Where they little black chunks or black shavings? Black shavings are usually clutch plate wear, I believe.
Black chunks definitely point to dampers. I am in the process of doing this now, the engine is out and sitting on my garage floor.
When I first got the bike, the concept of an engine pull would scare me. Now I am just excited to get her going again. The internal engine work required is very easy, and is actually the quickest part of the job. I'd say I had the internal work done in under 30 minutes (strap-wrenches are awesome). The tight spaces during dis-assembly and re-assembly are what get to you.
