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

[bwalker]

Typically the bigger the motor the less sensitive they are.

 

[Ron660]

I have noticed some of the dirt bike oils slow the power of my hopped up saws ,

You prefer Dumonde in your 660?

It seems to burn clean with crisp throttle response but is expensive for saw use

If it's worth it I'll try it along with my 800 off-road. My wife is expensive too but she's worth it. I don't mind paying for quality.

 

[Ron660]

Mr arm wouldn't run full throttle on h1r. K2 it's fine.

Mike, what's your top three oils as of now?

I have been using the schaeffers at 32:1 based on Scott's direction since he ported my 361. I like it since it burns clean and doesn't make me feel sick.

And people ran H1R because Mastermind said so, even though others including myself expressed our concerns about the tuning/running issues. The schaeffer oil isn't going to blow up an engine, but it's not the proper product to use in this application, and it says so right on the bottle.

Y'all are still running around like chickens with your heads cut off. Carry on.

That about says it all.

The best I remember some of that decision was based on an airplane 2-cycle small engine test conducted with several oils and H1R was the winner.

But this is chainsaws.....

 

[KenJax Tree]

Airplanes engines way different than OPE.

But whereunto shall I liken this generation? It is like unto children sitting in the markets, and calling unto their fellows,

And saying, We have piped unto you, and ye have not danced; we have mourned unto you, and ye have not lamented. --Matt 11:16-17

H1R did terrible in that test too.
Airplanes are more like boat engines in the way they are operated. IE long periods of high load, high throttle.

 

[porsche965]

But lower rpms.

 

[bwalker]

But lower rpms.

The 582 Rotax turns about 7000 rpms and the last Yamaha 60 I had ran about 5600 IIRC.

 

[porsche965]

Is there any other two stroke engine application that turns north of 13,000 rpms like chainsaws?

 

[bwalker]

125 and smaller dirtbike motors, kt 100 kart engines to name a few.
The differance is they turn that rpm under load where a chainsaw doesn't pull that in the cut.

 

[mdavlee]

Mike, what's your top three oils as of now?

K2, R50, Mobil while I have it.

 

[KG441c]

K2, R50, Mobil while I have it.

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

North of 13k under load ?

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