Sent the bird in for a full tune up and valve adjust @ 31k miles.
Valves (no adjust needed), plugs, timing, carb remove and clean, new fuel filters, petcock diaphragm leaking vacuum and replaced. That's all.
Did not realize how much it had fallen off until riding it. Lordy mama, she's so smooth and fast now, it's a real effort to keep her below 90. This bike is the tits again. Money well spent.
