What is the best 2 stroke oil to be used on the KTM's? And what ratio do you suggest?

You could get about 1,000 different responses on this one but, IMHO, any good name brand 100% synthetic premix should work fine. As for ratios, it depends on your type of riding. In a 300exc, if I were doing woods riding, I would go with a 50:1 mix. For wide open running like desert or MX, I would go with 40:1.
I'm using Spectro SX 100% Synthetic now because I like the way it smells and it burns real clean.

Best oil

I use Mobil MX2T (pure synthetic). I used to use Golden Spectro.

The only way to know what burns clean is by removing the top end and inspecting the power valve. I did not like the way my power valve looked when I replaced the last top end. I won't be able to tell how clean the MX2T is until I tear it down again and inspect the power valve.

I got the tip on Mx2T here on DRN. I am pleased with performance, and can't wait to take a look at that power valve!

Good Luck

Another plus, I order it from www.avlube.com, so I don't get gouged by the bike shops, by buying their 2-stroke oil pick-of-the-month.

They're right, you'll get a million different responses on brands of oil to use. My belief is that any quality, name-brand synthetic is fine. I've been using Silkolene Pro-2 fully synthetic in my 300 MXC and it seems to burn cleanly and doesn't foul plugs. I've been mixing it at 40:1. The main reason I run the Silkolene is because my dealer has the same motorcycle and runs the same oil, and I wanted to copy his jetting specs and I figured the best way to do that was to run the same oil. So far so good. I haven't had the top end off yet, so I can't verify how cleanly it's burning although my dealer swears it's the purest burning stuff he's used. But again, you'll get a hundred different tips and testimonials on two-stroke oil. Pick one you're comfortable with and I'm sure you'll be fine.
