Got my 600 mile service finished over the last two days. Oil/filter change yesterday, and valves, other checks today. Amazingly, both valves were exactly in spec, right where I was planning to put them if they were not: Exhaust .004" and intake .002" -- right in the center of the tolerance for both. Still, I learned how to remove the tank, find compression TDC, all that jazz. Definitely the simplest bike I've worked on. I bumped the idle speed up a bit ( 1/2 turn CW on the brass screw was enough to hear it rise ) after having some problems with the bike stumbling off idle. Like when you go to rev throttle up, it coughs/bogs and doesn't respond before revving up. I actually stalled the bike leaving the gas station yesterday because of this. This is a fairly new problem that seemed to be getting worse. Increasing the idle helped a bit, but the stumble is not completely gone. I'm becoming quite annoyed with the fueling on this bike. The factory map is god awful. I'm looking hard at the power commander -- not for more power because that won't help, but just to make the bike run right. I don't need the 89MPG I've been getting -- I will settle for fewer MPG and an engine that runs smoothy and responsively.
