Jd Jet Kit

all right well i jetted my bike the other day with this kit (2002 cr 250 mikuni tmx flat slide carb) and it made a big difference. the plug color is a nice crisp brown and the top end response is nice. i do have a little bog from idle to when i open the throttle especially if i slam it fast. is this my slow jet or my clip position that needs to be adjusted. also i know it's cold and all outside right now in idaho but im bored and would like to get this jetted spot on that way i know how to do it come spring. oh and there is a decent amount of purple smoke still coming out the silencer is that just two strokes cuz im pretty sure when i jetted my yz250 with a kehin pwk carb i eliminated pretty much all the smoke and im sure it's not my crank seals because i just re did the top end and checked the seals. any suggestions are very well appreciated.
