What's the best two stroke oil for my 325 Sherpa(159) and what ratio do you recommend?

castrol TTS at 50:1 can`t go wrong with this,it is expensive though!!

I agree with the oil but is 50:1 a bit rich?

Thanks guys, I trialled the bike for the first time last weekend and had a great time, I ran it on the same mix as my lads Gasser which was 50:1 Ipone Strawberry special but by the end of the afternoon it started chuffing a bit and the plug was dry but very black. I suspect the carb (Bing) needs a bit of fine tuning on the mixture and possibly worn components.

I think with modern oils it is better 50:0.75 that is 1,5%. I use Myto oil in my Bultaco

I use whatever it says in the owners manual using the same oil that it ran on in the 70s (my dad laid the bike up along with lots of oil) Duckhams 2T. Not had a problem with it in either of my bikes one is a fresh rebuilt engine and the other is the original factory build from new.

Check the slide, should have no step. Set the carb to be as lean as poss on the float level. 4/5 beats before it stops is about right for tickover (none).
