At what sort of revs/power are you rolling off the throttle? Roll-off is a useful test for main jet at ¾-full throttle with a few revs dialled in. When you roll off (from smooth full throttle acceleration to, say, 7/8 throttle), the tendency is for the mixture to richen a little, so if she actually ‘gains’ when you roll off that means you were too lean and can go up a jet. If the motor is unhappy at roll-off (as your seems to be), you were probably too rich anyway and should drop in the smaller jet.
3 jets is a big jump for a muffler and de-snorkel – I suspect you’ll have a happier bike with the 150.
Half a spacer shouldn’t be far off. As for the idle, have you uncovered the mixture screw and adjusted it? Raising your needle shouldn’t affect idle speed too much, but it can affect idle stability on roll-off.
To set idle mixture, best to have the bike ticking over slightly high (just turn the idle screw to give the motor a couple of hundred revs more than normal idle). With the idle speed set a little high, turn the mixture screw by ¼ turn at a time until you get the highest variation engine speed (maybe just a perceptible change in tone for 20rpm or so) – turn left until it starts to drop and note where it is, turn right until it starts to drop and note that also, then set the screw midway between. When you’ve done that, set your idle speedback to where you want it.
With that set right, she shouldn’t stall.
