Mate is this on a fazer 600 ?
If so make sure you have a decent torque wrench to do the front sprocket up correctly as these have been known to undo themselve's and wreck the input shaft
In the kit from busters I doubt if it will have a new front sprocket nut or washer, i would make sure I had these from yamaha before starting the job [smiley=thumbsup.gif] I can get the part numbers for you if needed
I would need to know year of bike first though [smiley=thumbsup.gif]
