Whats the better oils these days for 2 smokes? Back when I raced, I always ran Yamalube. It was recommended to me by a factory mechanic and my top end always lasted with it. A lot has changed in 15 years though and synthetics have come a long ways. What do you guys like?
I also don't want anything that says to run at 50:1 or some crazy ratio. I ran 40:1 back then, I'm running 36:1 now. I'd like to stay between 32:1 and 40:1.

Maxima cator based 976 ? is also a very good oil.

With that being said, I just switched to Maxima K2. Stupid? who knows. K2 is highly recommended by a lot of people with 2 things being better than 927
927 can separate at temps below 35 degrees and the carbon I mentioned.
K2 is suppose to solve both these problems....we will see.
The pro for 927 though is it is designed for extreme use performance, hardest of the hardest racing conditions.
But, today almost every oil is of awesome quality and as long as you consistently use the same oil (separation problems) and mix it at around a 32:1 ratio (remember, more oil is more power and ring seal) you will not usually have a failure do to oil quality. Pick a good dealer, get your best price for a quality oil (not local gas station generic) and use it consistently.
but there are so many great choices
I don't recommend Castor-927 or any Castor oil unless you just like cleaning power valves and using a grinder to get the thick carbon off the core of your muffler.

For any given jet size can only flow a finite amount of liquid if more of the volume is taken up by oil then the fuel content will be lower.
Also More oil will generally lower the octane rating of the fuel.
Both these factors will take you closer to the detonation limit of your engine.
This should be considered in tuning for performance & reliability.
Pit Row
I've used K2 with good results and I'm using Yamalube R now. The best I've ever used is Bel-Ray H1R, however. I seriously had to recalculate my hours one time because the motor looked brand new when I took it apart. That oil is a full synthetic with a power valve detergent. Good stuff.
Motul 800 and Bel-Ray are H1-R is the highest.
If you're on the pipe a lot in MX, especially on a small bore 2 stroke, the higher flash point oil is a good choice. Running slower on a big bore could leave a mess, as the oil isn't being used as it was designed.
Here's a flash point chart I refer to, that I found:
Amsoil Interceptor - 183 F
Amsoil Dominator- 194 F
Amsoil Saber Pro - 237 F
Maxima Formula K2 - 240 F
Maxima Super M - 280 F
Maxima Super M Injector - 220 F
Maxima Castor 927 - 420 F
Maxima Bio 2T - 180 F
Motul 710 - 190 F
Motul 800 - 485 F
Motul Bio 2T - 255 F
Motorex Cross Power 2T - 230 F
Lucas Semi Synthetic - 182 F
Bel Ray H1R - 435 F
Bel Ray MC1 - 208 F
Bel Ray Si7 - 194 F
Castrol Power RS- 163 F
Castrol 2T - 194 F
Red Line Two-Stroke Racing Oil - 221 °F

Yes, the spooge and running you experienced was most likely jetting. Different oils require different jetting to get the best out of them.
My old man ran it in his circle track race sleds that turned BIG RPMS. Ran it in a V8 two stroke outboard on nitrous (drag boat).
I've used it in my stand up jet skis and moto bikes for many many years
