32:1 Golden Spectro is what I run in ALL my 2-strokes. I enjoy not having to rering for 13 years.
So you've been running this since you were 6?

I use baby oil at a 5:1 ratio and there's always a trail of chicks in my wake yearning for me to impregnate them.

I wish,, The blaster went 13 years before I tore it down to replace crank bearings, my uncle's TM100 literally lasted until the frame fell apart and he never put a set of rings in it. And it's a similar story for every other 2-stroke my family has owned

I have run Maxim K2 at 40:1 and 36:1 on 91 pump gas... Never had any luck running at those ratios and keeping a top end. Currently at 32:1 but the Suzuki manual says 20:1 for the 250 engines.

How do you guys get away running such a lean mixture?

In my 250 I run 32:1 with BP 93 pump gas with Klotz super techniplate oil. Smells great, smokes, but it's all cleaned out by the time I hit 4th wide open thru the field. Once it's warmed up, it still smokes a little, but revs right up, smells great. I feel like it's the perfect mixture of protection and performance. I have ran it at 40:1 before, but I just felt like 32:1 was safer and better.
When I raced motocross on a yz125, I used Blendzall castor oil at 50:1 with 110 octane. I would replace the piston and rings once per season and I rode ALOT!

Oil is better 2 today then it was back then. If you got your jetting right should have no problem at 32 to 1. The lt will idle safe at 80 to 1 I think Jerry said once. They say if your going to run wide open throttle all the time to run more oil in them. 24 to 1 or 20 to 1. I add more to mine when I drag race .

I have an 86' and I ran bel ray mc1 and just before I stopped riding it, I bought some h1R, ran 50:1 on pump gas(91 octane), it only had problems with cutting out after any extended period of Full throttle. I bought some racing fuel and mixed the oil to 30:1. It ran a tons better  I just bought an 88' but it doesn't run, so I couldn't tell ya what to mix for the power valve years. It looks like a majority of people are saying 32:1 or better. Me, I couldn't care less if it smokes. I'm going the other way. Lol
