Why do these custom character animations lag? --Update--

I've been experimenting with my custom characters in my spare time for some weeks now, attempting to pinpoint the source of a heinous spike in lag. I've finally found that whenever the animations in my custom character are active, my framerate dips drastically. For example, when I begin walking and stop, causing the idle animation to play, my FPS will dip about 5 - 6 frames and Remain at that level. I'm thinking that perhaps the animations are being fired In rapid succession however I am unsure. Can anyone provide some insight and help me debug this? Thanks. The script that animates the model is below.

--UPDATE-- I've removed the animations that don't seem relevant to the problem, and added a debounce. The debounce seemed to correct the issue of the idle animation firing too many times, however if the player taps the w quickly enough, the frames will begin to dip again.
