You don't need a lot of play in the throttle. It won't help and may cause problems. My recommendation to you would be to go up one tooth on the front sprocket (I have a video for that mod in the tech section). You can also shift earlier in the rev range to reduce jerkiness. You needn't do anything more than that to improve your experience.
