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

Whoa!! That sounds good!! Ever had lettuce with cooked bacon crunched up in it and the grease poured over the lettuce!!! Wilted lettuce!! Real good but bad unhealthy!!! Lol!!

Makes me think of Tyrone Kentucky. Oh that's good.
You can eat like that if you work like few do these days.

What issues have you observed using H1R? (This thread is so long maybe you did address this and I missed it) Were these issues across the board or only at certain ratios? Chainsaw related of course. Thanks.

I did and posted pics. It's dirty burning crap and it inhibits combustion in my expiereance over several different bikes.

I'm still not seeing the elusive 30% claims no matter how many times I run my stopwatch. ??

Well, I'm not taking up for anyone but in the introduction the "stock" 661 clearly has the muffler modded so it ain't exactly stock (as it left the factory)

Oh man.......I love wilted leaf lettuce with green onions diced up in it......

Remembering that we are still just talking about one model.......the MS661. I'm not gonna say that 32:1 is a bad idea. I have no plans to stop mixing that way.

We were seeing blown cranks in 372s and 390s until we started using H1R at 32:1. Maybe that's because I use too much compression......but I'm not likely to change that either.

I am using 2R right now........and will be using it till I'm sure cranks will live with that oil at 32:1. The tuning oddities that H1R have has always left me wondering WTF was going on with it. At least with 2R I'm not seeing a lean condition when I switch a saw over from OE oils......

I'll like to see a few guys that run a lot of fuel make this switch with me. Run 2R for a few months.......and let us know how it turns out. I'll be asking around.

We are talking about mtronics saws here though. Reg. Carb saws have easily showed 30 to 40% gains over stock by just porting? By no way does this show that porting is a waste of time?

I like my ported saws

Porting saws is just a silly fad you know.

 

[porsche965]

Not according to those who haven't run one and then run mine

Are we seeing a pattern where Mtronic saws gain less than regular carb saws? Same thing with Husky's Autotune?
Strato is a good thing, but I am not sold on the compensating carbs just yet.

I don't think it's the viscosity only. I have ran other oils that have simular viscosity and they don't alter combustion.

R50 is incredibly thick an doesn't effect combustion. Klotz Super tech on the other hand effects tuning in the same manner as H1R.

 

[Andyshine77]

Red bull thanks again for putting this together. Like I said earlier the numbers didn't add up to what I've seen. As of now it looks like H1R may be the reason, in time we'll know for sure.

My stuff runs best on R50 or 800 off road @ 32:1
Nice and crispy throttle, smoothe high end ........... easy to tune and M-Tronic .............. they all run great on both. Much better than K2 and H1R ran.

Didn't the h1r make more power than the stihl mix?

The difference between running a 661 with a stock muffler opening like the first pic, and running a 661 with the opening like the 2nd pic is absolutely astonishing.

That really surprises me, as the 661 muffler is not stuffed up like most other saws. It has a large exit like older saws. I've personally not tested just a muffler mod though.

 

[blsnelling]

This is several times the area of a MS660.

The internal box offers no restriction at all.

I do not see performance differences with most oils, I haven't see any between K2 or R50.

motul 800, lucas, r50,h1r
I never have noticed any difference in performance using the four above other than the 800 smoked a little more than the rest did at 32:1
and i needed to get screwdriver crazy with the h1r had to turn it out the high side 1/8 -- 2/3.

 

[porsche965]

Ok, back to basics. All these motorcycle oils are the boutique of the day it seems. From one to another to another.

How about a traditional Chainsaw Oil made expressively for Chainsaws? What are the top two if one had to pick two? This could be started as a pole I guess. Go ahead anyone! Andre, you have pretty much tried them all. What do you think?

 

[porsche965]

So with H1R needing to turn out the H screw so far wouldn't the fuel mileage suffer terribly? What would be the point in that?

 

[Deleted member 83629]

i never did care about the fuel economy though i can tell you my lawn boy 2 strokes ran better on h1r than the rest
a bit less noisy and smoother. though the slobber from the exhaust is awful.
