MS660R VS MS661R ?

[Mastermind]

With a freshly spun loop of 33RSC on a 28" bar......in oak.

The stock MS661R



A heavily ported MS660R



It took some serious work......but I managed to beat the 661 by almost 2 seconds.

That just goes to show just how powerful the 661 is.

Hows about the ported 660 vs the ported 661 ? (when you get time)

 

[redbull660]

So maybe a muff modded 661 is as good as a ported 660? ... and that means a 661 ported oh man!!!


Got a feeling randy is going to be getting a lot of 661's to work on!


Randy - when you say heavily ported. What does that mean vs your normal ported worksaw?

Also, how broken in/tanks on that 661?

I'll set this round aside and hang onto it for that test. I've shipped out all the ported 661s I've done already.

What kind of money have you guys been paying for the 661's?

I've done 4 over the last few weeks. I think I've got them figured out. Notice I said think...... lol

 

[Mastermind]

That 661 is on it's first tank.......but the 660 is on it's second.

The jug that is on the 660....

Hey Ron you need too bring your 660 down when me and Keith cut You can run my
661.

So, a 661cxbti will eat a 660xb and 390xb and stomp them into the dust.
Also will have far better air filtration than a 390, and far less vibrations and better fuel economy than a 660

Damn, this thing's gonna be a mother humper

How about a stock 395 against both of them.

 

[Mastermind]

Bring one over.....

 

[William Balaska]

I wish I could, I'd like to learn a few tricks from one of you old hounds. I have had several 660 saws and a stock 395 just walked all over them, it's just night and day between the two. That 660 cylinder obviously has alot of bench time on it.

l like the fact that off the shelf the 661 is so strong and with a noticable power increase over the 660. As a worksaw the 661 will be nice with spring AV and better fuel ecconomy from the strato tech. l think with a 28" reduced wieght ES bar, the 661 has evolved to a whole new level like other models ie ms260>ms261. About time stihl upgraded this saw. My 2012 M/M porded 660 is wearing a 9pin 325 sprocket with 18" bar for giggles as it usually wears 20" 404 8pin. Quite a nice limber in 325! The more people talk about the 661, the closer l get to buying one. lt IS the most advanced 90cc saw currently on the market.

I want epoxy in my jug now

 

[Trx250r180]

I don't like the 661 even more now ,Thank's Randy

 

[William Balaska]

Yes the 661 is sweet by all means. I still love my orange brick. Here's one I keep tucked away in my bedroom closet.

 

[Mastermind]

Drop that thing in the mail.......I wanna play wif it.
