Thats a pretty important service interval. I've taken my K5 over to sportbike dynamics in Petaluma, 707 762 6700.
His name is Alan. He races AFM and has been working on gixxers for a long time so he knows these bikes pretty well.
It's a bit of a ride from WC and the shop rate is not cheap. He has a rather unique personality, so it takes some getting used to.
I've been a regular customer for a couple years now, and one things that has never wavered is his commitment to doing quality work, letting you watch so you can see exactly whats being done and to ask questions.
It's expensive, but knowing that your bike is mechanically sound and safe to ride is worth the money spent.
Just my 2cents.
