50:1 Fully Synthetic Safe

Just wandering if this ratio is safe for a 66cc bike? (50:1)

Just broke in, looking to rid the crappy 20:1 ratio with mineral.

Does anyone else run this ratio?

Performance a bit better?

Dangers?

Cheers
 
I just switched over to synthetic and Iam playing it safe by doing what they say on the bottle for my size motor a 66cc. (30 to 1)
 
I personally would only run a blended oil such as Klotz Super Techniplate 2-Stroke Oil or Maxima 927 if using that ratio.

i've ran maxima super m all my life which is a syn petro blend at 50:1 I just recently started usin amsoil sabre at 70:1 to 80:1. I ran 70:1 in my cr 250 this past weekend with the vp ms103 oxygenated race fuel. Its never ran so crisp wowsers
 
I run Red Line pure synthetic 50:1. Why? Because that's what Red Line recommends. My bike doesn't smoke and you can barely smell it.
 
ams oil synthetic 50:1 on my last build. Ran quite a lot time with much abuse.

It finally died, but I think hydrolocking the engine once or twice, and always running around WOT right from start up killed it... not the oil.
 
I would have to go with the trend here and say 50:1 is fine with the right oil. Been runing Amsoil and that seems fine.
 
In my china 2-strokes I've run Maxima K-2 fully synthetic and Maxima 927 at 50:1 with no probs after break-in. I use the Maxima 927 to break-in all of my 2-strokes at 30:1.....love the smell of that castor!

Important thing is to NOT run synthetic at break in. I'll probably do 50 miles or so on my new engine (if it ever shows up... been waiting 3 weeks now). The 50:1 or so afterwards. If I got well over 4000 miles on the last one with a few hydrolocks and serious abusive abuse, I think this next one should do just fine.
 
Just wondering if anyone has tried lucas semi synthetic? I found at a local auto parts, says no smoke I'm going to give it a try at 40 to 1.

I used it for years and occasionally do still time to time. Never had a problem but I ran at 40:1 with it.
