Are you talking about disengageing the clutch before start up? If so, I have a few tips. Let us know. I've found 1000 rpm at idle when warm is just right. I've idled it at 750 rpm, but drops off. Sounds good tho. Being I seem to like fiddling with carbs.

I've invested in some mercury sticks and tuned them and forgot them. A good mechanic reminded me that different barometric pressures and humidities can make a bike run alittle different from one day to the next.
