I've had clutch issues with my 08 since the first winter it experienced (about 6 months into ownership). The clutch lever goes limp (easy Brian!) and engages immediately upon releasing the lever from the handgrip. The dealer has dicked around with it numerous times and most solutions were to bleed the fluid, which is a decent bandaid. The fluid gets black grainy particles in the bottom of the reservoir and I'm not sure where that comes from.
Upon looking at it myself, I removed the slave cylinder and found a tremendous amount of corrosion, gunk, and brown fluid in the cavity. Upon showing the dealer, they replaced the oring on the clutch pushrod down at the slave cylinder. It worked much better for a couple of years until it started again. In fact, the clutch died on me about two blocks from my house the other day when it was very hot. Upon taking off the slave cylinder (which had to be pried/beat to remove), I found a similar situation plus a MANGLED oring. I put a new one in yesterday and it is working well again.
I am perplexed because the master cylinder fluid system is completely separate from the pushrod/oring system, but somehow one affects the other.
I've found that replacing the fluid each year does tend to delay the problem, so that's my current solution. A Mity Vac pump kit is available from Harbor Freight for about $30. It's worth every penny.
