2007 with that sort of miles...you are riding more than I.
Looks to me that you actually do keep the bike clean, or at least more clean than I feel I keep mine.

With the only mod listed in your signature as the white spacer, it looks like your bike is treating you well, so you must be treating your bike well too. Have you opened it up to check your cam chain tensioner yet? I'm curious to how far out it might be by now, my 2005 will turn 10k still this year, and I think I will have a look at it over the winter.
Congrats on the milestone
