I recently purchased a 1994 Kawasaki KDX 200 2 stroke. I have never owned a 2 stroke and do not know what oil would be good for it or a good fuel/oil ratio. Any advice would be greatly appreciated, thx.

Welcome to kdxrider.

What terrain are you riding on?

What skill level are you?

Are you racing or not?

I've experimented and settled on Motul 710 mixed 40-1.

I run Amsoil @ 50:1

Oh boy, the oil can-o-worms.

I always ran Maxima Castor 927 at 40:1. However, having your bike properly jetted is important when running 927. I've now switched to Lucas semi-synthetic, at the same ratio, due to easy availability from auto parts stores and the KDX, and my GasGas, seems to do well on it.

On ratios, run anything between 32:1 and 50:1, as long as the oil says it supports the ratio, and jet accordingly and stick to it. Changing ratios without changing jetting causes a poor running bike.

I agree...let the war begin over everyone's choice of oil.

My opinion...Yamalube 2R or Motul 710 (800 if you're a hardcore racer). I always used Motul but switched a while back due to what was available locally. Makes it a lot easier when I need oil and quick if the kiddos want to ride last minute and we're out of oil. I always ran 32:1 unless the oil manufacture specified their own ratio. Either way, pick something, stick with it and jet for it. Being consistent and jetted correctly is much more important.

I run Motorex Cross Power 2T in my KTM at 40 - 1 - no spooge.
I run Motul in my KDX at 40 - 1 - no spooge.
I dumped the Motorex in my KDX because I'm too lazy to go buy gas to take the grand kids riding - spooge like I've never seen before.
I compared the characteristics on the two oils, and although the Motorex is higher flash point, I did.n't expect such a dramatic difference.
Not sure what I'm going to do, but I want one oil type around here. Probably Motorex at 50 - 1.

Sounds like the KDX needs to be leaned out some then. I ran super high flashpoint Castor 927 and didn't get spooge riding nasty slow singletrack. It's all in the jetting.

+1 for Lucas, 32:1 per the manual, but I'll probably start going 40:1 after I break in my new top end.
