So, my 09 has about 20,200 miles on it. My manual says to change fork oil at 50,000 miles. I've heard in the past that the fork oil interval was 20,000 miles. So, when do you guys change your fork oil? Are you still using the 20k figure or 50K or something in between. I'm gonna upgrade to the SE heavy oil which I heard helps prevent excessive front end brake dive. I'm not experiencing any problems right now so I'm thinking about leaving it alone for now.
