661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[Moparmyway]

Hard to beat that R50, what do u like about the k2?

K2 doesnt make me sick after running it all day ................ I find that I am gulping for fresh air after running R50 for any extended length

I love how R50 runs and how it looks inside ................. but the smell definately gets to me

Hadnt noticed the smell much at all but all of it chokes me if I get cornered with it. Cant be good to smell any of it though

Flush cutting a stump i think any oil is enough to kill you with the exhaust blowing right in your face.

Ya and its hard to get your back to the wind sometimes. I do remember H1R being alil more irratating than others and being the reason I stopped using it. 800t didnt bother me much but Ive heard others mention it does but I think it has alot to do with wind direction and avaliable space where you are cutting or it all chokes me

North of 13k under load ?


My 066 and my 661 pull over 12k in the cut with .404 and a 7 tooth sprocket

Stock motors? What size wood?

K2 is good stuff, just wish the cost was a bit more sane. However, if I was running it in just saws the cost wouldn't bother me as much.

661 just has a muffler mod and runs a Max Flow air filter
066 ported by Mike Lee and running Max Flow

All sizes of wood. I cut lots of stumps ..................... but running 36" .404 7 tooth setups

I have seen a 24" DBH tree have over a 50" wide base, so its tough to answer directly.
Its not like blooms are consistant in size, but they are definately consistant in being tough.

I am supprised at this numbers given the substantial wood. I would have that they would have been lower.

Me too, but the Hardlines dont lie

I tached some saws yesterday milling. They were pulling 8-11k in the wood. 394 with muffler mod and a ported 880.

That's been more in line with what I have seen,.although admit ingle I have only tached a few saws in the wood.

 

[mdavlee]

There were a couple around 11.5-12k

- I decided on doing the test with .404 Stihl RS chains. ...I think the 661 has so much torque that you need to exert more than normal pressure on the bar to get it's max potential out of 3/8ths RS. While the bigger teeth on the .404 offers enough bite for the torque of the 661...so it's normal pressure/self feeding - more consistent...especially a ported 661.

3/8 is entirely adequate to put a proper load on any saw, even a ported 880 or 3120.

Brad did I hear u say one time that with magnum spikes on a saw such as a ported 390 or 660 that u could stall the biggers saws when pulled hard enough on the spikes?

 

[blsnelling]

You can stall a ported 880 or 3120 without the dawgs.

That was my thoughts but just makin sure. Thanks

Hi Brad,
I have to lump in with redbull on this one.
My 661 likes .375 no doubt, but there is a rather large difference in how it runs 3/8 compared to .404

With .375, I was allways leaning on the saw
with .404 I usually just hold the trigger and laugh

 

[blsnelling]

That was my thoughts but just makin sure. Thanks

It's all in the chain and the operator, and 33 or 36 RS is plenty aggressive right out of the box. It's up to the operator to be able to feel and listen to his saw and operate it accordingly.

Id like to try 404 on my 390 with a 24 b/c for noodling

 

[KG441c]

1. do you have a .404 bar for a 661?
2. have you ran .404 on 661?

I've personally ran .404 and 3/8ths RS, RSLF, RM and customized RS half skip on 20", 24", 28", 30", 32" 36" and 41". On the 661.

I'd rather not have to apply pressure that is required with 3/8ths on a 661. I'd rather use the .404 wish is pretty much self feeding and more consistent than trying to apply pressure on a 3/8ths chain.

What you are saying is incorrect and that's just the bottom line. I doubt you've even run 404 on a 661. You have to press on 3/8ths to get it to cut as fast as .404. ...on the 661.

3/8 RSLF requires the most pressure
3/8 RS H next
3/8 RS next
3/8 RM the least pressure required to get it to cut fast and right.

So Redbull the 404 self feeds better than 3/8?
