when you say "kicking" are you talking about the shift lever on your left foot?? because i had that problem too for nutrual to 1st and back. all i did was change the oil to a better brand. then it was fixed. but there is an adjustment inside the shifting case. i just don't know where it is. the machanic here told me that.
or maybe your clutch liner dosn't have enough flow for the oil to get into it. the machanic alsot me about some bikes having this problem. they had a bike at the dealership that someone baught, it only had 1 klm on it then the guy brought it back because he was having trouble with shiftin. the machanic changed the clutch lining, but bedoe doing to he also added a few holes in a plate that alows the oil to come in, he put one more hole on bothe sides of the place, he said one side oil comes in and the other oil goes out, with the added holes it alows more oil to lubracate the clutch when riding. less friction means smoother shifting. it worked, the bike hasn't been back for the same problem..
when hope that info helps. alittle.
