Haven't bought the service manual yet, but the first valve check was done at 12000 miles last week (no shim change required).
My comfort factor for range is fill up at 150 miles, but that is running fast and loaded (aerostich tank bags and jesse 10in bags). My calculation of the range based on 4.2gal is anywhere from 186miles to 230miles. That is heavily dependant on how hard I'm rolling. I am not easy on the the throttle.
Personally, I am amazed at folks who pull 65MPG+....I can't seem to get there on the interstate. Around town, I normally see around 50MPG.
+1 on the cruise all day at 80MPH. That's right around the sweet spot on this bike.
Love this bike.
