What's your favorite 70cc saw?

[MustangMike]

IMO, 460s, 461, and 7900s are 80 cc saws.

You are not the first one I have heard being impressed with the 6400.

They're under 80 by a touch. By that a 290 is a 60 cc. It's 56 and runs like a 45.

 

[MustangMike]

I think with the 039 top end it is a 64 cc saw that runs like a 50 cc saw!

Then a 357xp and 359 are 50cc class saws?

To me yes.

 

[dustinwilt68]

Strange, no one ever runs them against 50cc saws in the shoot outs. II guess that's why I put them in the 60cc class, but they are the best 50cc class saws by far, no contest, many consider them the best 60cc saw. So if they are considered 1 of the best saws in 2 classes then they have to be 1 of the best saws ever I think.jmo

my 61/266xp husqvarny
acts like a 70 feels like 60

I've been using my PS-6400 for the last two days.
I just love this saw, sports more grunt than most want to admit.

Is she a 70cc class saw?
No!
Is she as strong as her sibling PS-7900?
No!
Will she cut through a oak knot with her 20" B&C setup fully buried?
You bet she will!

Sorry, no video and forgot to take pictures after bucking - but that log is gone now.

I lately started to pick my PS-7900 over my PS-6400 for any and all jobs, super fun but complete overkill!
The PS-7900 simply can't be loaded with just a 20" B&C setup, she barely feels pulling a super aggressive 72DL chisel chain.

That been said, yes my Dolmar PS-7900 is still my favorite 70cc class saw.

EDIT & P.S.:
I just realized I haven't taken any pictures featuring my PS-7900 in over two months.
I'll have to correct that.

Throw an 8 pin on that 7900 and play with your rakers. I alway use to set all my rakers even at .025 for all saws. It wasn't until I had some seat time with the 7900 stock that I decided that it needed a better chain. My cutters were sharp but it did not quite feel right.

I just took a few swipes of the rakers till it felt right and it would self feed very well and it was a good amount faster IMO.

I put the same chain on a 562 I had at the time and it was to much for The 562 if I went to apply moderate pressure, self feed was fine it would just load it to much sometimes. I think I am a touch below .030 and it cuts pretty smooth still but not square smooth lol

I am no chain expert by any means, I am trying to file square, but it does appear some chains even in that aspect of filing can be more suited for one cc class of saws compared to other cc classes.

My ported one wears a 20" bar mostly and with an 8 pin and rakers set right for it, it will just chew through anything with a respective amount of torque to spare.

The bigger saws can get away with lower rakers it does seems.

I remember Deets had a square .404 chain with an aggressive angle and he even said it would suck the power right out of The hybrid unless he held it back.

grab a file and experiment is my theory on chains. Even round chain can cut fast once and a while lol

Racing is done by cubic inch. 50.1 and down is 3 cube. Up to 65cc is 4 cube. 66-81 is 5 cube. 82-99 is 6 cube.

Did not know the racing breakdowns, thanks for that, but 15 cc is a big range. For informal stuff, most people seem to go by "10s", but I see some people thing 50 is 50-59, where others (me included) believe 50 is 50 +/-5, etc.

As long as everyone is on the same page.

Minnesota does some on the 5s. 45-55 and so on. I like doing it on the cubic inch.

I like the +or - by 5 idea, think it works well.

If you're a fairewood hack with a beater truck, this is all the saw you'll ever need...

Thats a beauty

Or an 044!

This would have to be my favorite. Even though I've never ran it. Lol

I have a 8 tooth sprocket for my PS-7900!
Tried it and didn't like it in the oak that I buck about 75% of my saws workload.
To my limited experience round filed chisel tooth and 8 tooth sprocket do not perform very well in knotty oak - thus I just use the stock 7tooth sprocket.
8 tooth sprocket works nice in fresh beech, but I don't buck much of it so I don't bother with replacing the sprocket in the first place.

I do make my PS-7900 72DL loop more aggressive than the 72DL loop that my PS-6400 is a pulling.
She's a big girl and can take the additional load without breaking a sweat.

Or an 044!

That 044 is what convinced me I needed to graduate to 70cc's (+).

A buddy was running an o44, I was running a 2159 (at the time my "big" saw), cutting Hickory. Before cutting with this guy, another buddy's o36 was the biggest saw I'd cut with..and his 036 was always so dull and neglected it wasn't even interesting, although with a good chain, it did seem to out cut my 2159 by a small margin. BUT that 044 !! I gave it a go and a light bulb came on.
I started hawking firewood that winter and bought the 2171. (local Stihl dealer has always been a prick, that's why I've always bought Jonsereds)

 

[greendohn]

I'd like to mention, local Stihl dealership is under new ownership, seems to be a good kid, I hope he can make it a successful business.
