Bike is due for an oil change. I usually do this myself, but with the 8,000 miles on the bike, I am wondering if I should take the bike to a shop. I am a certified aircraft mechanic, snap-on are as basic as a fork and a knife to me. Question is... is the extra money involved in a detailed inspection and 8,000 mile tune-up (and possibly Dyno and tune of my Anger Management EMI) worth it? I know a lot of maintenance can't be written on paper cause it is based on personal feel and experience. Should I sacrifice this professionalism and do it myself (I have the tools and the resources, just lacking the experience with this machine).
