Oil change interval

[roadracer311]

I'm sticking with every 5k miles, which looks like it will also be my annual mileage. (I mainly use my motorcycle for transportation)

With respect to the RMS problems. I have a theory: oil that's even slightly too full may contribute to leaks. By too full, I mean within 1 bar of the full mark on the dash. I work on motorcycles for a living, and I've noticed that on the few dry sump motorcycles we work on, the oil level increases quite a bit when they're hot. So if I check one warm, it will be ok, but check it again all the way hot, and it's over full. The end result of an over-full bike is an over-pressured sump and oil oozing out everywhere that it can. I'm thinking this same thing (being more than 8/10ths full) could also be a contributing factor to the coolant overflow tank failures.
