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

[Trx250r180]

I would not bother with the temp testing.
I have been dealing with Fluke and Raytek devices at work alot lately and have found them in general to not be very accurate.
Further does a higher cylinder cooling fin temp really mean the piston is hotter or does it indicate better heat transfer? I would also think the order the tests are ran incould effect both chain speed and temp.
Maybe we should put everyone's heads together and try and identify all the variables and then try to eliminate them or lessen their effect?

I think in redbulls bar testing the oregon one being aluminum was hot after testing more in the aluminum center vs the outer edge where the friction was ,the heat sink makes sense to me

I ran 110 Sunoco/87 efree 50/50 with k2 with no offensive smell at all today. Not sure what my buddy John was running but the 661c after the MM I did on it and recalibration with some runtime was very impressive. Seems to be getting stronger

Pic of the muffler opening just for you

Or is that the nature of this mix? It is clear on the transfer areas....bit heavy in the center. Wonder how the muffler box looks?

Stand by .............. I'll show you

there is some residuals in there from cleaning a little with compressed air. I have oil injection for air tools, thats the spots you are seeing

Plenty of protection there.

My vote goes to the urine sample for the win, I contributed that.

Who is paying for all this Red Bull?

Redbull has alot of time and money in this project. I have watched him do a few of his test. I don't know why he is doing all this but I know he goes to extremes to do it right.

For Milling have you reached equilibrium? Quite possibly.

I would not hesitate to throw her on a mill with my R50/800 off road mix @ 25:1. I just dont have a mill to run her on

Bailey's Woodlandpro Syn is the best bang for the buck especially since they have $2 shipping from time to time when purchased from Amazon. I'd like to see this tested too and I would be willing to send you a bottle of oil.

If this was analysing a urine sample it would be the most expensive p*ss in town. LOL

Redbulls Jaso certification: fb,fc,fd. Send your oil and a $50,000 dollar check for certification. Any donation over 50,000 will better the odds of your oil meeting fd certification!!!

Some people think that a piston can be bare metal with a high quality oil, but it's simply not true in practice. Even four cycle motors have carbon on the crown. The washed area of bare metal indicates jetting. Some times it takes awhile to appear, but it's a pretty good indicator of of an engines state of tune in a very broad sense.

I used to tell f my atv was jetted right by the heat marks on the pipe

sorry, i went back thread, and may have missed it.

red, will this be a cleanliness test? .......or something else?

closer look:

40% will see human face(s)
60% will see a piston burn pattern
8% definitely need a beer

.....or bad chamber design, poor transfer aiming, etc.

be back in a couple, to show example photo of above.

I have never seen a properly tuned motors piston with out transfer wash. Regardless of transfer port discharge aiming or the poorly design combustion chamber as found on chainaws.

And clowns..
