I am looking for some help regarding the changing of the front fork oil on my 2000 WR. I have about 375 total miles on my bike and have never changed the fork oil, so my questions are: 1. How often (in miles) should I change the oil? The manual says after break-in, then every 1000km.(620 miles). 2. Can the oil be changed without removing the forks from the bike as the manual says? 3. The manual says the oil capacity is 19.4 US oz. Is that per fork leg or for both? 4. Is there any truth to the bleeding of air from the forks before each ride? 5. Does anyone have a simplified procedure to change the fork oil?
