Craig,
I've never done mine but just got my new seals and clips a couple days ago so I'm planning to within the next week or so. I dropped the exhaust on my lower cylinder a couple weeks ago to get a look inside and mine look like they could use a good scrubbing. They were also sticking occasionally.
Tell me about pulling yours. How did you get the shafts out? I was going to try to configure a puller if need be. Once the shafts are pulled I assume the the valves simply come out through the exhaust in two pieces? Did you need to do any cleaning inside the ports?
Thanks for any info, it will probably be helpful when I tackle mine.

Dan
