It would be great if you could post your personal Mikuni carb set up including jet sizes, needles, clip positions, float height, airscrew etc. and how your bike runs/behaves with your set up.

Its also useful if you add the altitude you took as reference and maybe the temperature. And of course which bike you have....

Having an own thread about jetting the 2017 smokers makes it easier to find the required information. Hope you agree :smokin:

Is it worth people saying what 2t oil they are using to? I know it sounds daft but my 200 runs differently on Motorex compared to Exol compared to Saber 100:1 (will try this again but need a jet tweak). It runs fine on all but some are cleaner than others and you can feel a difference.

Just checking, the silver screw on carb now is the air screw and not the little brass one, correct? Sure was the other way round on old carbs
No, it's the other way round :eek::rolleyes:

silver is tickover, little brass is AS

I can only assume it's fine tuning but perhaps you should let the Greek have a look at it

Going to have ro admitt defeat, I think the air screw is the silver one and book right and the brass is the idle speed, though I am think as fook sometimes

Because I felt the 37.5 on 2 was a tad lean and with the 40 on 2 it's seamless and strong
