I am really considering swapping in an '06 YZ450F exhaust cam when I pull off my valve cover soon to check the valves and replace the timing chain (preventative - about 125 total engine hours and I'm riding it a lot these days). Can anyone tell me if I need any additional parts for the job, such as the guides (or 'dampers' - parts 9 and 10 in the fische) or circlips (part 3) or anything else, or are those things just replace-as-required type parts that I need to open up and inspect? I realize I may need to order shims if my valves are out at all, and I'll do that when I know where they are currently with it apart and the new cam installed. This is my first venture into a modern four stroke motorcycle top end/valve train and just wanted to make sure I order what I need in one shot if possible.
Here is the parts source I use:
