6,000 miles checkup - go to a dealer or do it myself?

Yes, 3 sizes in my tool box. "Google" Robertson screws or Robertson screw drivers and you will probably get a pic of the design. I wish the bikes had Robertson heads instead of Philips. The main reason is that the Philips on a Japanese bike is actually of Metric dimensions so the normal SAE Philips tend to slip. I have found though, an impact driver has very good Philips tips that do not slip. Works well but is very heavy for a screw driver.
