bar shown by "The chainsaw Guy" had not been cut - I had a Tsu crack and thanks to Jack who pointed out the problem , no cut in the tail,a few moments with dremel and cutting disc no problems ! I have done in a couple of tips but that is down to a lot of the limbing I do is after a harvester has attempted to process the tree and failed, imagine a croc spinning a hippo around ! The limbs have such tension that its tough on the tip no matter what you do ! I can and do wear out an Oregon Power Match in about 6 weeks and after 3/4 weeks notice a fair amount of wear in the rails so m vote is Tsu. I have run the Stihl light as well and not bad.
What coil did you use to replace the stock one?
Early model maroon coil 13.5-13.8
Nice face cut
I was about to say the same. I remember my old man had a dolmar back in the day that he'd run a leave a 42 on all the time just in case he needed it. I'm partial to the 461s and 390s myself in the CRAP we cut these days.. but my lord does this make me want to look into a dolmar, thing seems like it pulls awesome. My question jack is would you put these dolmars built against built a husky or stihl? Or are they mire or less just someone who gets ahold of you wanting a dolmar nuked for the heck of it in your opinion?
The 166 Dolmar from the 70's "wood" pull a 42 pretty nicely in stock trim. Not sure if that is the saw you reference. The 133 was a little small for that application, imho anyway.
The 7900/10 has both good and bad points - as do all saws currently on the market. The Dolmar/Makita can be made into an animal for sure. It just takes a lot of work to get it there. A 78.5cc saw that weighs in about the same as the non-strato, early 372xp and ~ .5 lbs less than the 460/046. I think they have a little more than the 461/460, which has a little more than the 375 (372xpw) equally "did". Contrasting, They have the weakest spring mounts of the middle weights and you best not be rough on your equipment lest you be replacing motor mounts in a real regular fashion. Internally, they are built more like a thoroughbred than any other saw I have ever seen - for speed. Part of the reason they weigh in at so little. Conversely, they will wear out faster because of the "thoroughbred design". Pistol grip has the best shape of any saw, period. Clutch cover has the worst shape/design of any saw, ever. It's a trade off, as with all things.
If you are thinking about building a saw, please shoot me an email. I could blather on and on.....
Thanks for watching.
hotsaws101 we'll "I try to finess" anyways so I may have to look into one of these. How much would i be looking at for an overhaul? The 9s?
If you end up getting one and need an assist please shoot me an email. Thanks.
what 2 stroke oil are u using mostly, and what ratio.
African Twin hi. czcams.com/video/XIxgOQ4GsNM/video.html spells it out.
Thanks for watching and blessings to you on this day.
Why is there an extra foot taken when bucking a log for hauling to the mill?
Outdoor Frenzy hi.
Trim. For cuts (kerf loss) that the mill takes sizing log to millable lengths + cuts on end/s of log that are not perfectly square. Sometimes checking too.
Thanks for watching.
hotsaws101 thanks for the videos and the explanations.
How do I get this done to my saw? Makita EA7900PRZ2?
65BAJA hi. You would have top contact the guy that did this one I guess.
Thanks for watching.
what oregon bad and chain do you have on that saw?
Hello. Are you asking what the length the bar is? 32" if that is the case. I'm running a Windsor chain here.
Thanks for watching.
what 2 stroke oil do you use,prefer?
Arpad hi. czcams.com/video/XIxgOQ4GsNM/video.html spells it out.
Thanks for watching and blessings on this day.
what do u think about amsoil 100 to 1?.
Jack, are the new Dolmars as good as the old ones ?
They are not as bullet proof as the old ones but don't weight nearly as much either.
Thanks for watching.

I was expecting more.
ohhh she cuts
My Dolmar makes my buddies stihl look childish. Stihl and husky are all marketing, if you want a real machine dolmar/makita is the way to go.
Do us all a favor and buy a good quality microphone !!!

That is orginised worck little chainsawe for little cuts ,, its on fishing ,,not on wirck...?...big caw urs for big worck...keep yore hand end spin in healt little longer..to much hawy worck on the end alwys take a price...sometime end to expensiwe
when the person felling a tree is INCOMPETENT to do it safely, but in MITIGATION he is too ignorant to understand how lacking he is in any skills.
So that all the folks know how this started out, and maybe learn from my experience. And buddy, have the kahunas to let your scolding stand....

Oh here we go... Not sure how things are done over in Whooville. Out on the West Coast it's not up to me to make sure you don't hurt yourself by being an idiot. You don't sneak into a person's strip unannounced. You make yourself known by letting the faller/s know from the landing or another safe spot BEFORE going into the strip. The animals are smarter than that as well. Thanks for watching.

I'm going to help with a learning moment - Back ~ '06 in early May on Walker Ridge (headland ridge that drops off into the Pacific). I'm inches from the top on the West Southwest side of Lady Bird Johnson Grove. The strip was laden with Huckleberry & Rhododendron. Sawing from tree to tree was a necessity. A pretty severe Sou'wester was blowing. My strip lay (the way the ground was contoured) was such that timber had to be sent to the West Southwest. In other words, straight into the wind. I'm having to set up a ½ dozen or so trees and then get back in behind them and pound them down with, well,,, anything I can find to go into the wind. That part was a waiting game. Every so often the wind would subside enough to wedge the pounder tree into the poundee trees. What this means is that that day, the most dangerous job in America any three out of four years you look at the census bureau just became exponentially more dangerous than a "regular day". I had a 30/32" fir set up. The tree was a three long log & a shorty specimen. As I'm "working" this tree into the wind in between gusts I just happen to notice an orange hardhat with some glasses & silver hardhat poking up just above the brush about 75/80' DIRECTLY OPPOSITE THAT OF THE WIND. In other words, they were standing in head deep brush, with no way to move quickly, in the ABSOULTE WORST place to be on that day. Now, I'm committed with the pounder tree at this point. My pounder tree is, like all the others, working back & forth in the wind gusts. It is borderline too windy to be working, but, we had missed a lot of days during the winter to weather and like most others, kids need food, clothing, and shelter. I had the pounder tree pretty well set up and it didn't take long until the whole mess was on the ground. Low & behold, here comes the cutting boss for Green Diamond. Along with the pole buyer for Sierra Pacific. I proceeded to explain to them, but mostly the cutting boss, at a VERY HIGH “OCTANE” LEVEL WITH ENTHUSIASM, that what they just did was one of the more stupid things that I had ever seen in the woods. I actually yelled in the cutting bosses face - DON’T YOU EVER COME INTO MY STRIP AGAIN UNANOUNCED, EVER!!! I did it twice to drive the point home. I continued along the lines of, had a big gusts come up and pushed the trees over backward they had absolte no way of quick escape. Would it have taken another 5 mph higher, 10 mph higher gust to come up and push those trees over on top of them. Who knows. Would it have been “das-asterous” though. That I can Guaranty. In late March of ‘08, I was standing toe to toe with said cutting boss. I asked point blank “Have you ever felled a tree?” The answer was “NO”. So now the previous “day in the woods” snippet makes more since… As a faller, I am responsible for not hitting what I know is there. By your logic, I’m also responsible for everything else. Even the idiots out there that do, and let’s face it, really stupid maneuvers. West Coast etiquette requires that I absolutely make sure the faller knows I am coming into their strip. If nothing more than to get the best route. Worst case scenario, I get to heads up that there is a tree headed where I stand. I am sorry if you do not understand this part. Unlike what is going on in this world, and it’s rampant, I need to take responsibility for my own actions. Especially “out in the bush”. Summing it up - What I shared here is just one case where a bad choice was made by someone. I had no control over that choice. God was smiling on those two that day and they lived in spite of their VERY POOR reasoning. Would I have felt really bad had it gone the other way, YES. Would it have been my fault? No, not even. Hope this helps you with the delineation of who is responsible, liable, for what.
My 7910 cuts faster,your chain is not good. Check it out.These machines are beasts i bought two off them thinking i am gonna kill the first one quick well hell they last and run fast.
I really doubt that....
