What bike is it - 300? How are you using it?
I used to have a 300 and best jetting I found was 40, CCK and 180. That was in cool temp. I would go to 38 & 178 in summer. That's for tight woods. If I was doing lots of fast stuff I'd probably have it richer to be safe after a bad experience! I tried going very lean once and it was great in the woods but seized on a fast bit. That was on 35p & clip 1 on an N1EF - a lesson learned.
I don't think you can completely eliminate 4 stroking if that is what you mean by sputtering but the bike shouldn't hesitate when you open the throttle after slow running. If you completely eliminate 4 stroking on tiny throttle you will be so lean you are going to seize.
