Actualy I just got a end of year sale flier from madsens.They sent a $25.00 off coupon also.A 385 with a 32inch bar is down to$699 with coupon.395 is at $859,and a 372 at $ 559 all include 32 inch bars.I got a madsens power tuned 372 and am very happy with it,but I really wanted a 385 but none could be found in my area.(I got it in April 2001).I also kn ow a guy inCanada who got me an 088 for $995.00 brand new.I think he must make money on the exchange rate,but was a gooddeal for me.

DanHello Everyone,
Know this fellow Sawracr well, Jon Rupley has some awesome running saws. his 3120 husky and his 090 Stihl are unbeatable. he usually gets 1st or 2nd in the modified class when he runs. now when he says he powertunes his 385 husky thats not the same as madsens powertune. all they do is pull the barrel and check the base gasket for alignment and put a port in the muffler. 80.00 thank you.
Jon workes at a husky- stihl dealer as a mechanic in placerville california. when he powertunes or modify's his 385 husky he changes the intake timing, transfer timing, and the exhaust port timing.then he mills the base of the barrel for more compression and less squish clearance, changes the ignition timing, ports the muffler and massages the carb. he's probably getting 9-10 horsepower out of that saw and the 066 stihl drivers wont be able to stay with him. he knows how to make those huskys run

I know, thats why I recommended to JPS to go to Madsens. For $80 its not a bad deal and the saw will run better than stock. He needs it to perform every day when needed. Madsens is the mildest of the "power tuners" but they do good work.

To kdhotsaw and sawracr(or anyone else) is it better to have a brand new saw modified or one that used a little bit.I was thinking of getting HUSQVARNA 385 and having it worked on.Can you really get 9 to 10 horses out of a 385 and still keep it's reliabily.If you can,is anyone interested in an o88.Just wondering,thanks. Dan
DanGood Day Dan, even tho the factory has left lots of power in a stock saw, as we increase horsepower the power band becomes narrower. Increases like Ken are talking about may not be practical for tree service work, but the guy knows his stuff, he studies small engine, motorcycle, karts, and our favorite chain saws, he has notes and grafts on everything he's built.
Because of the basic design of the 385 it dosen't take much work to make them bark, and as most have found, a lot of horse is held up in the muffler , or the 372 for that matter. Got a guy out here that uses a 371 for falling in the woods, doesn't have the stump of the 066, but he makes up a lot of time limbing and bucking, seems to cut just as much as the guys with 066's at the end of the day, and dosn't have to pack the weight or gas.
But the best part is he's run the saw three seasons. Try one you'll like it, and best part your buddies will be IMPRESSED ! Jon

sawracr,I have a372 that madsens powertuned,but they did not change the muffler any that I can see.the 372 is my main falling saw,along with an 046.HOW much narrower does the powerband become?Pipey like a 125MXER (NO BOTTOM OR MID RANGE).If I had a complaint about the 372 it would be the lack of mid range power.(compared to the 046)Is there an easy way to uncork the 372?Or would it be money ahead to buy a modified muffler?I have modified many of the bikes that raced over the years,but haven't played with the saws much.thanks for your help!

Definitely get that muffler done. Walkers saws shop always includes muffler porting do to the significant gains. Also it is the best way to help the saw get rid of heat. The gains will be recognized across the whole powerband

the muffler tune is worthwile- easy to do too (cheap) - otherwise you might as well buy a bigger saw. if you run a 3120xp or a 088 and need more power you can read the posts above and get your saw tuned with their recommendations - kick butt powertune costs around $300 - thats the difference between a 385xp and a 3120xp...
hello dan,
If the muffler on your 372 doesnt have a extra port in the muffler it needs it. your looking at a 15-20 percent increase in power. if you do the other mods to the motor for a good falling saw your looking at another 20-25 percent power increase. then the saw will run right with a 066 stihl or a stock 395 husky. these mods will not decrease engine life. I have a customer in Idaho that is still running his 371 after 4 years and we did two 372's when they first came out .he runs these saws every day and they still run fine. If you put too much exhaust porting In your motor it will get pipey. you only want to do that if you want to go racing.
if you have more questions or want prices on these type of modifications E-mail me at

P.S. once you run a modified 372 you 'll be very very happy

Thanks Ken,and sawracr.I'm just like most guys looking for some kind of advantage in saw performance over your peers.The saw works great now,but a little more power would be great.Tundraotto,a pipey motor is a motor that runs best only at high rpms,little or no useable power down low or mid range.That limits how the motor is used,wide open all the time = racing Dan
DanHello CMBetz,
Stihl and Husky have closed up their mufflers in order to help meet epa emmision levels. 25 to 30 percent of your air-fuel mixture goes out your muffler unburned. by restricting your muffler and keeping the mixture hot they can reburn some of it and lower their emmision levels but it plays hell on engine temps and exhaust restrictions. by adding a port or opening in the muffler you lower the restricton and it runs cooler. most of the late model saws pick up 15-20 percent horsepower and run cooler. the 066stihl and the 056 stihl are the only saws that I recall had daul exhaust outlets

But I thought you guys liked HOT saws?
Hello John Paul
Its like president Clinton's defination of what is is. A hot saw is not a plugged up 066 stihl about to melt the piston. When you fire up your mac 125 Kart saw that your running alcohol with 5% nitromethane and it hits 13000 rpm , then the crowd all stand up to watch you make the cut and the noise can be heard 2 miles away well now thats a hot saw!

So what is the cost to build the MacHotsaw?
Hello John Paul.
Its pretty spendy if you go the whole nine yards. First you need a good kart motor to start with. Then you have to do the modifications to the ports and cylinder head, build a header and pipe, install a v-12 gem reed block and daul 360 tillotson carbs and linkage, and then get everything working in harmony. you'll probably have 650.00 in parts and about 600.00 in labor. 400.00 more if we furnish the mac kart motor
Sending you a photo of jonathan hobbs - HOMEDELITE MAN'S homelite 2100. its got all the good stuff. its pretty scary to run. he's cut a 2.5 second cut in a 18 inch log. pretty fast.
