A look at the 2.5 Innards - DIY 20K mile service, including valve clearance check and shim replacement

Update: Buttoned her up last night and test rode this morning. A definite improvement! At first I thought it could be the placebo effect, after all that work but, no, it is definitely running more smoothly and strongly. I wouldn't think that a couple of tight valves would make much difference, so I think the timing must have been a tad off- now it's dead on!
All parts accounted for and not a single extra screw or bolt wondering where to go.

This project probably took five times longer than expected- waiting on parts, waiting on a tool that I failed to get in the first order, figuring out the compressors (with advice) on the camshafts, and then that dang clutch fiasco (trying to build pressure). That was the hardest and most frustrating of all, so at least the next time I won't have that to deal with and I'll have all the tools and shims ready to go. I will say that how things go together on this bike is very sequential. Getting things lined up and trying to fit big hands in small places to start screws, etc. ate up a good bit of time.

I'm hoping some of what I've learned will help someone else who decides to do their own 20K service. I need the written record too, because I have the memory of a gnat and don't want to start almost from scratch the next time.

I'm going to get some riding in and will come back and add more from where I left off from at some point soon. Just know that it can be done and if I can do it, so can you....
Sounds like a pretty involved job, considering all the tools you need & not having all the shims required etc might be easier just to get the Dealer to do it. I can't understand why you need valve clearances done @ 20K Yamaha clearances are done @ 40K & rarely need adjustment. Are they not set properly from new??
