You want them to open as close together as possible for max performance out of the CV side, the side providing the most air and fuel, but you must make sure that the CV is fully closed when the throttle is at zero or the idle circuit will be completely messed up. If you are into relaxed in town driving, you can go ahead and set a big gap. The bike will be super tame and get better mileage but the CV carb will never open completely. Of course it doesn't open completely anyway unless you have done the mods from the off-the-road carb kit.
Somebody will probably chime in and recall the exact factory recommended setting, but I liked mine to open very early for maximum fun factor.
can you please elaborate on this... many years ago i altered the timing so that the right carb opens pretty quickly almost as soon as the left carb... when i rotate the throttle i see the main carb open, and a short while after the other carb with the diaphragm opens....
What i tend to find, is if i twist the throttle slowly when in neutral the engine picks up smootlhy.. but if i twist the throttle fast the engine just dies... what does this point too ?
is it to do with the mixture, or the balancer screw on top
